Communications
2-23 Printer Configuration
Setting Parallel Interface Parameters
Use the Administration/Communications/Parallel menu to set the par-
allel interface values used for printer-host communications.
Mode
The parallel interface supports Centronics parallel communication as
well as IEEE 1284 bidirectional parallel communication.
Choices Normal—Enable standard, ASCII hex protocol. Data is sent
and received in ASCII format. This mode is recommended if
you do not print binary data. It was designed for data in the
printable ASCII range. Print jobs can alter the PS protocol
value through PostScript operators.
Normal Fixed—Enable standard, ASCII hex protocol. Print
jobs cannot alter this value through PostScript operators.
Binary—Enable Quoted binary communications protocol. Print
jobs can alter this value through PostScript operators. Data in
the printable ASCII range also prints.
Binary Fixed—Enable Quoted binary communications
protocol. Print jobs cannot alter this value through PostScript
operators. Data in the printable ASCII range also prints.
Default Normal
Notes See chapter 5, “Additional Technical Information,” for a full
discussion of PS Protocol.
