Can't print using HP 845c printer after SP1 update

[boots56073]

After installing SP1 I can no longer print using my HP 845c printer that was
working fine before the update.

I have so far (numourous times) uninstalled the printer driver and usb
printer support, unpluged the printer, restarted the computer and pluged the
printer back it. Vista sees the printer and reinstalls usb printer support,
the printer driver and a unkown device. According to Vista everything is
fine, I can't find a unkown device even after showing hidden devices in
Device Manager.

Next I set the printer as default and print a test page, the page is put in
queue and deleted before it's sent to the printer.

Let me know any info you need.

Thank you

Fixed. Vista installs two 845c printer drivers. A 845c and a 845c series. By
default the 845c series is selected. Changed it to the plain 845c and now all
is well.
