sharing printers and files via a wireless router

[Steve]

I just installed a Linksys 4port router. I configured it
to share an internet connection with a client computer.
The client computer has a compatible pci card installed. I
have two computers in my home network, both are running
Windows XP home edition. I was successfull in sharing the
internet, but not a printer. What can I do to complete
this task?

Thanks
Steve
