HP Color LaserJet 2840 Incompatible with MAC OS 10.6 Snow Leopard

Question

The printer defaults to "pause" when attempting to print. Clicking "resume printing" does not unpause the printer. I spent one hour with Apple tech support yesterday with no resolution.
I removed the printer from System Prefs, then reinstalled, but that did not resolve the issue.
HP tech support advised designating "Generic PostScript Printer" in the Print Using box when then adding the printer, but it still defaults to "Pause" when attempting to print anything.
No problems with the Canon Pixma.
Advice would be much appreciated.

Upon upgrading to Snow Leopard, I could print but could not scan. Deleted all existing printers that pointed to my CLJ 2840. Uninstalling and then reinstalling the 10.5 drivers resulted in a dialog box that stated there was a problem installing /System/Library/Extensions/hpcolor_lj_2800series.kext
The printer was not automatically found, and could not be manually added via HP Setup Utility. I decided to fix the problem with the kernel extension (kext).
I opened a terminal and ran the command
sudo kextutil /System/Library/Extensions/hpcolor_lj_2800series.kext
which informed me that there were problems with the permissions on that kernel extension. I then ran the commands
cd /System/Library/Extensions
sudo chown -R root:wheel hpcolor_lj_2800series.kext
sudo chmod -R g-w,a-w hpcolor_lj_2800series.kext
and then rebooted and that seemed to do the trick.
The only thing that doesn't work now is the Fax fuctionality. the URL for the fax is set to "file:///dev/null", which doesn't seem productive at all. I'll post when I discover anything there.
