I am trying to help and friend set up their new PC (with Windows vista). They have a HP 5550 colour printer. According to HP support site it is compatible with vista. We've installed the driver for the printer via the Add Printer wizard which has installed the driver, but when we try and connect the printer via a USB cable it immediately crashes the PC and shuts it down, with no error messages.
Can anyone think of what could be causing this please? Its puzzling me. Cheers
