Table 3-11. I/O Menu (continued) Item Values Explanation PARALLEL HIGH SPEED=YES 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 FUNCTIONS=ON 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.) SERIAL PACING=DTR/DSR 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 ROBUST XON item appears (see below). Control Panel Menus 3-27
