Windows 8 is essentially Windows 7 with the colored tile interface laid on top (plus a few other changes) so I would have thought a printer would still work.
Have a look on the company web site (who make the printer) and look under "support" and search for the printer and see if they mention Windows 8, or if they have brought out a new driver or software package for Windows 8.
They may even have a section on what printers will work with Windows 8 so hunt round the web site.
A search in the internet for "Windows 8" and the printer name may also find some other "hits" as you may not be the first person to try to get it to work.
