Just a quick tip on the 79 Service error many seem to experience at times. While I've been through several posts that offered up various suggestions, for the printer above nothing I found was working. Finally got into the control panel by disconnecting all networking and started poking around. No recent firmware updates, network settings seemed fine. One thing I noticed that I still had Google Cloud Print enabled as this printer was hooked into Google Cloud Print for a while. As GCP was shutdown at the end of last year, and since it seemed my issue started on April 1 (April fools Google?), I decided to just shut down GCP on my printer. And.....it actually seems to have resolved the issue. Making a guess that Google still had services up that was allowing the printer to talk to the GCP infrastructure, and likely those services are now down as well, causing the 79 Service Error.
