Thank you for contacting us!
We are unaware of any similar issues. Unfortunately, I was unable to reproduce it. I tried this with the Q1 2013 release of Telerik UI for WPF, but everything works correctly on our end.
Could you please try printing from the attached WPF application which has no dependencies on Telerik UI for WPF and let us know how it works?
I am looking forward to your reply.
