About the 7193 Printer
About the 7193 Printer
The 7193 thermal receipt printer is fast (at 600 lines per minute), quiet, and very
reliable. With thermal printing technology, there is no ribbon cassette to change,
and paper loading is extremely simple. The printer is small enough to fit almost
anywhere and is easy to use with the receipt exiting from the top. There is no
journal as it is kept electronically by the host system.

Thermal Printhead
The 7193 uses a thermal printhead which is extremely fast and quiet. Because it
uses heat to print directly on paper, there is no cassette or ribbon to change,
eliminating soiled fingers and paper dust.
The printhead is designed for a very long life, but it may be replaced if needed.
Only a trained service technician may replace the printhead. See “Solving
Problems” later in this book to determine if the printhead needs to be replaced. If
the printhead needs to be replaced, contact your Axiohm authorized service
organization. See “Cleaning the Printer” later in this chapter for cleaning
instructions for the printhead.

7193 Owner’s Guide
Ordering Paper and Supplies
Thermal receipt paper and other supplies can be ordered from several
recommended and qualified suppliers.
Ordering Thermal Paper
The 7193 requires “fax grade” thermal paper with the following dimensions:
•
•
•
Diameter: 80 mm maximum (3.15 in.)
Length: 83 meters (273 ft.)
Width: 80 mm ± .5 mm (3.15 ± .008 in.)
The paper must not be attached at the core or the printer will be damaged when
the paper runs out. When the paper runs out, the printer stops printing and turns
on the Paper Out light (red) on the operator panel. There is no indication or
automatic signal when the paper runs low. It is recommended that you use a
paper roll with a colored stripe at the end of the roll to indicate that the paper is
running low.
Recommended Suppliers
The grades of paper listed here will give the best print quality. When more than
one stock or paper grade number is listed, the first number (standard density)
provides better image density. You may order paper directly from AT&T Global
Information Solutions. Contact your Axiohm supplier for ordering paper
manufactured by Kanzaki (paper grades listed on the next page).

About the 7193 Printer
Cleaning the Printer
There is no customer maintenance required for the 7193. However, you may
occasionally clean the cabinet as needed to remove dust and finger marks. Use
any household cleaner designed for plastics, but test it first on a small unseen
area. The cabinet materials and finish are durable and are resistant to the
following items:
•
•
•
•
•
Cleaning solutions
Lubricants
Fuels
Cooking oils
Ultraviolet light
If the receipt paper bucket is dirty, wipe it with a clean, damp cloth.
Caution: Do not spray or try to clean the thermal printhead or the inside of the
printer with any kind of cleaner as this may damage the thermal printhead and
the electronics.
If the printhead appears dirty, wipe it with cotton swabs and rubbing alcohol. If
spotty or light printing problems persist after cleaning the thermal printhead, see
“Solving Problems” later in this book.
Note: The thermal printhead does not normally require cleaning if the
recommended paper grades are used. If non-recommended paper has been used
for an extended period of time, cleaning the printhead with cotton swabs and
rubbing alcohol will not be of much benefit. See “Recommended Suppliers”
earlier in this chapter for the recommended paper grades.

Setting Up the Printer
Choosing a Location
The 7193 is compact and requires little counter space. It may even be mounted on
a wall if space is at a premium. See “Mounting the Printer on a Wall” later in this
chapter. The power supply may also be mounted on a wall or under a table. See
“Mounting the Power Supply on a Wall” later in this chapter. Be sure to plan for
the length of the communication and power cables when choosing a location.
Make sure there is enough room to open the receipt cover and change the paper.
The following illustration shows the actual dimensions of the printer, but leave
several inches around the printer for connecting and accessing the cables.

