Dear Till, Thanks for the pointer to libcupsfilters, now that issue reported also: https://github.com/OpenPrinting/libcupsfilters/issues/53 (Sadly, my other issues were "declined" upstream. Maybe they know what they are doing...) Thanks, Paul -- Paul Szabo psz@maths.usyd.edu.au www.maths.usyd.edu.au/u/psz School of Mathematics and Statistics University of Sydney Australia
