HP LaserJet 4100N-print queue reverts to pause
I've been trying relentlessly to get my iMac (early 2008 model) to print on an HP LaserJet 4100N. I've been able to establish the connection (via ethernet) using the IP address on the printer and configuring as Protocol LPD, HP LaserJet 4100 Series v.3010.107. All looks good, including valid connection, etc. However, when I try to print the printer queue goes into action, shows that it's "printing-copying print data-printing", but as soon as it gets to the next step "connected to printer" the job suddenly drops and reverts to pause mode. According to the information provided under printer "Options and Supplies", I have driver version 19.5. HP says that OS 10.6 comes with the necessary driver (where I started before upgrading to Mountain Lion), and that an update for Mountain Lion can be found under Apple's Software Update. But no such update is found.
My older PowerBook G4 with OS 10.6 works fine, so I'm assume it's an issue with the software/driver that's supporting Mountain Lion.
Any suggestions?
