Explanation

This item appears only when I/O BUFFER=ON. Specify the amount of memory for I/O buffering. The maximum amount of memory available for I/O buffering is determined by the amount of memory installed in the printer, the languages installed in the printer, and by other memory allocations that must be made.

Press [-Value +] to change settings by increments of 10 (up to 100 KB) or by increments of 100 (above 100 KB).

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.

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.)

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 ROBUST XON item appears (see below).
