I've tried doing exactly the series you just laid out, yet i'm getting no fruit for my efforts. here's what i am coming across:
Installed using DOT4 port
Select Vista32 drivers
fresh from HP
Installation Completes and Device shows up in CPanel with green check mark
Open notepad and print text --> icon turns to yellow hazard and doc stays in the spooler with no status.
So... Rclick printer and 'troubleshoot' only to get "Troubleshooter cannot identify the problem".
as soon as I cancel the document the icon status changes back to a green check mark.
