I have two hp wireless printers which worked fine until some days ago.
Now, my HP Officejet Pro 6830 has a strange issue. Even if it appears as installed both in the (new) windows 10 Printers & scanners dialogue, as well as in Control Panel > Devices and Printers, when I try to print, the print queue remains empty. Moreover, MS Word 2010 (after having selected the right printer and clicked on print) opens a pop-up telling me: "Word cannot print. There is no printer installed".
In CP > Devices and printers, if I right-click on the printer and on Properties, Win10 tells me: "The HP Officejet Pro printer driver is not installed on this computer... do you want to install now?". If I click 'yes', the driver seems to install correctly, and the wizard exits with success. However, if I try to print a test page, the system tells me: "test page failed to print" and suggests the use of the in-built troublesshooter. That one is not able to find any issue.
The HP Printer Assistant is working correctly, and I can connect via WIFI to the printer homepage.
I have tried uninstalling all HP software & drivers, but if I do that, on reinstall the installer is unable to connect to the printer and to register the printer with the OS, even if the software correctly detects the printer on the network.
