See the attachment.

Just to forestall a question I suspect:
the CUPSsetpagedevice stuff in the 1.3.5 variant redefines
the setpagedevice operator to merely collect all the setpagedevice
settings into one single dictionary and execute the real
setpagedevice operator with this dictionary just at the
end of the setop section of the job.
But the result is the save weird output whether or not this
special feature is enabled or not.
