Manually uninstall HP printer drivers

[mesapegasus]

Windows 7 Professional SP1
HP Color LaserJet 2600n

I built a new system and am trying to have it print on my networked HP Color LaserJet 2600n. I used the original install disk and it failed. Now I cannot uninstall from Control Panel ("setup encountered an abnormal program execution.") This is preventing me from installing new drivers downloaded from HP.

Is the an HP Force Uninstall Utility? If not, what files and registry keys do I need to nuke?

Answering my own question in case it helps someone...

Run "printui /t2 /s"
Tab Ports
Delete a bunch of jammed up copies of ports on the IP address of my printer
Run "hp_CLJ_2600n_Full_Solution-v20110217-50132926-RC5-Signed.exe" obtained from HP support website.
Success
