This issue has started cropping up recently in multiple locations with multiple printers in various environments. We have a an HP MFP 1536dnf printer in a couple of locations. Each location has a simple local network and a couple of computers. Within the last 2 weeks Error 79 has started appearing on the printers. Doing a reset has not been successful and we are using the latest drivers from the HP website. We have also replaced and swapped the printers to no avail.
Interestingly, if I shut off one of the computers, delete the print queue in the computer that is still on the error goes away and printing works.
Once I turn the other computer on the problem ensues. Reinstalling the driver on the offending computer causes the problem to stop for a few days and the same problem happens again requiring a driver reinstall. This has happened in two different locations that are not connected to each other around the same time period. This setup has been working for over a year before this.
My guess is possibly some kind of automatic update happening, possibly with windows update that is causing this problem? Does anyone have any insight into this?
