It looks like HP stopped making drivers
for that printer at XP. I doubt you will find a 3rd party Windows 7 driver
for that particular printer.
You can try and install the driver in Compatibility Mode. Right click the driver package's .exe installation download/file and choose Properties > Compatibility Tab. Make your selections, then run the file using the "Run as Administrator" option.
Windows 7 may also have a generic printer driver for that printer that it will install automatically, but it may not allow all or some of the all-in-one features to work.
