I have to answer myself as I have found a way to work around the wrong 
measurement. Sizes are ok now, but the print is still not turned by 90° 
for Landscape.

The whole thing is somewhat strange as I use the same code in another 
program to compute the positions for printing.

How do you calculate mm to printing pixels?
