Linksys WPS 54G

I have the WRT54G Wireless Router
and the WPS54G Wireless Print Server

I have an IBM and a Mac Laptop (powerbook g4)

I am able to use the wireless router with both computers.
I am able to use the wireless print server with only the IBM.

I would like to be able to print wireless with the PowerBook G4 as well but am unable.

Could someone please advise?
