Accessing printers but not files

Hi,

Not strictly a security question but it does involve keeping the 
security of some of the information secure.

I am using broadband via a cable connection plugged into the router hub. 
The router also has wireless access and there are two Win XP wireless 
laptops using the service, totally legit.

I do not have a printer, but the laptops do. Is it possible and also how 
could I enable the use of the Win XP printers, from my cabled access to 
the router, without having to enable file sharing whilst keeping the 
data on the laptops secure?

Regards
Hylton
