System admins discovered that many PCs suddenly couldn’t connect to printers
As if an actively exploited critical flaw in the Windows Print Spooler that can allow someone to take over your computer remotely isn’t bad enough, some people who installed Microsoft’s security patch found out that the connection to their printer stopped working. In a near-repeat of a problem that occurred this spring with a different Windows 10 security update, system admins discovered that many PCs suddenly couldn’t connect to printers — most notably several models of Zebra label printers — after installing the KB5004945 patch.
Microsoft has acknowledged the problem as a known issue that can be solved by rolling back the patch or reinstalling the printer as an administrator.
In a statement to The Verge, Zebra acknowledged the problem and said Microsoft plans to release an updated patch in the next couple of days that should address the issue.
