Hey There, I am Sofia Carter. Wondering WPS Pin On Printer and what’s it used for? It is a unique 8 digit code generated by your wireless printer to establish a wireless connection between your device and the router. You can use this WPS Pin to connect your printer with the wireless network and then use it wirelessly to print from various devices. The use of a WPS pin to connect devices prevents unknown users from getting access to your device unless they have the code as well. If you are looking for this PIN to connect your printer wirelessly to the computer then you should look nowhere else but at your printer control panel. If your printer doesn’t have a touch control panel, then use the WPS button instead.
