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