You can try the KXP1180 Driver... This is a fairly common driver that will work with nearly all 9 pin Panasonic Dot Matrix printers and has had both XP and vista versions setup.
Go to control panel
Printers
Add Printer
Then auto sense your printer, if nothing comes up try selecting the KXP1180 then try and print a test page...
You will still have to manual set your page size under Excel but with a little experimentation you should be able to get this right...
