Note:

A separate USB device driver is required for a USB model printer, and a separate IP setup utility is required for an Ethernet model printer. See the manual packed with the APD.

When you use the APD for the TM-T88IV, using TrueType fonts may slow printing down, due to the speed of communication between the printer and host computer. If this happens, we recommend using printer-resident fonts. For details on how to use resident fonts, see the user's manual for the APD.

Printing with TrueType fonts on other interfaces may have a slight influence on customer applications. In that case, use the printer-resident fonts. Because of the restrictions of some customer applications, when the APD is used with that application, resident fonts sometimes cannot be used, even if they are specified.

When OPOS is used, this problem does not arise because only the printer-resident fonts are available.

3.3.3.1 Error Codes

There are three possible error types: automatically recoverable errors, recoverable errors, and unrecoverable errors.

❏ For automatically recoverable errors, the user does not have to take any action. The error

recovers automatically when the head temperature returns to normal or the cover is correctly closed.

❏ A recoverable error recovers by resetting the printer or sending a command from the driver

after the cause of the error is eliminated.

❏ For unrecoverable errors, the printer or the power supply may be malfunctioning and must

be repaired.

Automatically recoverable errors

Although normal printer operation is no longer possible when automatically recoverable errors occur, they do not represent printer failure. They can be recovered easily, as described below.

Note:

The error recovery command is valid only if a recoverable error (excluding automatically recoverable errors) occurs. If a recoverable error occurs, the printer recovers from the error upon receipt of an error recovery command from the driver after the cause of the error is eliminated. Turning the printer’s power off and on is not required.

Unrecoverable errors

Normal printer operation is no longer possible when unrecoverable errors occur. The printer must be repaired.

3.4 Sensors

3.4.1 Paper Sensors

The printer has two paper sensors.

3.4.1.1 Roll paper near-end sensor

The roll paper near-end sensor uses the diameter of the roll paper to detect whether the remaining paper is getting low. This sensor is located inside the roll paper supply unit, and you can fine-tune the amount of remaining paper detected by this sensor. (For details on adjustment, see page 2-6.)

Lighting of the PAPER OUT LED in a near-end state does not indicate an error. Regular printing is possible.

Note:

Detection of the near-end status does not necessarily indicate the complete end of the roll paper. Use the sensor as an indication of when to replace the roll paper.

By changing the driver setting, a print job can be canceled automatically during the near-end status.

3.4.1.2 Roll Paper End Sensor

The roll paper end sensor detects whether there is paper in the paper path. When there is no paper (paper end status), the PAPER OUT LED and ERROR LED light to indicate an error has occurred. If the sensor detects a roll paper end, the printer stops printing, even in the process of printing. We recommend that you mainly rely on the roll paper near-end sensor and use the roll paper end sensor secondarily.

3.4.2 Printer Cover Sensor

3.4.2.1 Roll Paper Cover Open Sensor

The cover-open sensor monitors the roll paper cover. When the sensor detects an open cover during printing, the printer stops printing immediately and automatically goes offline.

This status is treated as an automatically recoverable error, and the ERROR LED flashes. When the printer cover is closed, the ERROR LED goes out, and the printer goes online and starts printing at the beginning of the line it was printing when the cover was opened.

When the printer recovers, it feeds paper to take up slack and starts printing from the beginning of the line where the error occurred. In this case, double printing and printing position shift may occur. When a cover open error occurs, we recommend clearing the printer’s print buffer by sending the error recovery command from the driver, and resending the print data.

Note:

Whether the cover is open or not does not affect the status reported by the roll paper end sensor.

3-10 Application Development Information Rev. A

TM-T88IV Technical Reference Guide

3.4.3 Offline

This printer is not equipped with an online/offline switch. The printer automatically goes offline under the following conditions:

• During power on (including resetting with the interface) until the printer is ready

• During the self-test

• When the roll paper cover is open

• During paper feeding using the FEED button

• When the printer stops printing due to a paper-end (if an empty paper supply is detected by the roll paper end sensor or if the driver has been set to stop printing when a roll paper near-end is detected)

• When an error has occurred

• During macro executing standby status

3.4.4 Busy State

3.4.4.1 Selecting conditions for invoking a BUSY state

With DIP SW2-1, you can select conditions for invoking a BUSY state as either of the following:

❏ When the receive buffer is full

❏ When the receive buffer is full or the printer is offline

Note:

In either case above, the printer enters the BUSY state after power is turned on (including resetting with the interface), while the printer is in the standby state waiting for data, and when a self-test is being run.

For details on how to change the DIP switch setting for receive buffer full, see “Setting the DIP Switches” on page 2-2.

