Environment
Windows 10 (with the 1803 update)
Micro Focus iPrint Client
Situation
After upgrade Windows 10 to version 1803 (also known as the Windows 10 April 2018 Update), iPrint Direct stops printing. No errors are displayed. Print jobs show a status of Paused.
Resolution
Re-install the iPrint Client
If updating the iPrint Client version (which is an install of the iPrint Client) is an option, that will also resolve the problem. Tools such as ZCM or the iPrint Client Auto Update feature (found in /var/opt/novell/iprint/htdocs/iprint.ini) can be leveraged to help automate the upgrade or re-install process.
Cause
During the update to 1803, Microsoft is removing the iPrint Services (iprntsrv) which breaks the iPrint Direct feature.
