One of the apps I develop, that has not been updated in a year, a new version in the works, suddenly will not print for some users. Multiple reports with screenshots of only my app not being able to print while other apps print fine. It has worked fine for a year+ and has this issue after a Windows 10 update.

The message they get when they try to print is Your printer has experienced an unexpected configuration problem. 0x8007007e

Does anyone know why this would happen and how to fix this issue?

    Hello @RoyLi-MSFT and thanks for replying. We received even more emails just this morning about this issue. This is an app that has run perfectly and the binary has not been updated in the Store for 1 year+. Why would it suddenly not work after the latest Windows 10 update?

    We are working on the next version which has AppCenter but HockeyApp & older AppCenter is what the current version uses. When we developed the last version of the app, AppCenter's Error collecting did not work with Windows 10 yet. So we have no ability in the current version to check on errors. In the soon to be released version this has all been implemented but currently, there is no way to check for errors as HockeyApp is gone.

    I don't have the users' information so I cannot tell you what version of windows but one user said "It appears that my most recent Windows update was on 6/14 with another one scheduled for later today."
    Why would only our app not to print correctly on multiple devices / users? Users are reporting that other apps are printing.

    Thank You
