I've had my HP ENVY Photo 7800 series printer working fine for some time and then I got stupid.While looking for a BIOS update for my HP ENVY laptop I noticed there was a new firmware for my printer and went ahead and installed it. Since then I've been completely unable to print but I'm not sure 100% of it is the printer's fault.When I try to add the printer in gnome settings after removing everything I get very weird behavior.First is say "Unable to add printer" or something to that effect, once I click through that it says it needs additional drivers.When I click Ok it takes me to hplip in Gnome Software which is ALREADY INSTALLED.And then gnome-controler-center partially crashes and has to be closed but not forced to quit.I've since moved on to trying to add the printer directly through the CUPS web interface. It discoveres the printer via both ipps and dnsnd. Sometimes it autodetects the printer type and other times I have to manually select it.I've tried both driverless, hpcups, and hpijs without success, however, I think that's because the driver is not the problem.The message I always get when trying to print anything, regardless of connection method, is:First:"Processing page 1..."And then:"Unable to locate printer "HP9C7BEF8B3751.local"."Well it could certainly locate it to install the printer but somehow it can't find it afterwards?!?journalctl -u cups has been utterly useless.Avahi seems to be working as avahi-browse shows a bajillion entries for the printer.Ideas?
How long ago was this? Ie have you fully powercycled the PC and the Printer since this all happened?
Otherwise do we start with systemctl restart cups, etc...
Have you checked back for another firmware update.
Checked the status page on the printer itself. (EWS embedded web server)
