[quote name='dd_mcdoodle']What I did in my home was I had one computer physically connected to the printer through the printer cable, and made the printer a shared printer on the network (go to printers in control panel, right click the printer, select "Share," and configure the settings). The only drawback is that the computer that is connected to the printer must be on for you to print from the other computer.

Exactly my setup. Keeping on isn't a problem, they're usually on 24x7 anyway, and if not, they boot up in 30 seconds. Especially since you already have a router. Make sure both pc's are in the same 'workgroup', and you should have no problems. Added benefit: it's usually a lot quicker and easier to share folders and just transfer files across the network than emailing them. If you have a router, that's got some built-in safety, but you should probably also password protect the 'share' access.
