Confidential 1 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. (See "Forbidden/Restricted commands for right side up printing mode" on page 8.) • 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: 4KB) to be turnedon. • The right side up printing mode is provided for Type B (ANK) and Type D (ANK) models only. Type A or Multilingual models don't have this printing mode. Note: When you use this method, don't turn on DIP switch 1-1.
