Printer OID does not work on every printer

Hello I was asked to write a program to ask every printer in the network for there, name, location, and CMYK toners(how much percentage are left). I serched for the OID'a and everything was working. Now that i have the program that gets the data from all printers at some printers i does not work and the program shuts itself down. Why is that ?

Thanks in advance. Yours sincerely Scarlet

The problem is that there is no common MIB to monitor all printers. So it is very vendor specific. There are several most commonly used MIBs to monitor printer devices:

• PARALLEL-MIB - MIB module for Parallel-printer-like hardware devices.
• PRINTER-MIB - MIB module for management of printers.
• IANA-PRINTER-MIB - IANA basic SNMP definitions for printer devices.
• HP-LASERJET-COMMON-MIB - Hewlett-Packard definitions for LaserJet series devices.
