Status and Error Messages
Printers return PostScript emulation error messages and status information to the
computer through any active interface. To send information to the computer through
the parallel interface, configure the interface as bidirectional.
Tagged Binary Not Active
Your printer responds and processes a Ctrl+T (x'14') command as a status query
when:
• The PostScript emulation interpreter is processing a print job.
• The printer is idle and the PostScript emulation interpreter is the selected
interpreter.
Your printer responds and processes a Ctrl+T (x'14') command as normal data and
not a status query when:
• Another interpreter is processing a print job.
• The printer is idle and another interpreter is the selected interpreter.
Notes:
• Status queries cannot be received while the printer is in an error state.
• Your printer always selects the PostScript emulation interpreter and pro-
cesses a Ctrl+T (x'14') command as a status query when data is received
through the LocalTalk interface.
Tagged Binary Active
When Tagged Binary is active, your printer always responds to a Ctrl+T (x'14')
command as a status query and selects the PostScript emulation interpreter to
process the current print job. Tagged Binary mode is immediately exited at the end of
the print job.
Note: Status queries cannot be received while the printer is in an error state.
