Details:

The other software product apparently allows to set the jpeg quality when
printing:


print('foo.jpg', '-djpeg100');


but this appears to be a undocumented feature, see
https://stackoverflow.com/a/58305927/3811887

It would be easy to implement this (perhaps we should add it to the "little
project" page on our wiki):
* Parse and validate the quality in __print_parse_opts__.m
* add it to the call of imwrite around line 707. imwrite already supports the
"quality" option.
