Well, theoretically it's possible to set all RVPrint's margins to 0 and use

only TRichView's margins (modified by TRVRuler). The only problem is taking

"physical offsets" into account - outermost areas on paper where the printer

cannot print.

But I am not sure if it makes sense. WYSIWYG printing is not supported yet,

documents cannot be displayed in the editor exactly like on the page. Only

an approximation is possible. Taking it into account, plus impossibility of

zooming in editor, I do not understand why users may need large margins in

TRichViewEdit.

It's possible to force TRichViewEdit to use the fixed screen resolution, for

example 96.

You can do it by assigning

RichViewPixelsPerInch := 96; // defined in RVFuncs unit

RVStyle1.TextStyles.PixelsPerInch := 96;
