Thanks for posting your question on Justanswer.com, a global paid independent support site.My Name is ***** ***** I will be assisting you today. Do you replaced the router, before the printing problem started ?
OK, please power off the router and printer for 1 min. then turn them one, after that wait for 5 mins and try to print from PC.
Can you tell me, what is exactly happening, when you try to print ?
