Here is this example:

RVPrint.AssignSource(RichView1);

Printer.BeginDoc;

RVPrint.StartAt := 0;

RVPrint.TransparentBackground := True;

RVPrint.FormatPages(rvdoALL);

RVPrint.ContinuousPrint;

RVPrint.StartAt := RVPrint.EndAt+60; // 60 pixels spacing between documents

RVPrint.AssignSource(RichView2);

RVPrint.FormatPages(rvdoALL);

RVPrint.ContinuousPrint;

Printer.EndDoc;

You can set a new page size/orientation for each next richview. But you must

do it before calling FormatPages.

Another approach - using TRVReportHelper. Using this component you have

almost full control on output :

Requires RichView 1.6.54+
