We are currently using TRIRIGA 10.5.1/184.108.40.206. In IE11, when a record is selected to print, the printer gives a blank page. Whereas before printing, selecting Print Preview shows the page correctly. This behavior was not observed with Google Chrome, where everything gets printed without any issues.
After further investigation, it looks like a Microsoft Windows Update broke this print functionality, and they have since reverted the change that broke it. If you are on the absolute latest IE11 patch, the Print Preview should be working again. Take a look at this blog link. Microsoft has released KB4032782 to address the issue.
