Here are the below OIDs we use to get the status of the printer which are hard coded in OpManager:
Printer Operational status like Up, Down or Warning
Printer Current status like idle, printing, or warmup
lowPaper, noPaper, noToner, doorOpen, jammed, offline
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.
