Hi Stefan and everyone,
Using a Delegs program, a Deaf student played with and wrote several words and then printed a document.  You will find an attached document (SCAN 0001 jpg).  Look at the page.  At the top, this page shows features (new, save as, create PDF, signwriting line, search word line, and free text line). You will notice that some SignWriting symbols and some words are missing on the right side of this page. 
Stefan, I have a question for you:  Is your printed document similar to this page?
Best regards,
