This problem was noticed when the utility was first released and threads are
at:  http://www.luminous-landscape.com/forum/index.php?topic=49209.0  and
http://forums.adobe.com/message/3309536#3309536 The resizing issue was noted
but I don't know whether it was ever resolved since it only appeared to be
happening sporadically.  It may be for some measuring instruments that the
tolerance is so close that slight shrinkage causes a misread.  I profiled
all my papers using an i1 Pro with ArgyllCMS generated targets from a Win7
machine using the Adobe Utility and did not get any misreads.  The measured
patch size from 'printtarg' was 12x8 mm for the print utility.  I did not
print targets out from Photoshop CS5 to compare the measurements since CS5
cannot be used for target printing without a work around and the utility
worked fine for me.

I know this doesn't answer Philip's particular issue and perhaps reposting
this to Adobe may help out.

        that's rather a problem, since the sole purpose of Adobe C.P.U.
(ACPU) is
to print test charts ! Have you tried altering the page margin that
allows, using the -m parameter ? It's possible that ACPU is scaling the test
chart to fit it within the printable area (although this would be unhelpful
behavior for a test chart print application - it should always crop rather
than scale).

Perhaps it's worth raising this issue with Adobe on one of
their forums, or on the Apple Colorsync list ?
