I have seen problems similar to ours but none exact... what is happening is we have a report that has different sections. Text is put into these sections like any normal report. If the text contains any tabs, the last line (or more) is truncated. It prints and previews fine in the JasperViewer. However once converted to PDF, if the tabs are there, we lose at least one line at the end. Remove the tab and it renders fine. We are using Jasper Reports 4.5.1 using SansSerif (which is defined in iReports under Options -> Fonts) Thanks in advance.