7193 Owner’s Guide
Setting Switches
A group of switches, called DIP switches, located on the bottom of the 7193 is
used for the following purposes:
•
•
•
•
To set variables for several printer functions (see the sections for the various
printer functions in “Level 1 Diagnostics” in the “Diagnostics” chapter)
To perform diagnostic tests (see the sections for the various diagnostic tests
in “Level 1 Diagnostics” in the “Diagnostics” chapter)
To set communication parameters for the RS-232C communication interface
(see “RS-232C Switch Settings” in the “Communication” chapter)
To set the data buffer for the Parallel communication interface (see “Parallel
Switch Settings” in the “Communication” chapter)
Caution: The DIP switches are set at the factory to predetermined settings and
should generally not be changed. If you must change the settings do so carefully
to avoid changing other functions.
Before changing any of the switches, first run the print test to print out the
current switch settings on the receipt. See “Testing the Printer” later in this
chapter for instructions on running the print test and for a sample printout.
Note: Switch #1 is used to toggle between regular communication with the host
system and Level 1 Diagnostics (used for the printer functions and level 1
diagnostic tests) as described below:
•
Switch #1 set to OFF: printer is ready to communicate with the host system
and receive data (online mode)
•
Switch #1 set to ON: printer is in Level 1 Diagnostics (setup mode)
If you want the printer to communicate with the host system, be sure switch 1 is
OFF. Use a paper clip or other pointed object to set the switch.
For additional information on the setup mode (Level 1 Diagnostics), see the
“Diagnostics” chapter.
Note: Some 7193 models may appear slightly different than what is shown in the
illustration. The procedures are the same for all models unless otherwise noted.

Connecting Cash Drawer Cables
The cash drawer option allows up to two cash drawers to be connected to the
printer in a system with a PC that has no connectors for the cash drawer cables.
The cash drawer cables usually come with the cash drawer.
The cash drawers are operated by software command from the host system
through the printer. For additional information on the printer commands used by
the host system to activate the cash drawers, see “Commands” later in this book.
1. Plug the cash drawer cables into the connectors on the printer.
The connectors are standard phone connectors.
2. If only one cash drawer is used, plug the cable into the connector labeled 1.
Note: Some 7193 models may appear slightly different than what is shown in the

Loading and Changing Paper
The 7193 features extremely simple paper loading. See the next two pages for
detailed illustrations.
If you are loading paper for the first time and have already taken the roll out, go
to “Putting In the Paper Roll” later in this chapter. If you have not taken the roll
out, continue with the following instructions. Although the illustrations show a
used roll being removed, the instructions still apply to loading paper for the first
time.
When to Change the Paper
You will need to change the paper when you see a colored stripe on the receipt
paper or when the Paper Out light (red) on the operator panel turns on.
•
Paper Low Stripe
When the paper low stripe appears on receipts being printed, change the
paper as soon as possible to avoid running out of paper part way through a
transaction.
•
Paper Out light
When the Paper Out light (red) on the operator panel comes on, the paper is
completely out. Do not run a transaction without paper: the data may be lost.
Caution: Do not operate the printer or host system if the printer runs out of
paper. The printer will not operate without paper, but it may continue to accept
data from the host system. Because the printer cannot print any transactions, the
data may be lost.

Setting Up the Printer
Mounting the Printer on a Wall
Use the wall-mount kit to mount the printer vertically on a wall. See “Ordering
Paper and Supplies” in the chapter, “About the 7193 Printer,” for information on
ordering the printer wall-mount kit.
The kit contains a mounting bracket, screws with plastic anchors, and a label.
Once the printer is mounted on the wall, the operator panel will be upside down.
The label corrects this so the panel can be easily read.
Select a wall that is accessible, but away from main traffic to keep the printer
from being bumped or knocked off. Be sure there are no hidden wires or other
obstructions in the wall where you mount the printer. Keep in mind the length of
the cables when mounting the printer on the wall.
Be sure that the rubber pads have been attached to the bottom of the printer. See
“Attaching the Feet” earlier in this chapter. The rubber pads help the printer to fit
snugly against the mounting bracket.
You will need a 1/ 4 inch drill bit and either a Phillips or standard screwdriver
(screws are combination Phillips and pan-slotted).
1. Using the bracket as a template, mark and drill a hole for each plastic anchor
1.25 inches deep.
2. Insert the anchors into the holes so they are flush with the wall surface and
screw the bracket against the wall, tightening the screws so that the plastic
anchors expand and hold firmly in the wall.
Do not overtighten the screws.
Note: Because the power cable and communication cable connect to the bottom
of the printer, they must be connected before the printer can be attached to the
bracket. If you haven't connected the cables to the printer, do so now. See
“Connecting Communication and Power Cables” earlier in this chapter.
3. Line up the tabs of the bracket with the slots on the back of the printer and
attach the printer to the bracket.
4. Place the label on the cover.

