I just recently bought a new printer that can work with wireless.
I have 2 desktop computers:
One my wireless router is hooked up to;
And one that is connected to my router via Ethernet cable.
Now the desktop with the router connected to it can print wirelessly, while the other desktop can't even detect the printer.
How can I get my second desktop to be able to detect the printer? Thank you!
Your router has a wireless encryption key (essentially a code number, sometimes erroneously called a password) that prevents unauthorised access to your wireless connection.
In your printer's setup menu on the printer itself, you have to go into "Wireless Settings", look for the name of your router (SSID), and enter that wireless key so that the printer can connect wirelessly to the router.
You do need to install the drivers for the printer on both computers and then after installing the printer on the network as a network printer as Phil22 described you can add the printer to the second computer in printers and other devices.
