Hi guys, I'm exhausted on this one. Same printer has been connected and working fine via wifi for months, this morning it's not printing, nothing changed. When I go to printers and scanners I can see the printer model but next to it it just says "driver unavailable". I've uninstalled all drivers and software, removed printer and installed the latest driver. It finds the printer absolutely fine when it searches for printer to install on network but after taking an age continuing with the install process, it says unable to install printer on network. When I run the HPSmart app I can see the printer is clearly connected to the network but where it says printer installed it says no. If I then go back and look at my printers and faxes, it shows the printer as "driver unavailable" again. When I click on manage, it seems to be only picking it up as a scanner imaging device and no way of setting as default printer as it shows it as a scanner. I've spent 5 hours today trying to get it working but still no joy. Any ideas? I've exhausted Google searches and spent ages on hp site but still no good.