Solving Problems
Solving Problems
The 7193 printer is a simple, generally trouble-free printer, but from time to time
minor problems may occur. For example, the power supply may be interrupted
or the printhead may overheat for some reason.
Lights on the operator panel will signal that something may not be operating
properly: one green light and one red light may either flash or glow continuously
as described in the following table and on the following pages.

Correcting Problems
Operator-Correctable Conditions
The following conditions can be corrected generally without calling for service.
However, if problems persist, contact your service representative. See
“Contacting a Service Representative” on the next page.
Paper Out
Replace the paper roll. Do not operate the printer or host system if the printer
runs out of paper. The printer will not operate without paper, but it may continue
to accept data from the host system. Because the printer cannot print any
transactions, the data may be lost.
See “Loading and Changing Paper” on page 19 for more information. See
“Contacting a Service Representative” on the next page.
Knife Failure or Paper Jam
A problem or jam has occurred with the knife. Open the receipt cover and
visually inspect the knife inside the cover. Clear any jammed paper you can see.
Tear off any excess paper against the tear off blade.
Contact your service representative if this does not resolve the problem. See
“Contacting a Service Representative” on the next page.
Receipt Cover Open
Check that the receipt cover is completely closed. You can tell if it is not closed
properly if it swings open easily. When closed properly, it requires some exertion
to open because of the snug fit.
Service-Related Problems
The following problems may require you to contact your service representative to
correct the problem.
Print Head Over/Under Temperature
There is a problem with the temperature of the printhead. It must remain within
a certain temperature range to operate properly. This problem will most often
occur when the printhead overheats rather than running under temperature.

7193 Owner’s Guide
Solving Problems
The printhead may overheat when printing in a room where the temperature is
above the recommended operating temperature or when printing graphics
continuously. In either case, the printer will shut off. See “Appendix A:
Specifications” for information on the recommended temperature range for
operating the printer and on the restrictions of continuous graphics printing.
If the operating temperature is too hot, adjust the room temperature or move the
printer to a cooler location. If the printhead is overheating because of printing
graphics continuously, reduce the demand on the printer.
If the printer continues to overheat, contact your service representative. See
“Contacting a Service Representative” on this page.
No Power to Printer or Power Voltages Incorrect
The power being supplied to the printer is not in the normal range. Check that all
connections are correct. Make sure the power supply is plugged in and that the
printer is on-line.
Contact your service representative if this does not resolve the problem. See
“Contacting a Service Representative” on this page.
Print is Light or Spotty
The printhead may be dirty. Clean it with cotton swabs and rubbing alcohol.
Caution: Do not spray the thermal printhead with household cleaner as this may
damage it and the electronics.
Note: The thermal printhead does not normally require cleaning if the
recommended paper grades are used. If non-recommended paper has been used
for an extended period of time, cleaning the printhead with cotton swabs and
rubbing alcohol will not be of much benefit. See “Recommended Suppliers” on
page 4 for the recommended paper grades.
Contact your service representative if the problem is still not resolved. See
“Contacting a Service Representative” on this page.
Contacting a Service Representative
For serious problems, such as the ones mentioned in the previous section, contact
your Axiohm authorized service organization to arrange for a service call.

Diagnostics
Diagnostics
The following diagnostic tests are available for the 7193:
•
•
•
Level 0 Diagnostics
Performed during the startup cycle
Level 1 Diagnostics (setup mode)
Available in a dedicated environment and accessed through the DIP Switches
Level 2 Diagnostics
Performed during normal printer operation
Level 0 Diagnostics
The printer performs level 0 diagnostics during the startup cycle when power is
supplied or the printer is brought on-line. Level 0 diagnostics comprise the
following actions:
•
•
Motors are turned off
Microprocessor timing is checked, CRC check of the firmware ROM is
performed, external RAM is read (failure causes level 0 diagnostics to stop;
the printer beeps once when the test is successfully completed)
•
•
•
Checks if paper is present
Homes knife (failure causes a fault condition)
Checks if receipt cover is closed (failure does not interrupt the startup cycle)
When the last step is complete, the Paper Feed button is enabled and the printer
is ready for normal operation. Information about the test is available to the
communication interface through the commands.
If the printer has not been turned on before, or a new EEROM has been installed,
the default values for the printer settings (set in Level 1 Diagnostics) will be
loaded into the EEROM. The printer beeps twice when this occurs. See the tables
in “Level 1 Diagnostics” for the printer settings. If the printer beeps twice at any
other time, it indicates that the EEROM has failed.

