If your printer has a USB port, you can plug in a wireless print server, a small box into which you can connect your printer. The advantage of investing in a print server is that you don’t have to connect the printer to a PC, which means you can use your laptop and print anywhere in your home. We found plenty of print servers in the $50 range on Newegg.com, although many of the models cost closer to $75 or $100). Before you buy, make sure the print server is compatible with your printer (the printer’s written materials are less likely to specify compatibility with print servers).
During the setup, you will have to plug the printer into the printer server, and connect that to the router using an Ethernet cable. Meanwhile, you’ll have to install software on your computer and configure the connection, as you would when setting up a router.
