[rpgman]

This is what I did to fix the issue...

I did try all the other suggestions that have been posted but it would find the printer in one part of the instructions and in other parts it wouldn't.

I spent maybe 5 hours trying to resolve this issue and finally this worked...just sharing for others:

I did up to the part before the Install latest drivers and it worked.

Question:- I have a brand new HP Officejet Pro 8710 printer which suddenly went offline. My printer is connected to the wireless network but still, it says printer offline. When I tried to print from my other computer it prints fine but not from my laptop. I can print from my iPad and iPhone. We ran HP Scan and Doctor but nothing works. I don’t know what’s going wrong with this HP 8710 printer. Can anybody tell me why my HP Officejet pro 8710 is offline and how to fix this printer offline error?