Diagnostics
7193 Owner’s Guide
Level 1 Diagnostics
Level 1 Diagnostics (setup mode) allow you to change the settings for various
printer functions (described on the following pages) and to run certain tests
using the DIP switches.
Keep the following information in mind when changing the settings:
•
Turn the power off (not required, but recommended): press the On Line
button (although the printer still receives power, this is sufficient for
changing the DIP switches)
•
•
•
•
•
The settings can only be changed when the printer is in level 1 diagnostics
(setup mode): switch 1 must be set to On.
Turn the power back on. The printer beeps, and the On Line light (green)
blinks.
Once the settings have been changed and stored in the EEROM, the DIP
switches must be set back to the on-line settings for the printer to operate.
The stored settings for the functions are printed with a dump of all resident
characters during a print test. See “Testing the Printer” on page 23.
The default settings are set at the factory and are stored in the history
EEROM.
Caution: If you change the switch settings, be sure they are the correct settings
for that particular function or test to avoid accidentally changing the settings for
another function or test. If the settings are accidentally changed, use the switch
settings shown in the tables throughout this section to change those settings back.
If you need assistance, contact your service representative.

Communication
Communication
Communication Overview
In order for a receipt to be printed, a program must be in place that translates the
data from the host system into a language that the printer can understand. This
program must tell the printer exactly how to print each character. This chapter
describes how to create such a program or modify an existing one.
Interfaces
In order for the printer to communicate with the host, a communication link must
be set up. The 7193 supports the following three communication interfaces:
•
•
RS-232C Interface
Parallel Interface
Each of these has a protocol associated with it that the host must understand and
adhere to. Only when the interface parameters are matched and the proper
protocol is used will the host and the printer be able to communicate. See the
respective sections in this chapter for a description of the protocol associated
with each type of interface.
Sending Commands
Once the communication link is established, commands can be sent to the printer.
This section describes how to send commands to the printer using DOS and
BASIC. This section does not take into account the necessary protocol, but is
meant as a general introduction to how the printer functions.

Communication
7193 Owner’s Guide
Using DOS to Send Commands
One way of getting commands to the printer is to send them directly from DOS.
For example, the command
COPY CON: COM1:
sets the computer up such that the Hex code corresponding to any key that was
pressed would be sent to the communication port COM1 when the COPY mode
is exited. If the printer is connected to COM1, then the data will go to the printer.
Exit the COPY mode by typing
CTRL Z
and then pressing the ENTER key. Once the computer knows to direct data from
any print command to the proper port, commands can be sent from any software
program.
Using BASIC to Send Commands
In BASIC, printer commands are sent as a string of characters preceded by the
LPRINT command. For example,
LPRINT CHR$(&H0A)
sends the hexadecimal number 0A to the printer, which causes the printer to
print the contents of its print buffer. Previously sent commands tell the printer
exactly how this data should appear on the paper. For example,
LPRINT CHR$(&H12); "ABC"; CHR$(&H0A)
sends the Hex numbers 12 41 42 43 0A to the printer. This causes the printer to
set itself to double wide mode (12), load the print buffer with “ABC” (41 42 43),
and finally, print (0A). Again, the communication link that the BASIC program
outputs to must be matched to that of the printer.
RS-232C Interface
The RS-232C interface uses either XON/ XOFF or DTR/ DSR protocol. For
XON/ XOFF, a particular character is sent back and forth between the host and
the printer to regulate the communication. For DTR/ DSR, changes in the
DTR/ DSR signal coordinate the information flow.
The RS-232C version of the 7193 offers the standard options which are selected
with the DIP switches. The switch settings are shown on page 50.

Communication
XON/XOFF Protocol
The XON/ XOFF characters coordinate the information transfer between the
printer and the host system. The printer sends an XON character when it is ready
to receive data and it sends an XOFF character when it cannot accept any more
data. The software on the host system must monitor the communication link as
shown in the following flowchart in order to send data at the appropriate times.
13 HEX

Was an XON
or XOFF charactor

Send Data
XON character = Hex 11.
XOFF character = Hex 13.
DTR/DSR Protocol
The DTR signal is used to control data transmission to the printer. It is driven
low when the printer is ready to recieve data and driven high when it cannot
accept any more data. Data is transmitted from the printer after it confirms that
the DSR signal is low.

