Oh... Networking is your answer.
What type of computers you have?
Operation system I mean.
I assume the printer is hooked up to a desktop?

Look for my answer to find out how to first set up your network.
Next, on the computer that you have your printer on, you're going to have to make it "sharable."
Oh cool, that is actually a word!
Lesseee...
(Not a word)
Windows XP:
Control Panel
Make sure you are in "classic view" (look at the left of the Control Panel window)
Go to "Printers and Faxers" (mind the spelling)
Now, on the printer you want to share, right click and click "sharing"
Obviously, you want to share the printer, so click "share this printer" (give it a fancy name if you like)
There you go, it's set to share.
Vista:
Control Panel
(Classic view!!!)
Printers
Right-click the printer you want to share and click "sharing"
Share the printer (giving it a fancy name if you like).
There you go!
On your other computer you have to add the printer...
Just go to the "printers/faxers" page again and click "add" and then click something to the extent of "from a local network" and find your printer to add it.
That's only if you have a Windows based computer...
Good luck!
