Do you want to print on the same paper as the old content was printed?
Is the new content added to the end of the document?
YES

After the first print, store the count of items in some integer variable:
LastPrintedItemCount := SRichViewEdit1.RichViewEdit.ItemCount.
When printing next time, assign
SRichViewEdit1.MinPrintedItemNo := LastPrintedItemCount;
Then you can store the count of items in LastPrintedItemCount again, and so on.

The problem has been solved .
I use GetSelectionBounds to get startItemNo,endItemNo.
rve.RVData.GetSelectionBounds(startItemNo,startItemOfs,endItemNo,endItemOfs,false);

Yes, but it may be not what the user expects.
If you use MinPrintedItemNo and MaxPrintedItemNo to print only items belonging to the selection, there will be the following problems:
1) If the item is selected only partially, it will still be printed completely.
2) The selection will be printed at the same position on the page(s) as it is in the original document. But (I believe) the user expects that it will be printed from the beginning of the page.
Currently, the only solution is to create a hidden TSRichViewEdit, copy the selection to it, and then print this hidden TSRichViewEdit.
A code for copying:
Code: Select all
var Stream: TMemoryStream;
if not SRichViewEdit1.ActiveEditor.SelectionExists then
exit; // no selection;
Stream := TMemoryStream.Create;
SRichViewEdit1.SaveRVFToStream(Stream, True);
Stream.Position := 0;
SRichViewEditHidden.RichViewEdit.LoadRVFFromStream(Stream);
Stream.Free;
// now print SRichViewEditHidden
