Your network should have been mosly setup already because of the router, if all your pc's are in the same workgroup, assuming you don't use AD @ home, on the host, just right click the printer share, choose all applicable options. Now on the other machines, just go through the My Network icon to the pc with the printer on it, now you should see the shared folders, printers, etc. If you double click the printer it shoud ask you if you want to add this printer and then hit yes, this should automap the printer for you, I know it does for me.
