I'm sorry about the issue. What's the model of your HP printer?
Does it show not connected to the internet on the computer's monitor / screen or on the printer's screen?
Are you currently able to make a copy from the printer's glass (not printing from the computer)?
Please reply at the box below. Thank you,
What's the model of your HP printer (not your Macbook computer)?
Thank you. Is the printer wireless? Or is the printer connected to the computer with a USB printer cable?
- If the printer is wireless, on the printer's screen, when you press the Wireless / signal icon, then go to the Wireless menu / wireless settings -> Wireless Setup Wizard, are you able to connect it to your wireless / wi-fi network name? Is there any error or message?
Also, what did HP try, if any? Was there any error or message?
- If you put a document or photo faced down on the printer's glass, then press the Copy option / button, does it copy fine?
I see that you requested a new answer from another expert -- Have you disconnected the printer from your router and reconnected it through the printer screen?
