If you own a wireless router, and if your printer offer wired (not wireless) ethernet support, newly connect the printer to the router. (You'll enjoy to do some configuring of the router to trade name it available.) If your printer does not submit ethernet, afterwards you have need of a printer server. Linksys make one as do the other router manufacturer. Search for PSUS4 at

You would have need of a wireless router and a wireless printer. If you already enjoy a printer and don't want to buy a latest one, afterwards the printer would hold to be hooked up to one of the computers and you would own to set up a web between the two computers and "share" the printer over the framework. If you afford some more info nearly your set-up it will be easier to afford you more specific information.
