The printer MIBs have a bunch more things in them than supplies status - and allowing printer herders to see status of covers, trays and other things on the Fusioninventory GLPI page solves the issue of needing multiple interfaces to monitor the things.
It means the staff tasked with monitoring printers can see what many issues are before they leave their desks (we poll the printers every 15-20 minutes) and if someone who isn't supposed to has their hands inside one of the machines (which is a major problem in a university environment - We've found major damage to parts at times)
It's actually fairly important to be able to monitor paper trays - if we don't load paper when (or slightly before) it runs out then users try to do it themselves and it's surprising how many "wrong" ways they can find to do it (paper has a natural curl and if you put it in the wrong side up, it will jam more frequently)
Here are a few extremely useful OIDs worth monitoring:
1.3.6.1.2.1.43.9.2.1.1 (prtOutputIndex): output capacity (0 or more; 0 means out of paper)
1.3.6.1.2.1.25.3.5.1.2 (hrPrinterDetectedErrorState): octet string of
length 2 (2 bytes); if bits below are set, corresponding error condition is in effect:
lowPaper 0

If both bytes are zero, no error condition detected.

Here are a few extremely useful OIDs worth monitoring:
.1.3.6.1.2.1.43.6 - prCovers
Examples:
HP Laserjet 4100 and CLJ5500 (most HP laserjets)
Kyocera P6021 Color printer
Kyocera Taskalfa (MFP)
.1.3.6.1.2.1.43.8 - prInputs - this one needs to be a little selective, as you really only want to know the status of the trays and what's in them.
Kyocera TaskAlfa:
HP LJ 4100
HP CLJ 5500
Kyocera P6021
 prtOutput 1.3.6.1.2.1.43.9 - output trays
Kyocera P6021
LJ4100 & CLJ5500
Kyocera Taskalfa
