Print-scaling can be turned off for invividual PDF files using Adobe Acrobat, by going to File -> Preferences -> Advanced -> Page scaling. (You can try this using the trial version of Acrobat.)

As for achieving this in code, I've tried and failed to make it work, but the critical difference in the files seems to be:

10 0 obj
<>>>
endobj

for non-scaling PDFs, compared to

10 0 obj
<>
endobj

for those that use the default shrink-to-fit option.
