Here are the below OIDs we use to get the status of the printer which are hard coded in OpManager:
1. .1.3.6.1.2.1.25.3.2.1.5.1
Printer Operational status like Up, Down or Warning
2. .1.3.6.1.2.1.25.3.5.1.1.1
Printer Current status like idle, printing, or warmup
3. .1.3.6.1.2.1.25.3.5.1.2.1
lowPaper, noPaper, noToner, doorOpen, jammed, offline
4. .1.3.6.1.2.1.43.16.5.1.2.1.1
The content of a line in the logical display buffer of the operator's console of the printer like "Sleep mode on"
These OIDs are taken from the standard Printer-Mib which is available under /OpManager/Mibs. So, mostly it should respond for all the printers. If any particular printer model is not responding, we need to find the right OIDs and customize it in OpManager.
