Hello,

In order to palliate this incident, please follow the following procedure:
1. Uninstall printing software:

  1. Unplug the USB cable at the back of the printer, if necessary.
  2. On the keyboard, simultaneously tap the Windows flag and the R key. The Run window opens.
  3. Type appwiz.cpl, then OK. The Programs and Features window opens.
  4. Click the right mouse button on HP ENVY 4520 series Basic Software, then Uninstall and Yes.
  5. Follow the instructions on the screen to complete the uninstall of the printer.
  6. Restart the computer.

2. Launch the registry editor:

  1. On the keyboard, simultaneously tap the Windows flag and the R key. The Run window opens.
  2. Type regedit, then OK. The registry editor opens.
  3. Develop HKEY_LOCAL_MACHINE, then SOFTWARE, click with the right mouse button on Hewlett-Packard and Delete. (If the PC is HP-branded, develop Hewlett-Packard and remove Digital Imaging)

3. Delete the HP ENVY 4520 series folder in the way:

  • C: \Program Files\HP
  • C:\Program Files (x86)\HP

4. Rename folder 3 in 3_old in the path below (a restart may be required):

  • C:\Windows\System32\spool\drivers\x64.
  • C:\Windows\System32\spool\drivers\W32X86.

NOTE: If the file refuses this action do as follows:

  • On the keyboard, tap the Windows and R keys simultaneously. The Run window opens.
  • Type net stop spooler, then press OK.
  • Rename the file.
  • Type net start spooler, then tap OK.

5. Launch a new installation of the printer with the HP ENVY 4520 series Full Software and Drivers.

 

I remain at your disposal in case of need.

Best regards,😎

Hello, 

 

Its always advised to reinstall the printer software when one upgrades the OS.

Since you are able to print successfully now, it seems to look good. But in case if you have issues while printing, i'd suggest you to uninstall the existing printer software. Restart the PC and then use the below url to download and install the printer software.
