Printer Setup, Software & Drivers

I have an Officejet 3834, and I work with a HP laptop with Windows 10 64 bit, version 21H1, build 19042.1288.

I've installed all the recommended drivers and softwares (Officejet 3830 series, HP Smart).

The printer appears to be online and ready. It does scan, but it doesn't print.

When I try to print something, nothing happens and the document never appears, not even for an instant, in the print queue. If I run the HP Print and Scan Doctor, it doesn't print the first test page, but it does print the internal test page, and then it states that "there is a problem with the software that cannot be solved with this tool. Remove the software, and download and install the most recent version of the software". I've done all these, but the problem persists.

The same printer works fine on a different pc (older, with Windows 10) on which it had been previously installed. On my present and recent laptop, I initially had Windows 11 but then I switched to Windows 10, which I prefer. I had the 20H2 version, and at first the printer worked, I was able to scan AND print. Then, a few days later, it stopped printing. I then upgraded to the Windows 10 version 21H1, but it made no difference.

Besides removing and reinstalling printer (both wireless and USB), softwares and drivers several timeso and keeping Windows updated, I've also tried disabling the Defender firewall, and I made sure that all the ports listed here https://support.hp.com/it-it/product/hp-officejet-3830-all-in-one-printer-series/7172321/model/77239... were enabled. It made no difference.

I also tried the steps suggested here https://h30434.www3.hp.com/t5/Printer-Setup-Software-Drivers/HP3830-not-printing-in-windows-10/td-p/... (except for creating a new administrator account), but it didn't work.

Any suggestion on what I should do?
