Windows 10: LPT driver broke in 1511

For anyone using the parallel port on their computer for a printer or other device like a lot of restaurants use the printer option, the driver has been broken on the 1511 update.

Workarounds

Enable Legacy PNP devices in the port properties in device manager.

or

disable and reable the port in device manager

or

create a log on script that disables and enables the port using devcon.exe from Windows Driver Kit.

The workaround lasts as long as you dont reboot, if you do the workaround has to be re-applied.

Parallel LPT - How has Windows 10 recently been updated to change the treatment of a parallel port?

Donne,

I have brand new motherboard Asrock AM1B-ITX in my server. I selected it when upgrading to Windows 10. This is one of few that still has LPT port on it. I need the port for my large format printer HP Designjet 3800cp (also 20+ years old). After initial installation
of the Windows 10 and printer driver (used printer driver for Windows 7) all worker great. Few weeks ago after windows update - printer started reporting error when attempting to print. I found out that I can get it to work if I disable LPT port and enable
it back after few seconds. So this may help you a bit - easier than reinstallation.

I think Microsoft broke something in the LPT driver with the update. Hopefully it gets fixed soon.

 

Windows 10 & LPT Parallel Printer Port.

the problem is lpt port is missing on windows 10 . adapter doesnt work because no driver, send driver for lpt

 

I certainly wished I had been aware of this before upgrading my father's computer to Windows 10. The upgrade implements the 1511 update now, so it has this problem. I had assumed it was a problem with the drivers for the printer. instead.

Anyway, if you want to reset the LPT port using the Device Manager each time you boot your computer, probably the easiest way to do it is to go to the "Resources" tab for the LPT port in the Device Manager and un-check, then check (or visa-versa) the "Use automatic settings" toggle, then click "OK". To make it easier on my father, I implemented the script provided by DAC324 in the page banger linked to in the previous post. In my case, the script was as follows:

I obtained devcon.exe by downloading and installing the Windows 10 Driver Kit (WDK). The file was saved in one of the subfolders of the "tools" folder. As DAC324 suggested, I scheduled the script to run upon Windows login. It seems to work so far.
