Hey There, I am Sofia Carter. Most wireless printers use WPS technology to connect the printer wirelessly to the network and computer. WPS setup is a secure way to connect your printer to your various devices including computers and mobile phones. To establish the printer connection on your PC, you need to enter an eight-digit WPS Pin. You can find this Pin on both your devices, computer, or printer. Every time you try to connect your printer to any device, a new Pin is generated and shown on the printer screen. The default WPS Pin can be found on the back of the wireless router too.
