It's not clear how your printer is set up. Is it attached to your router? If
so, turn on the printer, then in Ubuntu run Administration/Printing. Click on
"add," then select "network printer." Wait a few seconds and the printer should
appear. Just select it and proceed (forward? I forget the exact wording). I have
a Brother laser printer attached to my router, and I play around with a lot of
versions of Ubuntu or Mint. This always works for me.

If the printer is attached to the Windows computer, make sure that "file and
printer sharing" is turned on in Network Properties. Then right-click on the
printer in Control Panel and make sure the printer is shared; I think you have
to give it a name. Once those things are done, the Ubuntu setup should be as
described above.
