PPDS Compatibility

PPDS is supported in Native 4247 mode and in IBM 2381 Personal Printer and IBM
4202 Proprinter III XL emulation modes. When Native 4247 mode is selected,
PPDS control codes are supported in the same manner as if emulating the IBM
2381 Personal Printer. The emulation mode can be selected from the Program
Configuration menu, using the operator panel. Emulation mode also may be
selected using the Set Initial Conditions (ESC [ K) control sequence, if the printer is
set to Native 4247 or 2381 emulation mode.
