Turn the mirror image option to on. If it does the same turn it off than uninstlall and reinstall the complete software.

• Go to the Printers Menu and select Add Printer
  
• Add a Local Printer
• Create a new port - type: local port
• For the port name, enter the share of your printer on the remote computer.  For example, if your computer name is superDesktop and the printer share name is megaPrinter, you'd type in \\superDesktop\megaPrinter.
• Finish the wizard and you're done, printing normally!

SJAK00's solution is exactly right but here is more detail if you're like me and need step-by-step detail on how to find these tabs: Go to Control Panel and Open Printers and Faxes.
For the first setting change: Right click the printer you want to set the default printing preferences on. Click on Printing Preferences, then on the Advanced Tab the Printer Preferences will list Mirror Image, which probably says: "On"--click on this and choose "Off", then save the setting by pressing OK.
For the second setting change: Open the printer settings by double clicking on the computer in question. The printer screen (the one that shows the jobs in process) will come up and at the top click on Printer. Go again to Printing Preferences, and again switch the Mirror Image desigantion from "On" to "Off" and save it.
This worked for me. Jan

You'll need to go to the manufacturer's site and find Vista drivers for your HP. Going from Win 98 to Vista is a major jump. I had to convert from XP to Vista and I still had to go get Vista drivers.

Also, make sure you get 32 or 64 bit drivers for the system.
