    Hi Bruno,

    There are standard MIBs defined to do (most of) what you want.

    But most printers do _not_ implement the Job Monitoring MIB
    (RFC 2707), so you can't reliably monitor network printer jobs
    with SNMP (without using vendor private MIBs).

    Most printers _do_ implement Printer MIB (RFC 1759/3805).
    But most printers only support registration by a monitoring
    client for SNMP traps (toner low, etc.) using vendor private
    MIBs or local system consoles.

    If you're willing to poll a single object (prtAlertAllEvents)
    in newer printers that support Printer MIB v2 (RFC 3805), then
    you can check the prtAlertTable for the new alerts efficiently.
    Many (but not most) network printers now implement RFC 3805.

    Dear folks,

    I have some questions about MIB and SNMP, and I couldn't find the
    information I wanted anywhere, and I was hoping you could help me.

    I wanted to develop an application that captured print jobs to network
    printers, monitor those jobs on printers (if they were printed, how much was
    printed, color, mode, etc), and monitor printers.

    - Could I monitor those jobs throughout my network using MIBs and SNMP?
    (Catching who sent the print, print size, color)
    - Do printers using MIB send alerts to an application without the
    application requesting it? (I don't want the application sending requests to
    the printer every 10 minutes, I want the printer to send alerts like toner
    load, paper load, lid open)

    Thanks for your attention.
