I realised that you were asking about a different printer to the one in the possible solution. (If the 'missing' HPQVWR08.EXEfile isn't on the installation CD that would possibly be a clue that the 'hints' that I posted don't apply to you.
)
The HP links were found simply by typing the HPQVWR08.EXE file name into their technical support web site without specifying a printer model.
I do not know if HP release this file for different printers with different contents to the file or if it is intended to be the same contents for every printer that needs the file.
In an earlier problem (see Wierd Printer Problem thread). The problem related to an HP5550 that printed out blank pages. I had the same blank page problem when I put an HP6122 printer on a XP (SP2) machine the week before. I realise that the solution, a Windows setting, is unrelated to your 'driver' problem but I wonder if HP are using the same utility files (with the same installation problems) for different printers of the same generation? Much better brains than the poor one I have would be needed to answer that.
Good luck.
