My printer which was connected and printing wirelessly is now not doing so

[printgran]

My printer was working fine with wireless but it has stopped working without an ethernet cable.  It seems to happen whenever we have an internet outage or a very brief power cut or also when I have installed updates on my apple

@printgran, Welcome to HP Support Community!

Follow the steps below-

1. Turn the printer off, and then wait 10 seconds.
2. Disconnect the printer power cord from the printer.
3. Turn off the computer or the device you are trying to print from.
4. Connect the printer power cord to the printer, and then turn on the printer.
5. Disconnect the power cord from your wireless router, and then wait 10 seconds.
6. Reconnect the power cord to the router. Wait until Internet service is restored. Internet service is interrupted while the router is off.
7. Turn on the computer.

Try printing.

If the issue persists, I would like to know the following:

• Are the printer and PC connected to the same network?
• How is the printer connected, via ethernet cable or wireless?
• Is your router dual-band enabled i.e., both 2.4GHz and 5GHz?
• What is the distance between the router and the printer?
• Is there any antivirus software installed on your computer?
• Could you perform a ping test using the Mac Network Utility and let me know the results?

Use the printer IP address to perform a ping test, the printer IP can be located by selecting the wireless icon on the printer display.
