Setting the Binary
Communications Protocol
» Note: Binary communications protocol (BCP) is not available on
some printers. However, if it is available on your printer, the PS
Protocol menu appears in all interface menus. Check your printer
documentation for availability.
The PS Protocol menu allows you to set the binary communications
protocol (BCP) for communicating with a PostScript printer over the
CrownNet interface. BCP allows any 8-bit binary value (0-255) to be
treated as data, while still allowing a few of the values to function as
special control characters.

Choices Binary—Enables quoted binary communications protocol
(BCP) over serial and parallel interfaces. Print jobs can
change this setting through PostScript operators. Data in
the printable ASCII range also prints. Use the special
quoting mechanism (see the following section) for the
special characters and ^D (EOF).
» Note:
Binary provides only raw data, not quoted BCP,
over the CrownNet interface.
Binary Fixed—Enables binary communications protocol
(BCP). Print jobs cannot change this setting through
PostScript operators. Data in the printable ASCII range
also prints. Use the special quoting mechanism (see the
following section) for the special characters and ^D
(EOF).
» Note:
Binary Fixed provides only raw data, not quoted
BCP, over the CrownNet interface.
Normal—Enables standard, ASCII (7-bit) hex protocol over
serial, parallel, and CrownNet interfaces. 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 change this setting through PostScript operators.
