I also noticed the restrictive permissions and then found this bug report. Changing the permissions back to 755 does allow printing to work again,but the changelog <http://packages.debian.org/changelogs/pool/main/c/cups-pdf/cups-pdf_2.5.0-15/changelog#versionversion2.5.0-15> considers this a fix. More explanation on why this is
necessary would be welcome.
For now, I see no other choice but to change the permissions back to what they were. Dale
