“Right-side-up printing“ is a printing mode for printers installed on a
wall. It reverses the printing result by buffering print data.
However, the right side up printing mode has the
following limitations:
-
The right side up printing mode is for control
with ESC/POS commands. The mode is not supported by any driver (OPOS
and Advanced printer driver [APD]) or utility software.
-
Some ESC/POS commands have restrictions during
Right side up printing.
-
The right side up printing mode has no guarantee
at “receive buffer full.“ Therefore, host PC should have a
control to prevent it.
-
The right side up printing mode requires DIP
switch 1-2 (receive buffer: 4/16KB) to be turned on.
How does the printer print in the right side up printing
mode?
