The fundamental problem is that the printer crops the image so that not everything that ought to be printed actually appears on the page; the cropping appears to be about 10 to 15 points (a little more than an

CUPS (and Ghostscript) do not support DeviceAdjustMatrix (which AFAIK
is not a standard attribute).

Your problem is likely either with the Ghostscript driver you are
using, the language support in the printer, or a hard limit in the
printer itself.
