Printing a single page in this case should be possible by selecting the page in the "Pages" (thumbnails) view, and selecting "print selection" in the print dialog. BUT, unfortunately, there seems to be a bug and this does not work correctly (a page from the first set is printed). I will try to fix this and make the fix available within a week or two.
Other than that, you can of course make your own "print current page" handler, and print the page by taking its metafile and sending it to the print manager, somehow like this:
C1PrintDocument doc = new C1PrintDocument();
// fill the document....
...
C1PrintPreviewControl pview = new C1PrintPreviewControl();
pview.Document = doc;
...
// make a document of the current page:
List<Metafile> doc1 = new List<Metafile>();
doc1.Add(doc.Pages[pview.PreviewPane.StartPageIdx].AsMetafile());
// print it:
C1PrintManager pm = new C1PrintManager();
pm.Document = doc1;
pm.Print(new System.Drawing.Printing.PrinterSettings());
Hope this helps somewhat.
