The only problem I can see with SNMP is that it doesn't allow the
kind of accounting offered by PrintBill, which keeps records about
ink coverage in all colors. PostScript and paper jams problems apart, this provides fair accounting for people who print mostly black text
wrt people who always print their family color pictures...
I've done some testing with retrieving ink levels from SNMP enabled printers (I've only got two very similar HPs, 2100 and 2200, unfortunately) but this is not precise enough : "full", "low", "middle" is the sort of thing I get.
Xerox Phaser printers do job accounting of the percentage of each color supply, and even the maintenance kit, to a ridiculous number of decimal places - all accessible via SNMP.
The good thing about this is that somebody who is printing text doesn't have to pay the same rate as somebody who is printing a full coverage image.
The bad thing is that nobody knows what they are going to be charged ahead of time.
We don't use it at the moment.
