As per bug #147551, when the default target directory is changed in cups-pdf.conf, cups-pdf silently fails to print anything until a corresponding change is made in the usr.sbin.cupsd AppArmor profile. The ”Out” key in cups-pdf.conf is preceded by commented notes about the usage, but the AppArmor requisition goes unmentioned, apparently causing confusion among users. I suggest something like the attached patch be applied to cups-pdf.conf to document this.
