I've got a Windows 2016 print server. It hosts some Xerox copiers, older HP Laserjet printers using native drivers, and new HP Laserjet printers using the HP universal driver.
The clients are a mixture of Windows 10 and MacOS Big sur.
I installed the September cumulative quality update and many of our users are unable to print. All of the MacOS users for sure and they are the majority of users. I had to uninstall the patch (KB5005573 and KB5006669) to allow printing to resume.
So I'm not sure where to go from here. I found many articles talking about registry hacks to bypass the changes, but they have not worked on my test print server.
if someone could help me with the correct registry changes to remove the new changes and allow the Print nightmare vulnerability, that would be a start.
But then at some point I need to fix the server so we can do network printing in a secure way. I haven't really seen anything about this. I looked at the Xerox site and the newest Color C70 driver for Windows is from 2016? So what do I do?
