Re: DRIVER NEEDED: Hewlett Packard (HP) Q5403A (Windows 7) [USB]
Panasonic never released drivers for Windows 8 (and has no plans to do so). You're only chance at getting this printer to work in Windows 8 is to hope Microsoft included a basic driver with built-in drivers. If the KXP1121 is not listed under "Add New Printer", then choose one that is close to that model. And you can also try basic drivers like Epson FX or IBM Proprinter Graphics to see if they will work.
