HP printers no longer connecting to my PC

[sidmouth]

Hi

I have a 7510 and on a separate network a 8620, all was working fine for about a year, then Monday I cannot print of any printer even if I change networks.

It says printer not connected, if I un installed the printer and try and find it again it say the driver is unavailable, I have un installed the drivers, re loaded them, tried the HP Doctor, nothing works, even tried resetting all printers, modems laptops.

I brought in my old laptop and it printed fine, this Laptop in question did just do a new software upgrade,

Any info would be useful

Hi,
Please follow the steps below to resolve such an error:

**Be aware that if you have other printers installed on your PC, those will need to be reinstalled too once completing these steps.

1. Uninstall the HP Software from your PC.
2. Backup your registry prior making any registry changes:

3. Update your registry using the Reg file below (that will change some printer related policies for your PC):
     https://www.dropbox.com/s/avbv56zdgwv7600/kernel.reg?dl=1
4. Right click the Start menu and select Run.
     Type Services.msc and press OK.
     Locate and stop the Print Spooler service
5. Browse to c:\Windows\System32\spool\drivers.
     Rename W32X86 to W32x86.old
     Rename x64 to x64.old
     Note: if any of these folders fail to rename reboot your PC and then Continue following the steps starting from Step 4...
6. Restart your computer.
7. Reinstall the HP Software and check for any difference

Please let me know the results,
