|Are you using XP (or 2000) or a Server operating system or similar to XP on the subject computer ? All I know about Server operating systems similar to XP is most things in it are the same as in XP.|
You DO NOT need to Add a Printer there (in 2000 or above), network or directly connected, unless the printer is NOT Plug n Play. E.g. parallel connected printers are not Plug n Play.
When you install the software for a directly connected printer properly (NOT just the drivers), the printer model appears automatically in Printers and Faxes, BUT when you first install the software, it does not appear there immediately - it WILL eventually.The printer will work fine after the software has been installed for it properly (you MAY have to Restart the computer once) even BEFORE the model appears in Printers and Faxes.
(If you DO need to use Add a printer because the printer is not Plug n Play, you only need to do that on the computer the printer is directly connected to.)
When the software for the printer has been installed properly on another computer on your local network it has been connected directly to, if File and Printer Sharing or similar has been enabled on all the computers in the network, the printer model will appear automatically on all the other computers in Printers and Faxes as a network printer on the computers it is not directly connected to, BUT, again, it does not appear there immediately, but it WILL eventually - the other computers need time to install drivers that are conveyed over the network connections. (You DO NOT need to install any software for the printer yourself on the other computers the printer is not directly connected to.) You MAY need to Restart all the computers in the network at least once in order for the network printer model to appear in Printers and Faxes initially.
(A network printer model that is NOT Plug n Play will appear there too.)
Similar applies to printers that are network connected directly. Similarly, you probably must install the software properly, NOT just the drivers, on one computer in the network.
