Unfortunately there is nothing we can do in this situation. The problem that you are experiencing is actually a known problem of the PrintDocument class. If the selected paper size is too large - this results in a silent fail.
you can read about the PrintDocument class. Note the last sentence, at the bottom of the page:
"After calling Print() on a PrintDocument object, if the paper size selected by the user is too large (A2 or larger 16.5 In.x23.4 In.), PrintDocument never fires BeginPrint, PrintPage, or EndPrint events, and no exception is thrown from the Print call. It just fails silently."
