Microsoft confirmed that updates the company delivered this week as part of the November 2017 Patch Tuesday are causing Epson dot matrix printers to malfunction.
The issue was reported computer support forums across the Internet. All affected users reported the same thing —not being able to start print jobs because their computers do not recognize Epson dot matrix printers connected via USB cables.
Günter Born, an engineer from Germany, tracked down these issues to recent Patch Tuesday updates:
KB4048953 for Windows 10 Version 1607
KB4048954 for Windows 10 Version 1703
KB4048955 for Windows 10 Version 1709
KB4048956 for Windows 10 Version 1507
KB4048957 for Windows Server 2012 R2
KB4048958 for Windows 8.1
KB4048959 for Windows Server 2012
KB4048960 for Windows 7 SP1
Microsoft confirmed the cause of Epson malfunction in an update added to the official KB support pages, yesterday.
"After installing this update, some Epson SIDM (Dot Matrix) and TM (POS) printers cannot print on x86 and x64-based systems," the company said.
"Microsoft and Epson have determined the cause of the issue and are working on a solution. This problem is not related to the printer driver, so installing current or older print drivers will not resolve the issue," Microsoft added.
The Redmond-based OS maker promised to provide a future update to fix the problem.
Users can still use their printers if they uninstall the faulty updates. Born recommends running the following command in a cmd.exe window (using Run as administrator):
wusa /uninstall /kb:xxxxxx /quiet /warnrestart
, where xxxxxx is the number for the faulty KB updates.
