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.

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).

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.

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.

May 1996


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.

Bottom of Printer

1. Remove the paper from the adhesive on the back of the pads or loop fasteners and affix them in the slots on the bottom of the printer.

2. Attach the hook fasteners to the loop fasteners (if used).

This will save you having to apply the hook fasteners separately and trying to match them to the loop fasteners on the printer.

3. Remove the paper from the adhesive on the back of the hook fasteners and place the printer firmly on the selected surface.

May 1996


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.

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.

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).

Solving Problems 7193 Owner’s Guide

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


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


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.

30 May 1996

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


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

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.

May 1996

Diagnostics 7193 Owner’s Guide


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.

The functions and tests are described in the following order in this section:

•

Setting Data Error (RS-232C only) and Data Buffer options

•

Setting printhead resistance

•

Setting default lines per inch

•

Level 2 diagnostics run during normal printer operation. When the following conditions occur, the printer automatically turns off the appropriate motors and disables printing to prevent damage:

•

Paper out, cover off, or knife unable to home

•

Printhead too hot or voltages out of range

The lights on the operator panel will signal when these conditions occur as well as indicate what state or mode the printer is in. See “Solving Problems” earlier in this book for a table describing the operator panel lights and for general troubleshooting information.


Level 3 diagnostics keep track of the following tallies and prints them on the receipt during the print test. See the sample test printout on page 24.

•

Number of lines printed

•

Number of knife cuts

•

Number of hours the printer has been on

May 1996


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.

May 1996

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.

46 May 1996

7193 Owner’s Guide 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.

Was an XON or XOFF charactor last received?

13 HEX

XOFF

Wait for

XON

11 HEX

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.

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


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.

Command List

This section groups the commands according to the following categories:

•

Printer Function Commands

•

Print Characteristics Commands

•

Graphics Commands

•

Printer Status Commands

•

Real Time Commands

•

Bar Code Commands

Within each group, the commands are listed in numerical order of their Hex codes. The page number refers to where a complete description of each command is given in the “Command Descriptions” section which begins on page 63.

Set Relative Starting Position

Moves the print starting position the specified number of dots either right (up to the right margin) or left (up to the left margin) of the current position.

The print starting position is reset to the first column after each line.


1B 5C n1 n2 27 92 n1 n2 ESC \ n1 n2 See Examples Below

To Move the Relative Starting Position Right of the Current Position

n = Number of dots to be moved right of the current position




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 column) to the right of the current position.

2 x 10 = 20 dots (two columns to be moved right of the current position)

20/256 = 0, remainder of 20

n1 = 20 n2 = 0

To Move the Relative Starting Position Left of the Current Position

n = Number of dots to be moved left of the current position

n1 = Remainder after dividing (65,536-n) by 256

n2 = Integer after dividing (65,536-n) by 256


Determine the value of n by multiplying the number of columns to move left 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 column) to the left of the current position.

2 x 10 = 20 dots (two columns to be moved left of the current position)

65,536-20 = 65516

These commands are used to enter and print graphics data and are described in order of their Hex codes:

Set Absolute Starting Position

Sets the print starting position for graphics at the specified number of dots from the beginning of the line as expressed in the following formula: n = ((n1 + (256 x

n2)) x 2). The resulting dot column must be less than 448. The print starting position is reset to column one after each line.

This command emulates the Epson LQ-950™ dot matrix printer. This allows the

7193 to accept graphics that are normally output from word processing programs to a half-dot matrix printer.

Hex

1B 24 n1 n2

Decimal ASCII

27 36 n1 n2 ESC $ n1 n2

Note: The 7193 converts two half-dots to one full dot



Set Bit Image Mode

Sets the print resolution and enters one line of graphics data into the print buffer.

Any print command is required to print the data, after which the printer returns to normal processing mode. See the illustrations for graphic representations of the bit image.

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.

Request Alternate Status

This command is available only on Parallel printers. It allows the printer to inform the host when the data in the buffer has been processed, compensating for the lack of bi-directional communication. Status information is limited to what can be sent by the dedicated lines: BUSY, ACK, PAPER EXHAUST, and FAULT.

When this command is sent to the printer, the printer goes “Busy” until all data which has been sent to the printer has been processed. The PAPER EXHAUST line shows the status for the cash drawer or receipt paper as follows:

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.

May 1996

Commands

88


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.

May 1996


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.


7. Print out the diagnostics to be sure that the busy line parameter changed.

May 1996


If you have programmed the printer to handle the busy line the old way, but wish to re-program it to the new way, do the following steps:

1. Record the current switch settings for their RS-232C parameters.

2. Set switches 2, 3, and 6 to OFF, and set switches 1, 4, and 5 to ON.


4. Wait until the printer beeps to store the parameter change in NVRAM.

5. Restore the switches to their RS-232C parameters.


7. Print out the diagnostics to be sure that the busy line parameter changed.

Restarts printing from the beginning of the line where an error occurred, after recovering from the error. Print settings that are normally preserved from line to line, such as character height and width, are still preserved with this command.

This sequence is ignored except when the printer is busy due to an error condition.

If the receipt is selected, this command will attempt recovery from a knife error.

Other errors associated with the receipt, such as paper out or printhead overheating, can be recovered from only by clearing the specific condition, such as loading paper or letting the printhead cool down.

n = 2

Recovers from an error after clearing the receive and print buffers. Print settings that are normally preserved from line to line, such as character height and width, are still preserved with this command. This sequence is ignored except when the printer is busy due to an error condition.

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.

If character code d cannot be printed, the printer prints the processed bar code data up to that point and the following data is treated as normal data. If the horizontal size exceeds one line, the printer does not print the excess data.

This command is enabled only when no data is in the print buffer. When data is in the printer buffer, the printer processes the data following ‘GS k I’ as normal data.

Condensation: Condensation may occur when the printer is moved from cold to warm areas after shipment. The printer's design permits operation after drying out and stabilizing at room temperature.

Print Zones

The printer centers characters (standard pitch and compressed pitch) and graphics on an 80 mm wide (3.15 in.) receipt.

•

Standard pitch: 10 x 18 dots in character cell, 44 characters (columns) per line

•

Compressed pitch: 8 x 18 dots in character cell, 56 characters (columns) per line

•

Graphics: 448 addressable bits

The minimum print line height is 18 dots for characters and 24 dots for graphics.

The standard print line height is 20 dots (3.33 mm, .131 in.) for characters (with two extra dot rows).

7193 Owner’s Guide Appendix A: Specifications

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.
