I/O Setup

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

TBCP

In the TBCP mode the printer will recognize and process the special characters as specified in the table below.

ASCII	ASCII	VALUE	CONTROL FUNCTION	PRINTER BEHAVIOR
KEYBOARD	NAME	(HEX)
^A	SOH	0x01	Quote data character	See Control Function
^C	ETX	0x03	Generate an interrupt error	See Control Function
^D	EOT	0x04	End of file marker	See Control Function
^E	ENQ	0x05	Reserved	Ignored
^Q	DC1	0x11	XON in XON/XOFF flow control	Ignored
^S	DC3	0x13	XOFF in XON/XOFF flow control	Ignored
^T	DC4	0x14	Job status request	See Control Function
^[	ESC	0x1B	Start of end protocol sequence	See Control Function
^\	FS	0x1C	Reserved	Ignored

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.
