;'5

Select the speed at which data is transmitted

to the printer.

 

 

;'5: The printer accepts faster parallel

 

 

communications used for connections with

 

 

newer computers.

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

 

 

the parallel advanced functions on might slow

 

 

language switching.)

“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.

 

 

&64￿&54: Select this value if your computer

 

 

requires hardware flow control (most personal

 

 

computers do).

 

 

:10￿:1((: Select this value if your computer

 

 

requires software flow control (a UNIX

 

 

workstation, for example). The 5'4+#.￿

generating XONs.

10: The printer sends an XON when the printer is online and when sufficient buffer space is available. If the host does not receive data within approximately one second, the printer will transmit additional XONs at one second intervals until the host receives data.

1((: The printer sends one XON when it can accept more data or when it is online. The printer does not send XONs every second while the printer is online and ready for more data.
