HP ENVVY Photo 7830
Microsoft Windows 10 (64-bit)

I have HP Pavilion laptop computer running windows 10 (64-bit). After windows 10 feature update version 1903 and subsequent updates the printer (HP ENVY Photo 7800 series) stopped working. Running "HP Print and Scan Doctor 5.3" shows the error "driver conflict detected". I uninstalled the printer software and driver and tried to re-install it. I tried different version of the printer software. It does not seem to work any of them.  Please help.

Hi,

Thanks for using the HP Support Community.


Can you try this:

* *Note that if there are other printers installed, these will need to be reinstalled after this.

Step 1. Uninstall the HP Software from your PC. Please follow the steps provided to uninstall the printer software in the link:

Also, please follow the steps provided below to completely remove the printer software from printer properties.
Steps to remove printer driver files from Print Server Properties:

Step 2. Open the Print Server Properties dialog window by doing one of the following:
• Click the Start menu and in the search field type 'printui /s /t2' (without the quotes), and then press Enter or click it in the search list.
• Open “Devices and Printers” (not Win10)
• Select any printer and then click "Print server properties" at the top of the window.
• Click on the Drivers tab.
• Click on each printer driver and click on Remove

For Win10:
• Press WINDOWS-R on the keyboard to bring up the Run window, type in 'printui /s /t2' (without the quotes), and then press Enter or click OK.
• Click on the Drivers tab.
• Click on each printer driver and click on Remove
• From the Start menu or the Start screen:

Step 5. Right click the Start menu and select Run. Type Services.msc and press OK.
Locate and stop the Print Spooler service

Step 6. Browse to c:\Windows\System32\spool\drivers.
Rename W32X86 to W32x86.oldRename 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 5.

Step 7. Restart PC.

Step 8. Finally, reinstall the HP Software.

Hope that helps!

Hi greenturtle

Thank you very much for your quick reply. I have some questions about your solution. Apart from HP 7800 series printer, the following printers are listed in the "Printer Server Properties":

 

Microsoft enhanced Point and Print compatibility driver x86

Microsoft enhanced Point and Print compatibility driver x64

Microsoft Print To PDF

Microsoft Software Printer Driver

Microsoft XPS Document Writer v4

Send To Microsoft OneNote 2010 Driver

HP PCL3 A-size Printer Class Driver

HP LaserJet Professional CM1410 Series PCL 6

HP LaserJet 5L

HP LaserJet Professional CM1410 Series PCL 6

 

Do I need to remove them all from the list? If so, how do I get them back. Is there a way of saving the drivers and re-install them afterwards?

If I rename the folder W32X86 to W32x86.old and x64 to x64.old, then the some of the above drivers will be lost. How can I get them back?

 

Thank you for your help.
