I cannot get my HP Officejet Pro 8620 to print.

Good day! I'm Raniel. I understand your frustration regarding this issue and I'll do my best to help.

Just to clarify, aside from the edge chromium, did you also make any changes to your machine before encountering this issue (like installing third party apps, recent updates, etc..)?

Kindly run the printer troubleshooter first: Go to Start > Settings > Update and Security > Troubleshoot > Printer > select Run Troubleshooter.

Kindly close all applications that are running on the background and restart the print spooler:

1. On you search bar, type "Command Prompt" and select "Run as administrator"
2. On the command prompt window, type net stop spooler. If that doesn't stop the print spooler service, type "services.msc" > look for "Print Spooler" > right-click on it and select "Stop"
3. Open file explorer and go to the location C:\Windows\System32\spool\Printers and delete all the files on that folder
4. Go back to the command prompt window and type net start spooler and try to print again

If that didn't work, another option is to reinstall the printer driver using this method:

1. Uninstall all printer software from your control panel
2. Press Windows+R on your keyboard and type the command printui /s /t2 and press Enter
3. Under the Drivers tab, select the printer driver and remove it
4. Go to the Ports tab and delete all the printer manufacturer's printer ports
5. Reboot your machine, then reinstall by getting the latest printer software and drivers from the printer manufacturer's product support website

I hope this helps. Good luck!