Switch Settings
The DIP switches are located on the printed circuit board and are accessed from
the bottom of the printer. You do not need to remove any covers to change the
DIP switches.
The DIP switches are used to set the RS-232C parameters and the Data Error and
Data Buffer options as shown. These parameters must match those of the host
system in order for the host system and the printer to communicate. See “Level 1
Diagnostics” in the “Diagnostics” chapter for more information.
Caution: The switches can also be used for setting other functions and tests. Be
careful when setting the switches for the RS-232C settings that you do not
accidentally change the settings for the other functions and tests.
Use a paper clip or other pointed object to set the switches.
1. Press the On Line button to take the printer off-line.
2. Turn the printer over and set the switches to the desired settings shown in
the table on the next page.
Switch 1 must be set to Off when setting switches for the RS-232C settings.
This puts the printer in the on-line mode to communicate with the host
system.
Caution: Do not set DIP switch 1 to On. Setting switch 1 to On puts the printer in
level 1 diagnostics (setup) mode where other functions and tests can be changed.

Parallel Switch Settings
The DIP switches are not used by the Parallel interface except for selecting the
size of the data buffer and for running diagnostic tests, which must be done while
the printer is in level 1 diagnostics (setup mode) with switch 1 set to On. See
“Level 1 Diagnostics” in the “Diagnostics” chapter for more information.
When switch 1 is set to Off, the printer is on-line and ready to communicate with
the host system. Switches 2-6 are not used at any time the printer is on-line, and
they are set to Off at the factory.
Caution: The switches can also be used for setting other functions and tests. Be
careful when setting the switches for the Data Buffer settings that you do not
accidentally change the settings for the other functions and tests.
Note: The Data Buffer option is set with the printer in the setup mode. See

Commands
Commands
The commands control all operations and functions of the 7193 printer, from
selecting the size and placement of characters and graphics on the receipt to
feeding and cutting the paper.
Note: All versions of the 7193 use the same commands as listed in this section
unless otherwise noted. For example, the Parallel interface does require unique
commands for controlling the cash drawer.
The 7193 commands emulate two printers: the NCR 7150™ Multifunction printer
and the Epson TM-T80™ Thermal printer. Any of the commands from either set
may be used in any combination to program a host system to communicate with
the 7193 (unless otherwise noted).
Some commands listed and described here are not implemented in the 7193 (they
are identified as not implemented). If received, they are ignored and not sent to
the print buffer as data. Non-legal commands are sent to the print buffer as data.

The values for n1 and n2 are two bytes in low byte, high byte word orientation.
Determine the value of n by multiplying the number of columns to move right of
the current position by 10 (standard pitch) or 8 (compressed pitch). The example
shows how to set the relative position two columns in standard pitch (10 dots per

Commands
7193 Owner’s Guide
Printer Status Commands
For RS-232C printers, these commands enable the printer to communicate with
the host system following the selected handshaking protocol, either DTR/ DSR or
XON/ XOFF. They are stored in the printer's data buffer as they are received, and
are handled by the firmware in the order in which they were received.
When a fault occurs, the printer will go busy at the RS-232C interface and not
respond to either of the Printer Status commands. If the fault causing the busy
condition can be cleared, such as by loading paper, or letting the thermal
printhead cool down, the printer will resume processing the data in its receive
buffer.
Printers manufactured after mid 1996 include Real Time commands which are
handled when the printer is busy at the RS-232C interface. See the following
section, “Real Time Commands,” for details about these commands.
Transmit Cash Drawer Status
Transmits current status of the cash drawers. One byte is sent to the host system.
This command is available only on RS-232 printers.
In DTR/ DSR protocol the printer waits for DSR = SPACE. If a drawer is not
connected, the status will indicate closed.

