You have correctly noticed the change. We have tried to improve the printing behavior so that the user does not have to manually switch the default page orientation of the printer. This comes with some custom logic and apparently you have hit a glitch it it (we confirm the problem). The issue will be logged and fixed in a subsequent version of the product. Meanwhile if you manually set the correct page orientation the report should be printed as expected.
We are sorry for the inconvenience. Your Telerik points have been updated for letting us know about this problem.
All the best,
the Telerik team