When using the Advanced Printer Driver, DIP SW2-1 must be ON. When using OPOS, it can be either ON or OFF.

3.5 NVRAM (Non-volatile Memory)

NVRAM is mounted on this printer, and bitmap images (for example, business logos) or other data are written to it. Pay attention to the following when using NVRAM.

❏ The following restriction applies when performing operations (including storing and

deleting data) in NVRAM.

• Do not use the FEED button.

❏ The printer sometimes enters the BUSY state when data is being written to NVRAM. It is

important not to send data from the host computer while the printer is in the BUSY state, because the printer cannot process any received data.

❏ Frequent use of the functions for writing data to and deleting data from NVRAM may

damage the memory. As a rule, in using the various commands to write to NVRAM, avoid writing more than an average of ten times per day.

3.6 Bar Code Printing

This printer can print the following types of bar codes:

UPC-A, UPC-E JAN 8 (EAN 8), JAN 13 (EAN 13) CODE 39 ITF (Interleaved 2 of 5) CODABAR (NW-7) CODE 93 CODE 128 PDF417 (2D code ) QR Code

To set and print each bar code, refer to the OPOS, Advanced Printer Driver, and ESC/POS command documentation, respectively.

Note:

Take a consideration as described below to determine whether the ability of the reader (scanner) can be satisfied when the print result on the receipt, such as bar code, 2-dimensional code, or characters.

• Print density The print density may vary depending on the type of roll paper or the environmental conditions.

3-12 Application Development Information Rev. A

TM-T88IV Technical Reference Guide

3.7 Notes on Printing 2-Dimensional Code

The TM-T88IV supports 2-dimensional code printing. Be sure to follow the notes below when printing 2-dimensional codes.

• When printing PDF417 (2-dimensional code), it is recommended to set the height of one module of the symbol to three to five times the width of one module, also making sure that the total height is almost 5 mm {0.20"} or more.

• The recognition rate of the 2-dimensional code may be affected by such items as different widths of the modules, print density, environmental temperature, type of the thermal paper, and characteristics of the reader. Therefore, the user should check the recognition rate in advance so that the limitations of the reader can be considered.

3.8 Two-color printing

For selecting colors/how to print, see the relevant documents for OPOS, the printer driver, and the ESC/POS commands.

3.9 Operating Mode (Switch Panel Operation)

host computer and printer is not performed correctly. This can result in errors related to print buffer size.

3.10.1.1 Corrective procedure

1. Check the serial communication cable, and check the cable connector specifications. (See “Serial Interface Connection” on page 2-8.)

2. Check the serial communication conditions of the printer and the host.

Serial communication conditions

• Baud rate

•Parity

•Flow control

•Data length

You can check printer settings as follows:

1. Run a self-test to check the printer’s serial communication conditions. (See page 3-13.)

2. Setting communication conditions using the DIP switches. Set the baud rate with DIP

SW1-7 and SW1-8. (Refer to page 2-4.)

3.10.2 Q: Why does the drawer kick-out not operate properly?

A: Drawer specifications differ depending on the manufacturer and the part number. Make

sure the specifications of the drawer to be used meet the following conditions before connecting it to the drawer kick-out connector. These conditions also apply to any other devices that use the drawer kick-out connector. Any devices that do not satisfy all the following conditions must not be used.

Conditions

• A load must be provided across drawer kick-out connector pins 4 and 2 or across pins 4

and 5. (*1)

• When the drawer open/close signal is used, a switch must be provided across drawer

kick-out connector pins 3 and 6. (*2)

• The solenoid used for the cash drawer must have a resistance of 24 Ω or higher. (*3)

3-14 Application Development Information Rev. A

TM-T88IV Technical Reference Guide

NOTES

(*1) Operating the printer with incorrectly installed devices voids the warranty. (*2) Connecting devices other than the drawer open/close switch voids the warranty. (*3) Using a drawer or a drawer kick-out connector with an input current of 1 A or more may cause an

over current, which will cause the device to malfunction.

3.10.3 Q: I cannot print part of Page 0 in Visual Basic. Why?

Cannot print a part of Page 0 (for example: ) in Visual Basic.

A: Try printing using the following procedure:

When programming with Visual Basic, limitations prevent data from 81H through 9FH and from E0H through FEh from being sent as characters. However, you can use the following procedure to send this data:

Dim Send_ data(0) As Byte Send_data(0) = &h81 ’1 byte of sending data MSComm1.Output = Send_data

ESC/POS Command-related Information

This chapter introduces the printer operation settings, which can be made by using ESC/POS commands, and precautions for those operation settings.

