Setting the Memory Switches

With the “memory switch (customized value”), which is a software switch of this printer, you

can set:

•Print density

•Print speed

•Number of head energizing parts

Use the Memory Switch Setting Utility or a command to set the memory switches.

• For detailed information about the memory switch utility, see the user’s manual for the Memory Switch Setting Utility.

• For detailed information about ESC/POS commands, see the ESC/POS Application Programing Guide.

Selecting the print density

Selectable from levels 1 to 13 (light ∼ dark).

The print density can be set with DIP switches (2-3/2-4) or the customized value. (See

"Setting the Memory Switches" on page 38.) The initial setting of the customized value is

“Depends on the DIP switch settings.” If the customized value is once changed, value set with the customized value is enabled.

Selecting the print speed

Selectable from levels 1 to 9 (low ∼ high). (Initial setting: level 9)

Depending on print conditions such as print duty, print head temperature, or data transmission speed, print speed is automatically adjusted which may cause white lines due to intermittent print (the motor sometimes stops). To avoid this, keep the print speed constant by setting it lower, or set the transmission speed higher in case of the serial interface. (See "Transmission speed (DIP switch 1-7/1-8)" on page 33.)

Selecting the number of head energizing parts

•One-part energizing

•Two-part energizing

•Four-part energizing

•Auto energizing (Initial setting)

Usually, the number of head energizing parts does not need to be changed.

Chapter 3 Application Development Information

Application Development Information

This chapter describes how to control the printer and gives information useful for printer

application development.

How to Control the Printer

Use a driver or ESC/POS commands to control the printer.

Selecting a Driver

Choose one of the drivers, Advanced Printer Driver (APD) or OPOS ADK, depending on the

application operating environment. You cannot control the same printer with both of the drivers.

For information about the driver operating environment, see the installation manual for each

driver.

When you newly develop an application

•Use APD if you want to print TrueType fonts or print much graphics.

•OPOS ADK is recommended for system extensibility. A n OPOS driver is provided for various

peripherals and it is now a POS industry standard. It enables efficient POS system

establishment, reduction of development cost

, and effective use of application assets.

When APD is used for your existing application

Use APD.

When OPOS ADK is used for your existing application

Use OPOS ADK.

You can use all functions including ones not supported by OPOS ADK or APD by using a driver with ESC/POS commands. Use the DIRECT I/O function of OPOS ADK, the control A command of APD, or Status API to send ESC/POS commands from each driver. (See "ESC/POS command functions" on page 52.)

51

ESC/POS Command

ESC/POS is the Epson original printer command system. With ESC/POS commands, you can

directly control all the TM printer functions, but detailed knowledge of printer specifications or

combination of commands is required compared to using a driver.

To use ESC/POS commands, you need to make a nondisclosure cont

ract first and get the

ESC/POS Application Programing Guide. Ask your dealer for details.

The ESC/POS command functions are listed as follows. See the ESC/POS Application

with DIP switch 2-1.

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

25 INT Input Changing DIP switch 2-8 enables this signal to be

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

66

Appendix

XON/XOFF

When XON/XOFF control i s selected, the printer transmits the XON or XOFF signals as follows.

The transmission timing of XON/XOFF differs, depending on the setting of DIP switch 2-1.

DIP switch 2-1

Signal Printer status

1 (ON) 0 (OFF)

XON 1) When the printer goes online after turning on the power (or

reset using the interface)

2) When the receive buffer is released from the buffer full state Transmit Transmit

3) When the printer switches from offline to online — Transmit

4) When the printer recovers from an error using some ESC/POS commands

XOFF 5) When the receive buffer becomes full Transmit Transmit

6) When the printer switches from online to offline — Transmit

Transmit Transmit

—Transmit

Code

The hexadecimal numbers corresponding to the XON/XOFF codes are shown below.

• XON code: 11H

•XOFF code: 13H

• When the printer goes from offline to online and the receive buffer is full, XON is not transmitted.

CAUTION

• When the printer goes from online to offline and the receive buffer is full, XOFF is not transmitted.

• When DIP switch 1-3 is off, XON is not transmitted as long as the printer is offline, even if a receive buffer full state has been cleared.

IEEE 1284 Parallel Interface

Modes

The IEEE 1284 parallel interface supports the following two modes.

Mode Communication direction Other information

Compatibility mode Host → Printer communication Centronics-compliant

Reverse mode Printer → Host communication Assumes a data transfer from an

asynchronous printer

Compatibility Mode

Compatibility mode allows data transmission from host to printer only: Centronics-compatible.

Specification

Data transmission 8-bit parallel

Synchronization Externally supplied STROBE signals

Handshaking ACK

Signal levels TTL-compatible connector

Connector ADS-B36BLFDR176 (HONDA) or equivalent product

Reverse communication Nibble or byte mode

and BUSY signals

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

fail to proceed concurrently in the compatibility mode, thereby causing half-duplex

transmission.

transfer proceeds by making the 8-bit data lines bidirectional. Both modes

Status transmission from printer with USB interface

In order to ensure that there is no lack of status data, it is necessary to periodically retrieve status

data at the host computer.

Unlike RS232C transmission, it cannot spontaneously interrupt data transmission

computer.

The printer has a 128-byte status data buffer. Statuses that exceed the buffer capacity are

cancelled.
