if you have more than one pc and they are hooked up on a network through a router , you might want to get a router with a print server built in or a print server instead of an ab switch . this way there is nothing to mess with and all your pc's can print to the one printer . like this one
or you can just set-up the machine the printer is on to share it over the network....puts load on the machine i guess but in home enviroment thats not noramlly a problem
