I have a process that captures the pen data, closes the document, prints it (print using Windows driver - no form selected) and saves a copy in a folder (Send to folder).
The printed output contains the ink on white background as it should (the patterns get replaced by the ink), while the saved pdf contains both the ink and the patterns, although it's the same file that gets printed
The process is based on the XAct PP Capture demo (web driven demo).
