Re: [cups-devel] What would be the best way to internally scan before deliver to CUPS.

Not for Mac OS but for Linux, nevertheless some basic
ideas therein might also be applicable on Mac systems:

https://en.opensuse.org/SDB:Using_Your_Own_Filters_to_Print_with_CUPS

Therein see in particular the sections
"Adding Additional Filter Stages to the Default CUPS Filter System"
and
"Print Job Data Specific Custom Filters"

Those additional filters would run by CUPS so that
print jobs must have been already deliverd to CUPS
so that this is not "scan before deliver to CUPS"
but "scan by CUPS before deliver to printer".

I think on Mac OS CUPS is running in a "sandbox" which
may not allow to run additional selfmade filters.
