Retrieving Print Jobs like HP Web Jetadmin ( SNMP )

Hi,

i need to retrieve print jobs by users like HP Web Jetadmin does with specific printers (for excample: LJ P3005 or Color LJ 4730 MFP).

I think Jetadmin does it through SNMP.

I tried several MIB's from http://spp.austin.hp.com/spp/Public/Sdk/SdkPublicDownload.aspx (LaserJet and Digital Sender), as well as the HP-LASERJET-COMMON-MIB, but i cant see a common way to get the information.

For LJ P3005 i can get some informations like printjob by user, domain, etc. with a snmp walk through OID .1.3.6.1.4.1.11.2.3.9.4.2.1.1.6.5.23, but i miss information like printed page count.

is there any common MIB / OID to get those printjob informations from several printers?
