I am unable to AirPrint after changing WIFI provider

I changed my internet provider and router. Thinking it would be brilliant, I changed the new router to have the same Wifi Name and Password. It worked with all my devices but not my printer (brother laserprinter). After re-finding network with printer… Now my phone (XR) and pad (10th gen) will not print. The printer name appears in airprint, but i cant assign it to print (I suspect its following some previous key route). Is there a solution besides changing my wifi name, so i do not have to alter every device on it?
