    I have a problem in my app.
    I will explain it very simple: when I want to print out a box on the printer the size is not exact 200mm but 199,3mm. THis is not much, but it is important for my app.
    This behaviour is on many printers (maybe on every printer).

    To set the map mode I use
    SetScrollSizes(MM_LOMETRIC,...) in OnInitialUpdate().

    Is this a problem of the printer? is it not good enough?
    Or do I miss to set something in the code?
