HP Laserjet 1300n – SNMP – Help

If any of you IT guys could help me with this, that would be great, yeah. I’ve got 6 of these badboys with JetDirect 200m hooked up to them on the network. What I want todo is monitor the toner levels with SNMP. I’ve been able to get the number of pages and the total number of pages, memory and such, but nothing really usefull. I’ve done so many searches on MIBs and OID trying to find the information but no luck. Heck it might not even be possible. I guess I’m gonna break down and get a copy of WebJet Admin (or whatever there software is called) and try that. But what I wanted todo is use it on my linux server to send me an email when the toner is low. Thanks for anybody that can help.
