@HV49,

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I understand that you are having trouble installing your LaserJet machine on your Windows 10 PC. I will certainly do my best to help you fix this issue 🙂

To provide you with an accurate solution, I'll need a few more details: 

Have you recently made any changes on the PC before the issue started?

Have you ensured all the drivers are updated either using Windows update or using HP Support Assistant.

Have you tried to do a root level uninstall and reinstall of the printer drivers?

I would suggest you uninstall the printer drivers from the root level and then reinstall them by following the below steps:

• Press “Windows key” + “r” to get the “Run” window.
• Type "services.msc" to get Services – Go to “Print spooler” – Right-click and “Stop” the service.
• Now again open "Run" - Type “spool” and ok - Go to PRINTERS folder - delete everything in that folder.
• Go to services again - Start the print spooler.
• Now check for issue resolution.
• If the issue persists, also try clean installing the printer drivers. Here are the steps:
• First, unplug the USB cable from the printer if present.
• Go to Control panel – Programs and feature – Select all the HP LaserJet printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
• Restart your computer.
• Please click here to download and install the software.
• Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.

If the issue persists, I would suggest you DO THIS DURING THE HP INSTALL PROCESS (when the percentage counter is going)

1. Go into the device manager and find the printer in the list of devices

2. Right click on the printer and select "Update Driver software"

3. Click "Browse my computer for driver software"

4. Select "Let me pick from...."

5. Select the driver named: HP Color LaserJet Pro MFP M477 PCL-6         (Make sure its the one with a dash between the pcl and 6!)

6. Click next and go back to the hp install box and it should now see the printer and continue the install.

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!
