Postscript I/O Mode

The PostScript I/O mode can be selected on a per Virtual Printer basis via the Web
menu:
Manage / System / Virtual Printer-><PS virtual printer>->PostScript->
PostScript I/O Mode / Raw, Normal, or TBCP
If printing binary data as PostScript job, select "Raw" mode for PostScript I/O Mode.

TBCP

In the TBCP mode the printer will recognize and process the special characters as
specified in the table below.
ASCII ASCII
KEYBOARD NAME
^A SOH
^C ETX
^D EOT
^E ENQ
^Q DC1
^S DC3
^T DC4
^[ ESC
^\ FS
The ^C special character causes an interrupt error. Data that follows a ^C character is
discarded until a ^D character is received.
The ^T special character causes PostScript to return its status via the back-channel. If
the PostScript interpreter is waiting for a job, the status string "%%[ status: idle ]%%"
is sent. If the PostScript interpreter is busy processing a job, the status string "%%[
status: busy; source: Network ]%%" is sent.
The ^D special character forces the end of PostScript job.
To transmit control characters as data, the host software must quote the character.
Quoting is done by replacing the character with the two-character sequence: ^A
followed by the character itself XOR-ed with 0x40. For example, to send a byte with
the hex value 0x14, the two-byte sequence 0x01 0x54 is sent.
All other special characters are ignored.
