 From the error messages, I think you are using the
"alternate pdftops filter". I just printed a PDF using
exactly the same options, and it worked.

Do you use the original pstops filter?

To generate debugging output, you might run the
job using the cupsfilter command (don't know if it is
part of the Linux distro - I usually compile CUPS
from the sources).
