*What is Right-Side-up Printing?
“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?
