I need what I will need to make my printer into a network printer, enabling to print from 3 different computer?

Best Buy has a printer router thing you can go get in their computers section. You plug it into the USB port of your printer and it makes your printer wireless. There's other variations to this too. Go to Best Buy and talk to a computer specialist and they will help you out.

That is a lot of work. One of your computers will have to remain on all the time. You connect your printer to one of the computers, and you send the print tasks to the printer through the computer connected to it. It is a lot of work, so you should try searching for specific instructions on google or pay someone to do it for you. On the other hand, you can just buy a network printer. Easier alternative: email yourself the file to be printed, go to the computer connected to the printer, download and print!

they all need to be running the same operating system. then you need to setup a network on the computer connected to the printer. once you do that, you have to set the network options on the other 2. if you need more assistance, google it or something. there are tons of sites that will give you step by step guides. it's pretty easy to do. one thing to add. the computer connected to the printer will have to remain turned on if you are to print anything from one of the other computers. if the main cpu is turned off, then the print command won't make it to the printer.

You need an adapter that will allow you to plug the USB cord into the adapter then plug an Ethernet cable into your router.. I believe there called print servers.

Printer Share Switch or a Printer Hub. Both do the same thing. Hub is more expensive.
