Hi All, I am trying to use the check_snmp_printer plugin to monitor the toner status and the other parameters related to our HP Color Laserjet 2600n network printer. Initially I struggled to make it work because I was getting blank output for various checks using the check_snmp_printer plugin. I found that the snmp agent on the printer was not supporting the OIDs used in the plugin script. So, I upgraded the firmware of the printer and found that many of the OIDs (though not all of them) used in the plugin are now supported by the printer. I am able to get the status of the black and the color toners using the "check_snmp_printer <printer_ip> <community> CONSUM BLACK" (and similar) commands. But I observe that the output of these toner check commands is not consistent with the toner status I get by using the "web-based device status" of the printer. For eg. the web access of the printer web page gives the toner status as follows: Black: 83%, Cyan: 42%, Yellow: 42%, Magenta: 42%. As against this, the check_snmp_printer gives the status as follows: Black: 84%, Cyan: 82%, Magenta: 87%, Yellow: 85%. Would like to know whether anybody here has had a similar observation and the workaround if any for this. Thanks in advance. Yogesh
