MacBook won’t find my HP Officejet 250 mobile
I have been printing from my MacBook for about a year. We recently moved to a new site and changed the network. Both the MacBook and printer are connected to the same network but neither my MacBook nor my iPhone will find the printer. I have restarted all of them numerous times and even went back to factory settings on the printer. Additionally, all Apple software is up to date. I am stuck on this one. Can anyone help please?
MacBook Pro 17″, macOS 10.12
