Setting up a wireless printer entails either (a) using a software 'wizard' from the manufacturer or (b) setting it up manually. If the software wizard fails, then you're left with having to set up your wireless printer manually.
To manually set up your wireless printer, you'll need to (a) use WPS, where you push the WPS button on the printer and then (within 2 minutes) push the WPS button on your router or (b) use the tiny LCD screen (shown above) and laboriously find the place to enter your wireless password so that your wireless printer joins your wireless network.
Once your wireless printer is successfully added to your network, then Macs, iPhones, iPads, and Droid phones should all be able to find it without any trouble. On the other hand, PCs often have trouble finding network printers, even when other devices are able to print without a problem.
If your PC can't easily find your wireless printer, you can add it manually. The first part of this process is to find out the IP address of your wireless printer. This can be done by (a) working within the tiny LCD screen or (b) logging into your router's administration page and looking for your printer in the 'attached devices' section.
After figuring out the IP address of your wireless printer, adding a wireless printer manually on a PC entails these steps: (a) Click on the gear icon after clicking the start button, (b) choose devices, (b) choose printers and scanners, (d) choose add printer or scanner, (e) if it fails to find your printer, choose 'the printer that I want isn't listed', then 'add printer by TCP/IP address or hostname' and type in the IP address of your printer and click next.
If you have trouble setting up your wireless printer, the two hardest parts of this process would be working with the tiny, clunky LCD interface on your wireless printer or logging into your router to find out the IP address of your wireless printer.
