*****************
|
|
|
|
PRINTER COMMS:
|
|
|
|
* Strip out "JOBSIZE=" headers
|
|
* Send PJL header
|
|
* Send PDL payload
|
|
* Send PJL footer
|
|
|
|
PJL header and footer need to be sent separately.
|
|
the PJL wrapper around the PDL block needs to be
|
|
stripped. A footer seems to be needed at the end of the PDL block.
|
|
Another unknown footer seems to be sent before
|
|
|
|
No idea about actual printer communications, but it's likely that
|
|
printers use PJL "alerts" to get updates about active jobs, and
|
|
that other stuff can be queried via standard means.
|
|
|
|
Further progress will have to wait until I get access to
|
|
one of these models.
