Desktop: HP Envy 700-214 OS: Windows 10 64 bit Printer: HP LaserJet 4100 (with a USB to parallel cable) I have been able to sucessfully use my LaserJet from Windows 8.1 through my transition to Windows 10 (which I upgraded to about 18 months ago). Fairly recently I allowed Windows to install an upgrade, and at that point I lost my printing ability. It was set to my default printer, but gave an error message when I tried to print. I tried to 'Add a Printer' and selected the HP 4100 connected to LPT1. It wouldn't print a test page, and the printer did not respond as in receiving data. I then tried installing the Universal Print Driver (both PCL6 and Postscript) with similar lack of results.

I have tried uninstallinDeg and reinstalling the drivers, but again no joy. Incidentally, although I go to Device Manager>Print Queues and remove the drivers, when I bring up an application like Word and select the Print Menu, numerous copies of the drivers still remain. When I go to remove them using printui /s /t2, it says that they are in use and can't be removed.

Again, to reiterate - it is not a hardware problem because everything was working fine before Windows upgraded. I just need to find a way to reinstall a driver that will talk to my printer. It's frustrating because I was able to do this before but can't figure out what I am doing wrong.

Thanks in advance. Hello GaryLynn, You seen to have done many things to try solving this issue. However the USB to Parallel is not anHP officially supported connection type. Anyways, What I´d suggest is that you try this: • Unplug the hybrid cable you are using • Uninstall all copies of the printer and its duplicates. • Stop the print spooler by using the services on windows (type on cortana services.msc), locate print spooler and it stop • Go to Run, and type spool, look for the Printers folder and erase all files are in there (if any) • Start the print spooler from services again. • dowload and install this driver package • Power off and on your printer, and plug in the cable.

After this drill, check out if windows 10 was able to locate the best driver to use your printer. If Widows did not automatically find it, try the manual add on Add a printer wizard.
