It appears that when Microsoft released Windows 10 Creator it broke Crystal Reports landscape printing (again) in WPF applications. This issue was resolved in (I believe) 13.0.17 but has not reappeared. We use Crystal Reports in a WPF application and if Windows Creator is installed, the report viewer will display the report in landscape, but when you print, the page is portrait and report is landscape, thus over half of the report is cut off. Is this a known issue with SAP? Is there a fix forthcoming? Right now the work around is to install 13.0.20, view the report, save the report as PDF, then print the PDF.
