Thank you DELBEKE,

    Note that :
    PrnWidth = GetDeviceCaps(Dc, PHYSICALWIDTH)
    PrnHeight = GetDeviceCaps(Dc, PHYSICALHEIGHT)
   
    return the actual paper's width/heigth , not the printable area.

After doing some further research:
    PortraitOffsetX = GetDeviceCaps(Printer.hDC, PHYSICALOFFSETX)
    PortraitOffsetY = GetDeviceCaps(Printer.hDC, PHYSICALOFFSETY)
 
    return the real printer offsets from top and left (ie. the position where the printer can start
     printing)
    the measurement  returned in Device Units which is essentially DU = dpi*inches
    So we have to know our printer's dpi to calculate our document in inches/milimeters
    This is achieved by :
    CPrintDialog dlg(FALSE);
    app->GetPrinterDeviceDefaults(&dlg.m_pd)
    LPDEVMODE devmode = dlg.GetDevMode();
    short dpi = devmode->dmPrintQuality;

You can use Wndows apis to find printer margins
    PortraitOffsetX = GetDeviceCaps(Printer.hDC, PHYSICALOFFSETX)
    PortraitOffsetY = GetDeviceCaps(Printer.hDC, PHYSICALOFFSETY)
    PrnWidth = GetDeviceCaps(Dc, PHYSICALWIDTH)
    PrnHeight = GetDeviceCaps(Dc, PHYSICALHEIGHT)

Good Day,

I am using QuickPDF to print some engineering manuals where precision matters.

So when i print a PDF i cannot use the "Page Scaling" option because then the printed dimensions will not be accurate.
The solution is to find the printer margins, and create a cropBox not containing them.
Ideally i would like to make my application print correctly in different printers.
My question is:  Is there a way to find the printer Margins using QuickPDF?

Thanx in advance,

Stakon.