4.1 NV Memory (Non-volatile Memory)

The printer’s NV memory can be roughly divided into three parts:

• Firmware program area

• NV memory area for product information (This area cannot be edited by the user.)

• NV memory area that the user can access

The following areas are in the NV memory that the user can access:

• NV user memory

• NV graphics memory

• User-defined character code page (“C.11 Page 255 (Blank Page)”)

• Area of user-defined command default values

You can customize your printer by changing these values. Note the following when writing to and deleting from NV memory.

❏ The following restrictions apply when performing non-volatile memory operations

(including data writing and deleting).

• Do not press the FEED button.

• Do not execute a real-time command.

• The ASB status is not sent, even when the ASB function in ESC/POS commands is set to Enabled.

❏ The printer sometimes enters the BUSY state while data is written to NV memory. It is

important not to send data from the host computer while the printer is BUSY, because the printer cannot process any received data.

❏ Frequent use of the functions for writing data to and deleting data from NV memory may

damage the memory. As a rule in using the various commands to write to NV memory, avoid writing more than an average of ten times per day.

4.1.1 Using NV Memory

You can use the free area in NV memory for writing memos, for other character information, for anything you like. Data written to this area is held in the memory even if you turn off the power. For details on how to read and write data, see the “ESC/POS Application Programming Guide.”

Rev. A ESC/POS Command-related Information 4-1

Note:

For details on NV graphics and NV bit images, see the “ESC/POS Application Programming Guide.”

4.2 Printer Status

There are three ways to get the printer status, and each method has the following features. For details, see the “ESC/POS Application Programming Guide.”

• Automatic status back (ASB): When a status request is processed as a regular command, the printer automatically returns a status message whenever the status changes. Always monitor the value returned.

•Real-time status: When the printer receives a real-time status command, it responds with the specified printer status. Returning the printer status takes priority over any regular print data.

•Status: The printer transmits a specified printer status in the same way it processes normal print data.

4.3 Precautions When the Printer Is Offline

When printer handshake is set with DIP SW2-1 ON (BUSY = receive buffer full), use the ASB function to check the printer status. Using the ASB lets the printer send status automatically at the time of switching online/offline. When using a real-time command, make sure the receive buffer is not full.

Example: After using the 4KB receive buffer to send data for each line, check the printer status.

4.4 Outputting Hex Dumps

TM printers can print data transmitted from the host computer as hexadecimal numbers and their corresponding characters. Called “hex dump mode,” this allows you to make sure that data has been sent correctly to the TM printer by comparing the printed result with the program. Follow the steps below to output a hex dump:

1. With the roll paper cover open, turn power on while holding down the FEED button.

2. Close the roll paper cover.

3. Data received from then on is printed out from the TM printer in hexadecimal numbers and their corresponding characters.

To quit the hex dump mode, turn the printer off or press FEED button three times.

Note:

Do not use this mode when using OPOS or the APD. Doing so will cause unexpected data to be printed, because the driver uses proprietary control to drive the printer.

SPACE indicates that the host computer can receive data.

MARK indicates that the host computer cannot receive data. When DTR/DSR control is selected, the printer transmits data after confirming this signal (except if transmitted using some ESC/POS commands). When XON/XOFF control is selected, the printer does not check this signal. Changing DIP SW2-7 lets this signal be used as a printer reset signal. When you use this signal as the printer’s reset signal, the printer is reset when the signal remains MARK for a pulse width of 1ms or more.

SPACE status — indicates the printer is ready to receive data. MARK status — indicates the printer is Busy. Set Busy conditions with DIP SW2-1. (Refer to “Busy State” on page 3-11).

2) When XON/XOFF control is selected, the signal indicates that the printer is

properly connected and ready to receive data from the host. SPACE status — indicates the printer is properly connected and ready to receive data from the host. The signal is always SPACE, except in the following cases:

• During the period from when power is turned on to when the printer is ready to receive data.

• During the self-test.

The printer is reset if the signal remains at SPACE for a pulse width of 1 ms or more.

A.1.3 XON/XOFF

When XON/XOFF control is selected, the printer transmits the XON or XOFF signals as follows. The transmission timing of XON/XOFF differs, depending on the setting of DIP SW2-1.

Rev. A Interfaces and Connectors A-3

Reverse mode

The transfer of status data from the printer to the host proceeds in the nibble or byte mode.

This mode allows data transfer from an asynchronous printer under the control of the host. Data transfers in the nibble mode are made via the existing control lines in units of four bits (a nibble). In the byte mode, data transfer proceeds by making the 8-bit data lines bidirectional. Both modes fail to proceed concurrently in the compatibility mode, thereby causing half-duplex transmission.
