SNMP runs over UDP. The network security issues can be hideous or
trivial, depending on the approach you take.
If you use SNMP, then you have to fight through the various OIDS,
and then make sure that the values you get for 'end of job' really
do match the 'end of job'. You also have to make sure that the
Pagecounter value is really the right value.
If you use PJL/Postscript, then you have to fight through the various PJL
insanities, and hope that PJL Echo, PJL JOB/END, etc., work.
If you are using USTATUS, then you need to make sure that you
really do get status :-) You also have to make sure that the
Pagecounter value is really the right value.
It is a case of death by fire or death by water.
