ESC/POS Command-Related Information
This chapter introduces the printer operation settings that can be made with ESC/POS
commands and their precautions.

5.1 TM Printer Operation Performed When Power Supply Switch is Disabled

When the power switch is disabled with the DIP switches (refer to "DIP Switch Settings" on
page 2-21), the power switch is always on. In other words, the power of the TM printer is on
when power is supplied, and is off when power is not supplied by the system.
When the power supply switch is disabled, the TM printer is reset by pressing the power switch
more than 3 seconds. This is true for both recoverable and unrecoverable errors.
When the power supply switch is disabled, a software power off preparation process must be
executed for the TM printer from the application before the power supply is turned off. When
the power supply switch is disabled, main power does not turn off and the POWER LED flashes
if a software power off process is executed.
* Power off process: The TM printer stores the latest TM printer condition before power down. Refer to the ESC/POS
