Yes, I can imagine that if the Canon driver gets a setting that
doesn't make sense to it, it could complain and fail. That isn't
good behavior but some of the drivers do things like this. Why your
app is generating a different value than Preview seems likely to
some old data that is being cached by someone or something: either
a saved print setting you are reusing or a printing preset.
Thanks for the info. I save the print setting with documents via
PMFlattenPageFormat, but for new documents create a new default
format via PMSessionDefaultPageFormat. The problem occurs with new
and old documents and I asked the user to ensure he wasn't using any
presets so I don't think that's the problem.
Is there any process you recommend for flushing any caches that may
be affecting this?
Thanks,
Nick
