Hi, I’m helping someone get printing back on track and have run into a brick wall.
They were able to print up until a few days ago. Well, knowing that they had a lexmark before I tried to disable and remove the lexmark print spooler service. When that didn’t work I decided to try and use Cleanspl.exe to effectively reset the print settings to factory default. Once that was done I tried to have them hook the printer back up…nothing as far as plug and play goes. I downloaded the drivers, installed those and it saw it…but it couldn’t complete the installation. Every time there is a restart or the printer is reconnected there is an error thrown that says “The specified port is unknown.” I have tried to reinstall the printer drivers again, but I think it may have something to do with cleanspl.exe cleaning out either the USB print monitor or something else I need. I have had the user plug something else into USB and it worked perfectly.
