But that's what I - implicitly - already do:

int page_height = MulDiv(

                    Printer()->PageHeight,

                    Screen->PixelsPerInch,

                    GetDeviceCaps(Printer()->Handle, LOGPIXELSY)

                  );

Here, I translate the page height from printer to screen.

If I use GetTextExtentPoint32() I get a font height of 16 pixels. But on

printing the font height seems to lower to around 14.5 pixels.

The problem is, that I need to include some images with a description

below it. If both picture and description don't fit on the page, I need

to do a page break before. I hoped to achieve this with a method like

the one I showed in my original post.

How do you calculate page breaks in TRVPrint.FormatPages(), if not by

using TRichView.GetItemCoords()?
