   Well I follow your advice and change the media size to CD - Custom,
   that solved the size problem.  I'm still having problems centering
   the image, as I thought its a margin problem.

   When printing to the box of coordinates (0px,0px) and size (1675px,
   1675px) The image was off by approximately 5.3mm, because my image
   has 360DPI i decided to print to the box of position (-75px,-75px)
   and size (1675px,1675px) which ended up with a offset of 3mm in the
   other direction.  Because I couldn't explain this behavior I
   decided to divide mi offset by half and print to the position
   (-35px,-35px) and that worked pretty good.  So can someone explain
   me what are the default margins and why my calculus where so wrong?
   1inch is 25.4mm so 5.3mm are 0.208661417323inch, multiplied by 360,
   75.12px

The default margins for printing to a CD should be zero all around.

Is the central hole positioned correctly or not?

What happens if you use CD - 5 inch?  I suspect this may be a CUPS
interaction; CD - 5 inch will avoid it.
