Explanation

PARALLEL HIGH

YES

SPEED=YES

NO

Select the speed at which data is transmitted to the printer.

YES: The printer accepts faster parallel communications used for connections with newer computers.

NO: The printer accepts slower parallel communications used for connections with older computers.

PARALLEL ADV

ON

FUNCTIONS=ON

OFF

Turn the bidirectional parallel communication on or off. The default is set for a bidirectional parallel port (IEEE-1284).

This setting allows the printer to send status readback messages to the computer. (Turning on the parallel advanced functions might slow language switching.)

SERIALDTR/DSR

PACING=DTR/DSR XON/XOFF

Select the type of pacing used. Pacing, or “handshaking” allows the printer to tell the computer when to send information. The printer uses XON/XOFF and DTR/DSR signal protocols rather than ETX/ACK protocol.

DTR/DSR: Select this value if your computer requires hardware flow control (most personal computers do).

XON/XOFF: Select this value if your computer requires software flow control (a UNIX workstation, for example). The SERIAL
