Officejet 8012 - Not printing.

[Giovanni_Vinci]

the printer was running smoothly for many years.

But i Cannot print from my desktop.

After experiencing this problem i carried out the following:
I removed drivers and uninstalled all HP SW.
I downloaded and installed  the newest SW and Drivers and Firmware as downloaded from HP Web, having Firewall disabled.
The SW HP smart reports that the printer is Ready, Installed and connection active.
I can see it properly connected to Router.l
The HP future ScantoPC is working perfectly.
I tried to monitor the print queue while testing with print test page, I saw the information for 1 second in the queue than it disappeared as the process was completed, but no print output from the NICE Printer.
Up to now I can print from my smartphone and from my laptop, but absolutely not printing from either with Firewall enabled and/or disabled.

i checked the driver on laptop and they are the same installed on the desktop. i checked device manager and ensured that  have the print queue HP device officjet 8010 series, the port WSD and the printer are properly installed. i disabled the router, I switched off cable from printer and reconnected.... NOTHING TO DO!

Suppose a problem between HP SW and Windows.... but where?
Many thanks to anyone able to help me.

i Called by phone HP Support Service, 
The problem was with latest Windows update carried out on 16 Sept 2021. 
With their remote assistance we put printer with static IP Address, then installed a new driver OJ_SF_K8600_140_408-4.
Now I have two drivers (printers), the original one 8012, necessary to use the scan services, and the new one 8600 for printing services.

Fine,

Many thanks to HP Support  Services