Commands
Real Time Commands
The Real Time commands correct difficulties with the original version of the 7193
RS-232C communication interface:
•
•
•
Real Time Status Transmission: GS (Hex 1D) Sequence and DLE (Hex 10)
Sequence
Real Time Request to Printer: GS (Hex 1D) Sequence and DLE (Hex 10)
Sequence
Real Time Printer Status Transmission
The original Printer Status commands, Transmit Printer Status (Hex 1B 76,
ASCII ESC v) and Transmit Cash Drawer Status (Hex 1B 75 0, ASCII ESC u 0)
are placed in the printer’s data buffer as they are received and handled by the
firmware in the order in which they were received. If the paper exhausts while
printing data which was in the buffer ahead of the status command, the printer
goes busy at the RS-232C interface and suspends processing the data in the buffer
until paper is reloaded. This is true for all error conditions: knife home error,
thermal printhead overheat, etc. In addition, there is no way to restart the printer
after a paper jam or other error.
The Real Time commands are implemented in two ways to correct these
problems. Both implementations offer the same functionality; which one you
choose depends on the current usage of your application.
First Implementation
For a new application the GS (Hex 1D) sequences of the first implementation are
recommended to avoid possible misinterpretation of a DLE (Hex 10) sequence as
a Clear Printer (Hex 10 0, ASCII DLE NUL) command.
The first implementation builds upon the GS ENQ sequence as implemented on
Epson’s TM-930II™, TM-950™ and TM-U950™ by defining two new GS (Hex
1D) sequences to provide the same functions as the DLE (Hex 10) sequences
above, and to provide complete backward compatibility to the original 7193 Clear
Printer command.
An application using these GS (Hex 1D) sequences does not need to distinguish
for the printer between the new Real Time commands and the old Clear Printer
command. This implementation is ideal for an existing 7193 application which
already uses the Clear Printer command or for a new application being
developed.
This implementation also provides the original GS ENQ Real Time sequence in
addition to the newer Real Time sequences.

Commands
7193 Owner’s Guide
Alternate Implementation
The alternate implementation uses the DLE (Hex 10) sequences as implemented
on Epson’s TM-T85™ and TM-U950™. An application using these DLE (Hex 10)
sequences and the original 7193 Clear Printer command must distinguish for the
printer between the new Real Time commands and the old Clear Printer
command by adding a NUL (Hex 00) to the Clear Printer command.
An application using these DLE (Hex 10) sequences must also send the second
byte of the sequence within 100 milliseconds of the first, to prevent the first byte
being mistaken for a Clear Printer command. This implementation is useful for an
existing TM-T85™ or TM-U950™ application which is being migrated to a 7193.
This application would not be using the 7193 Clear Printer command at all since
it is not recognized by the Epson printers.
Note: The DLE (Hex 10) sequences as implemented on Epson’s TM-T85™ and
TM-U950™ are not exactly the same as those implemented on Epson’s TM-950™.
This implementation also provides the original GS ENQ Real Time sequence in
addition to the newer Real Time sequences.
Rules for Using Real Time Commands
Three situations must be understood when using Real Time commands.
1. First, the printer executes the Real Time command upon receiving it and will
transmit status regardless of the condition of the DSR signal.
2. Second, the printer transmits status whenever it receives the Real Time status
transmission command sequence, even if that sequence happens to occur
within the data of another command, such as graphics data.
In this case the sequence will also be handled correctly as the graphics data it
is intended to be, when the graphics command is executed from the buffer.
3. Care must be taken not to send a Real Time command within the data
sequence of another command that consists of two or more bytes.
In this case the printer will use the Real Time command sequence bytes
instead of the other command’s bytes when finally executing that other
command from the buffer or the other command will not be executed
correctly.
These three situations generally preclude use of standard DOS drivers for the
serial communication ports when using Real Time commands.

