Printer going offline after printing

[butorides]

Trying to configure wireless. My printer goes offline within minutes of printing. I'm using several Mac OSX devices (10.13 and 11.01). If I unplug the printer (Envy Photo 7855) and allow it to restart, it will print for a few minutes (<5). Then it goes offline and the computers endlessly look for it, or it registers as offline.

I've:

-removed and re-added the printer from the Printers and Scanners control panel in system preferences

-reset the printing system

- Downloaded and run the HP uninstaller and (per the "Fix HP Printer issue in macOS) info

-Assigned a static IP address (per the "My MFP281fdw printer constantly goes offline." thread) (Note- the OSX 10.13 device can't even open the printer's embedded page because 1) bad security certificates and 2) constantly times out. Was able to reset manually for the OSX 11.01 machine, but this did not solve the problem.)

I actually just purchased this Envy 78655 because my 7800 stopped working with this same problem. Seems like it wasn't bad hardware- maybe bad software. I can certainly echo the frustration other users have noted with this constantly dropping offline issue. 

Anyone find a solution?

I guess I'm learning a lot about HP's commitment to support?

I reviewed your post and I understand that you are facing issues printing wirelessly.

Don’t worry, I assure you I will try my best to get this sorted.

I'd like to know the following to isolate the issue further-

1.) Are the printer and Mac connected to the same network?

2.) Is your router dual-band enabled i.e., both 2.4GHz and 5GHz? If yes, make sure the dual-band has different SSIDs for 2.4G and 5G networks.

3.) What is the distance between the router and the printer?

4.) Is there an antivirus software installed on your Mac?

5.) 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.

The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold option-click the WiFi icon and then use shift-command-5 to take the screenshot. Press the space bar when the icon turns into a camera. Share the ping test results and the screenshot with us.

Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.  Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems. 

Look forward to hearing from you and have a great day!

Take care.

Cheers!
