softwareiomode
Syntax | int setsoftwareiomode – |
Definition This operator sets the binary protocol mode of the communications channel according to the value of int:
0binary protocol off
100binary protocol on
Binary protocol is standard in the LaserWriter Select 310 printer, and it should be used by any driver that sends binary data to the printer.
A driver that does not use the binary protocol and does not filter the back channel data when softwareiomode is 100 will see receive control characters as quoted characters. In particular,
The softwareiomode operator does not need to be set outside the server loop in order to be compatible with other printer implementations of sofwareiomode. However changes to it do not take effect until the job that makes the changes is completed.
Standard value: 100