Commands
Moving Data Through the Buffer
Applications should not let the buffer fill up with Real Time commands when the
printer is busy at the RS-232C interface. A busy condition at the RS-232C interface
can be determined by bit 3 of the response to GS ENQ or GS EOT 1 or DLE
EOT 1. The reason for a particular busy condition can be determined by other
responses to GS EOT n or DLE EOT n.
Although the printer responds to Real Time commands when it is busy, it will
place them into the buffer behind any other data there, and flush them out in the
order in which they were received. When the printer is busy due simply to buffer
full (that is, it can’t print data as fast as it can receive it), then data continues to be
processed out of the buffer at approximately print speed and the Real Time
commands will eventually get flushed out.
When the printer is busy due to an error condition, then data stops being
processed of the buffer until the condition clears one way or another. In either
case, but more quickly in the case of an error condition, the buffer can fill with
Real Time commands.
When the DLE sequences are being used, the last byte stored when the buffer fills
up could be the DLE code, with no room for the subsequent EOT or ENQ. When
this lone DLE byte is finally processed out of the buffer it will be interpreted as a
Clear Printer command.
Similarly, when the GS sequences are being used, the last byte stored when the
buffer fills up could be the GS code, with no room for the subsequent EOT or
ETX or ENQ. When this lone GS byte is finally processed out of the buffer it will
use the next byte, whatever it is, as the second byte in its GS sequence.
To guard against this situation, the application must determine the cause of a
busy condition and take appropriate action or pace the Real Time commands to
avoid filling the buffer. There are a minimum of 256 bytes available in the
printer’s buffer when it goes busy.

Busy Line and Fault Conditions
An additional improvement is made in the way the 7193 RS-232C handles the
busy line (or busy condition when using XON/ XOFF) during a fault condition.
Before this improvement, the printer would go busy at the RS-232C interface
when the receipt door was opened or the paper was exhausted as soon as it
received the next input byte. Bytes would continue to be accepted until the buffer
was full or the condition was cleared, but would stop processing data out of the
receive buffer. This resulted in the printer being unable to respond to the batch
mode status commands (ESC v and ESC u), or handle the cash drawer
commands even when it was not printing.
The improvement overcomes this limitation by not going busy at the RS-232C
interface until it attempts to process a command out of the receive buffer which it
can't do: for example, print on the receipt when it's out of paper. It will stay busy
and stop processing data out of the receive buffer until the condition clears.
Now if the cover is open or the paper is exhausted, the 7193 printer will still
accept data, respond to the batch mode status commands (ESC v and ESC u),
handle the cash drawer commands, and not go busy until it actually tries to
execute a print command. Then it will stay busy and stop processing data out of
the receive buffer until the condition clears. It will respond to the Real Time
commands as described below.
The only potential backward compatibility issue is if some application expects the
7193 to go busy when it processes a batch mode status command, which it now
won't. To handle this case, there is now a parameter setup in NVRAM to have the
printer handle the busy line the old way. The default will be the new way, but the
printer can be programmed in the field if it proves to be a problem.
To program the printer to handle the busy line the old way do the following
steps:
1. Record the current switch settings for their RS-232C parameters.
2. Set switches 2 and 3 to OFF, and set switches 1, 4, 5, and 6 to ON.
3. Power cycle the printer.
4. Wait until the printer beeps to store the parameter change in NVRAM.
5. Restore the switches to their RS-232C parameters.
6. Power cycle the printer.
7. Print out the diagnostics to be sure that the busy line parameter changed.

Recognizing Data from the Printer
An application sending various Real Time and non-Real Time commands to
which the printer responds can determine which command a response belongs to
by the following table. Responses to ESC u and ESC v are non-Real Time
responses and will arrive in the order in which they were solicited.
Note also that although the original intent of the response to ESC v was to
provide error information in its one-byte response, the response up to now has
always been Hex 00 when transmitted. This is because ESC v was not processed
until the error condition was cleared. With the improvement to the busy line
handling described earlier in this section, ESC v will be processed as long as there
is not an error condition caused by trying to print with no paper or with the
cover open.

Density of Receipt Print Lines
When the 7193 prints high density print lines (text or graphics), it automatically
slows down to a rate slower than 600 lines per minute. High density print lines
are defined as lines with over 57% of the dots printing on the line (there are 448
total dot columns on the print station).
Duty Cycle Restrictions (Printing Solid Blocks)
There are restrictions on the duty cycle because of the heat generated by the
receipt thermal printhead when printing solid blocks (regardless of the length of
the block in relation to the print line). The restrictions are ambient temperature,
the percentage of time (measured against one minute) of continuous solid
printing, and the amount of coverage.
Caution: When the duty cycle approches the limits shown in the table, the
receipt printhead will heat up and shut down. This may damage the printhead.
To avoid this problem, do one or a combination of the following:
1. Reduce the amount of coverage.
2. Reduce the time of continuous solid printing.
3. Reduce the ambient temperature.
