TRichView assumes that bitmap in OnPrintComponent has the size of the

control, and scales this bitmap according to the printer resolution.

You can create a special RichView item type which will draw itself directly

on printer's canvas, without using temporal bitmaps and without scaling.

Look in the RichView installation, subdirectory

Demos\Addins\ChartItem\

- how to make high-quality printing of TChart, without using temporal

bitmaps and without scaling.
