Much obliged for your helpful reply. Using multiple RichView controls is

not an option, since all sub-docs would need to be loaded together.

Instead, would it OK to use ContinuousPrint from same RichView. In other

words can I expect reliable results from (pseudo) code below, or must I wait

for ContinuousPrint (async?) method to complete before reloading RichView.

Thanks again...

---------------

Printer.BeginDoc;

RVPrint.StartAt := 0;

RVPrint.AssignSource(RichView1);

RVPrint.FormatPages(rvdoALL);

RVPrint.ContinuousPrint;

for i:= 1 to NumSubDocs do begin

RichView1.Clear();

RichView1.LoadRVFFromStream(NextSubDocStream);

RichView1.Format();

RVPrint.StartAt := RVPrint.EndAt+60;

RVPrint.FormatPages(rvdoALL);

RVPrint.ContinuousPrint;

end;

Printer.EndDoc;
