3.4.3 Memory Switches

This printer has "Memory switch" set which is software switches. Memory switch set has "Msw
2," "Msw 8," "Customize value," "Serial communication condition."
"Memory switch setting utility" can change the Memory switch set to ON or OFF as shown in
the table below (default: all OFF):
Note:
The Memory switch is available to be changed by five methods:
• Memory switch setting utility
• Memory switch setup mode (there are limitations on what can be changed)
• Control from setupPOS (OPOS only, and there are limitations on what can be changed)
• Control from Windows driver (Advanced Printer Driver only, and
• Control from ESC/POS command
Some Memory switch settings can be changed by the "Memory switch setting mode."See "Memory
Switch Setup Mode" on page 3-19.
Settings of the memory switch are stored in the NV memory; therefore, even if the printer is turned off, the
settings are maintained. Excessive use of this function may destroy the NV memory. As a guideline, do
not use this function more than 10 times a day.
When you use OPOS or APD, generally you don't need to adjust memory switch because OPOS or APD
are able to set these items automatically.
When you replace a TM-U210 with a TM-U220, you should adjust the Msw 8-5 to OFF.
