Status Messages

Your printer responds to a Ctrl-T (x'14') status query on an interface by sending a
one-line status message back to the host computer over the same interface. If the
status query is received between print jobs and the printer is idle with no error
conditions, an idle response is returned to the host computer.

Status messages are bracketed by the characters

%%[

and

]%%

, so the computer

software can extract them from other data generated by the current print job. They
follow a standard syntax, consisting of one or more key-value pairs, separated by
semicolons. For example:

%%[

job: Project Report; status: busy; source: Parallel

]%%

The following table lists the possible keys and value descriptions.

To determine which status message keys your printer supports, see Table C-7 on
page C-23.
