Can't install printer driver

Remove the printer from Devices and Printers if it is sitting there.
Now go to Devices and Printers, Printer Server Manager, Drivers Tab and remove the applicable drivers.
Look in Programs and Features for any HP bits and remove these.

Shut down, start up and try installing the printer again.

Please let us know.

Had around 4 printers and I remove all but same problem

1. Did you remove all the drivers?

2. Did you get the newest Windows 10 Drivers for your system. HP put out new Windows 10 drivers AFTER Windows 10 had been introduced.

I have HP 600 series printers running on Windows 10 and HP OfficeJet printers running on Windows 10.  I do not have an HP 400 printer to try.

How can I check in Windows 10 if I removed all the drivers??

Go in device manager??

Here is the page for the LaserJet 400 M401 drivers that include Windows 10 64-bit and 32-bit drivers

How can I check in Windows 10 if I removed all the drivers??

Open Devices and Printers and click once on any printer or printer device. A new Sub Menu opens call Printer Server Management. Click on the Drivers tab and remove applicable drivers.

You can also start Administrative Tools, Print Management and Drivers are in there also.

Ok only 2 drivers not uninstall that is Microsoft enhanced point and print compatibility driver currently in use

No luck
