We have one USB printer that we want to share between two computer. We are tired of going under the desk to switch the USB back and forth from each computer. Do they make hardware that will allow you to share a printer with two computers? If so what is it called?

Its called a router----$20.00 on ebay

Don't Routers share internet connections. Please be more specific, I am new to this. Please give link to what I need. I have a router to share internet, but I want hardware that will allow me to put a USB cable from each computer into this little hub, then from the hub to the printer.

do you currently have a network setup between the two PC's for internet connection sharing? If so, all you need to do is setup a defined share. If not, there are several options (one of which is to do what I just asked) or you can use a crossover cable between the two NICS and share the printer. List what you have setup topology and hardware wise and I'll tell you the quickest/easiest way to pull it off

Acutally, I have a router, be we are just sharing our internet connection through a hub because our internet modem already has a F'wall in it So, our modem is acting as a firewall, and we have our ethernet cables hooked up to a hub.

All you need is the hub. You just need to make sure that the computers are on the same workgroup. (If you right click my computer, go to properties, select the computer name tab, and choose "Change" you can change the workgroup that the computer is on if necessary) Then once you have both computers on the same workgroup, go to the computer where the printer is physically connected. if you go to the control panel, and then go to printers all you need to do is right click the printer, go to properties, select the sharing tab (assuming you are running windows xp) then if you get there and see an option that says "if you understand the security risks and want to share the printer without running the wizard" click it. On the popup window select the option to just enable printer sharing. Now on the second computer, go to the control panel, double click the printers icon. Select add a printer, then select the option for a network printer, on the next screen select browse for printer and next. then on the next screen you should be able to navigate to the printer. Select it and follow the prompts. Hope that all helps. If you need any clarification just let me know.

Also for clarification, I assume your router has a built in switch. I say switch and not hub because hubs are older technologies that aren't really made anymore due to the inexpensivness of switches. For time sake lets just say switches are much smarter and better than hubs. If you have a hub you might think of looking into a switch. Again they are cheap. (And yes, routers are different than hubs and switches).
