Windows Update[German]Microsoft has released update KB4055038 for several Windows versions. This update intends to fix the Epson dot matrix printing bug, that prevents printing from Windows after installing November 14, 2017 patches.


What's the problem?

Microsoft has issued several security updates for Windows 7 up till Windows 10 at patchday November 14, 2017. Users who has installed these updates are facing a strange issue. Epson dot matrix printers and POS printers was not able to print under Windows.

I've addressed this issue within my blog post Microsoft confirms Epson dot matrix printer issue after November 2017 patchday: here are fixes – and proposed several fixes.

Windows update KB4055038 fixes printing bug

Microsoft released update KB4055038 on November 21, 2017 for Windows 7 SP1, Windows 8.1, and Windows Server 2008, and Windows Server 2012 (and the R2 pendants). According to Microsoft this update fixes the printing issue.

This update addresses an issue that prevents some Epson SIDM (Dot Matrix) and TM (POS) printers from printing on x86-based and x64-based systems.

The new update fixes systems that has been affected by the following November 14, 2017 updates.

  • 2017-11 Monthly Rollup – KB4048958 (Windows 8.1, Windows Server 2012 R2 Standard)
  • 2017-11 Security-only update – KB4048961 (Windows Server 2012 R2 Standard, Windows 8.1)
  • 2017-11 Monthly Rollup – KB4048957 (Windows 7)
  • 2017-11 Security-only update – KB4048960 (Windows 7)
  • 2017-11 Monthly Rollup – KB4048959 (Windows Server 2012)
  • 2017-11 Security-only update – KB4048962 (Windows Server 2012)

The update is delivered via Windows Update, but a manual download via Microsoft Update Catalog is possible.


If you have uninstalled the updates listed above to fix the issue, re-install these updates. Then install Update KB4055038 under Windows 7, Windows 8.1 and the related Windows Server versions. Then Windows should be able to print to the dot matrix printers again. I haven't found a similar update for Windows 10.

Note: My suggestion is, to wait a few days and see, if this update is causing some collateral damages. I got a German comment, that installing this updates requires several reboots and took a long time. And I recogniued a comment, that the update is blocking another printer.
