This problem seems to be found and solved upstream. This is the relevant link http://www.cups.org/str.php?L1528+P0+S-2+C0+I0+E0+Q There is a patch that has been incorporated in 1.2-current (SVN: v5362) By the way both bugs 372586 and 373839 seems to be the same. I guess one should merge them. Best regards. Quim
