The HP Laserjet was working normally in Windows 7 Professional and even later after upgrading to Windows 10 64-bit.
The printer suddently stopped working with the following light indication:
- Attention light (A triangle with the exclaimation mark) status: On with solid amber color.
- Ready light (A horse shoe shap) status: Flashing green light.
- Go light (A teal button with diamond shape icon and letter I) status: Flashing green light.
- Printer driver was mysteriously removed.
- Obtain latest Windows 10 64-bit driver: Dot4x64.msi.
However, executing the file does not seem to do anything.
- Attempt to install new driver upd-pcl6-x64-22.214.171.12478.exe file but the DOT4 port cannot be found as like as in Windows 7.
- New toner cartridge has been in use only few times.
- No paper jammed found.
- USB cabled was unplugged/replugged.
- Power was recycled many times.
Please help determine the issue and advise the next course of action.

You installed driver "upd-pcl6-x64-126.96.36.19978" file and no solved your problem, you try uninstall and then reinstall with older driver. It's "upd-pcl6-x64-188.8.131.5262" or "upd-pcl6-x64-184.108.40.20649". You can search and download it at:

I've downloaded and executed the upd-pcl6-x64-220.127.116.1162 driver that you had recommended.
However, the Add New Printer process still cannot find the DOT4 port using the steps below:
Control Panel | View Devices and Printers | Add a printer | The printer that I want isn't listed | Add a local printer or network printer with manual settings | Use an existing port | ...
- LPT 1 - 3
- COM 1 - 4
... but the DOT4 port is not found.

Your problem is driver for your DOT4 port. If yes, you uninstall and then reinstall it.
Go to “Device manager”, click on the View tab, choose “Show hidden devices”.
Then check if there are any USB devices yellow, right click and choose "Update Driver Software", choose windows check auto. If it updated then restart computer, if no change, go to “Device manager” again and chosse “Uninstall”, then restart computer.
Note: You can search driver for your DOT4 port (on Google or anywhere) and install it or key words "DOT 4 port USB" on this forum to solve your problem.
Hope this helps. I'm not work for HP.

It is more likely that the Windows 10 auto update has removed the printer driver which used to work in Windows 7 and then at the initial stage after upgrading to Windows 10.
There is no USB device shown with yellow exclaimation mark.
Uninstall the USB device made the computer hung twice.
I am still searching for the DOT4 port solution in the internet.

Did you solve your problem ? If no, you try install with windows 7 (64 bit) driver for your printer at:
+ Uninstall drivers installed before.
+ Some printers used windows 7 driver on windows 10 and their printer work fine.

After the installation of Windows 7 64-bit printer driver upd-pcl5-x64-18.104.22.16862.exe, I went through the Add a printer process but the DOT4 USB port is still not found.
Thank you for your persistent to help.
