P1102W HPLaserJetService.exe Unhandled Exception

[Kevinder]

I just installed the latest software for the P P1102W laserjet. Upon reboot, and every reboot, I get an error that says:

An unhandled exception ('System.NullReferenceException') occurred in HPLaserJetService.exe [######]. 

The ### varies. I've seen 10440, 8172 and 10112 and others.

HP LaserJet Professional P1102W

Firmware Datecode 10230703

Driver version 20101117

I also have a HP OfficeJet 4650 installed:

HP OfficeJet 4650 Series

Driver Type 3 user mode

version 17.590.4938

Any ideas?
