Package: cups Version: 2.3.3op2-3+deb11u1 Severity: important On my Debian machine, files are printed one sided, even though I use Duplex=DuplexNoTumble in my .cups/lpoptions file. I suppose that this is due to the following issue.

So there has been some regression in recent cups versions. -- System Information: Debian Release: bookworm/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-security'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-8-amd64 (SMP w/12 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=POSIX, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages cups depends on: ii cups-client 2.3.3op2-3+deb11u1 ii cups-common 2.3.3op2-3+deb11u1 ii cups-core-drivers 2.3.3op2-3+deb11u1 ii cups-daemon 2.3.3op2-3+deb11u1 ii cups-filters 1.28.10-2 ii cups-ppdc 2.3.3op2-3+deb11u1 ii cups-server-common 2.3.3op2-3+deb11u1 ii debconf [debconf-2.0] 1.5.77 ii ghostscript 9.53.3~dfsg-8 ii libavahi-client3 0.8-5 ii libavahi-common3 0.8-5 ii libc6 2.32-2 ii libcups2 2.3.3op2-3+deb11u1 ii libgcc-s1 11.2.0-5 ii libstdc++6 11.2.0-5 ii libusb-1.0-0 2:1.0.24-3 ii poppler-utils 20.09.0-3.1 ii procps 2:3.3.17-5 Versions of packages cups recommends: ii avahi-daemon 0.8-5 ii colord 1.4.5-3 Versions of packages cups suggests: ii cups-bsd 2.3.3op2-3+deb11u1 pn cups-pdf <none> pn foomatic-db-compressed-ppds | foomatic-db <none> pn smbclient <none> ii udev 247.9-1 -- debconf information: cupsys/backend: lpd, socket, usb, snmp, dnssd cupsys/raw-print: true -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
