5.1.2.1 When the Power Supply Switch is Enabled

The TM printer is powered off when the power off command is sent from the application.

5.1.2.2 When the Power Supply Switch is Disabled

When the power off command is sent from the application, the POWER LED of the TM printer flashes, and the printer waits for the system power to be turned off. (“Error (ERROR) LED” on page F-2.)

Note:

While the printer is executing the power off process, do not reset the printer.

5.2 Head Divided Control

If a low capacitypower supply is used, you can specify 2-4 head divided control and eliminate the power supply for part of the dots to save current consumption. (The default setting is 1 head divided control which supply power to all dots at the same time.)

Print speed is slower if you increase the number of divisions.

ESC/POS commands allow you to change head divided control while printing. You can keep print speed by using the divided printing only when printing a high density area such as a logo.

5.3 Control After Paper Cut

When command control is used for printing, feed paper more than 1 mm {16/406"} immediately after paper cutting, and then stop feeding. 1 mm {16/406"} is equivalent to about 8 dots. If paper is left unfed after cutting, a paper jam may occur in the autocutter at the next paper feed.

5.4 NV Memory

The NV Memory of the printer can be roughly divided into 3 parts.

Firmware program area

NV memory area for product information. User cannot edit.

NV memory area that user can access.

The following items are in the NV memory that the user can access.

a)Memory switches

(Msw1, Msw2, Msw8, Customize value such as the paper width and Serial communication conditions.)

b)User NV memory

c)NV graphics memory
