Application Development Information

Development Environment

The following three methods are available for developing applications for a TM printer.
EPSON OPOS ADK
EPSON OPOS ADK uses OCX controls customized for POS application development.
EPSON Advanced Windows Driver
Using Windows driver, printing from applications is available as other general printers.
ESC/POS commands
Using ESC/POS commands, TM printer can be controlled directly.

Power Supply Off with POS Command

Turning the power on and off with the front switch is disabled when DIP switch 1-1 is set to on.
In this case, a POS command is used to turn the power off. See page 3-2.

Paper Layout

By storing paper type (label paper, receipt paper, receipt paper with black mark and label paper
with black mark) and vertical layout (label length, distance between black marks) to NV (non
volatile) memory, you can decrease wasteful paper feed and shortening of time for initializing
(power on, cover close, recover from error). This setting is called "paper layout setting". Set
"paper layout setting" as needed.

Case 1: When you use a specific kind of paper continuously

The initialization time shortens when "paper layout setting" is done, and improve ease of
usage. There are three kinds of methods of "paper layout setting".
Setting method 1:
Automatically setting is done only by TM-L90 operation. (Refer to page 3-14 * Except label
paper with black mark.
Setting method 2:
Automatically setting is done by transmitting "GS ( A". Except label paper with black mark.
Note:
If "paper layout setting" is stored in NV memory in advanced, need to transmit GS ( E (Function 48)
with state of inserting stored paper.
