ed from the power OFF.
Pressing the POWER button while the state of USB-linked power OFF turns on power nor-
mally.
Paper saving functions
Memory switches MSW8-3 through MSW8-4 can be used to congure the settings
below, which save paper.
Top margin suppression
The printer back feeds the paper before printing which reduces the blank space
at the top edge of the paper.
The back feed amount can be specied.
Line gap reduce
Automatically compresses the linefeed amount between lines. The compression
ratio can be specied.
CAUTION
Remove the partially cut paper before performing back feed for starting printing.
The cut paper may be torn off in the next printing process, which may cause a problem.
 Auto side shift (MSW8-6)
This function dissipates heat load during frequent heat generation by a vertical
ruled line or other specic head heating element.
If no data is received within 15 seconds after each cut or print, the print position is
automatically slid N* dots to the right. The original print position is returned to at the
next slide timing.
* N is the MSW8-6 setting value.
CAUTION
If the right margin is too narrow, this may result in some print characters being cut off.
This function is disabled under initial settings.
To enable this function, use MSW8-6 to specify an appropriate value for the maximum slide
amount.
