In Google search with communication error 5012 site:launchpad.net and you will get many entries on https://answers.launchpad.net/ and https://bugs.launchpad.net/ The root cause might be a permission problem. By default the USB device node /dev/bus/usb/123/456 should be created by te udev system with this permissions crw-rw-r-- 1 root lp ... /dev/bus/usb/123/456 according to what is specified in /etc/udev/rules.d/55-hpmud.rules Above 123 is the USB bus number and 456 the usb device number which must be replaced with your actual values according to the output of the "lsusb" command. The above permissions are sufficient for plain printing because the CUPS backend which does the actual data transfer to the printer runs as user "lp". In contrast a normal user (e.g. you when you run KDE) has only read permissions which are not sufficient for example to query the device state because for this a device state query must be sent to the device which requires write permissions. Therefore our HAL system should provide read/write access for the normal user who is logged in locally via /usr/share/hal/fdi/information/20thirdparty/70-hpmud.fdi which sets an ACL on /dev/bus/usb/123/456 to grant read/write access only for the one user who is currently logged in locally (i.e. who did log in directly on the computer via graphical login via KDM/XDM). To verify it it is a permission problem, try out if it works as normal user under KDE after you did as root: chmod a+rw /dev/bus/usb/123/456 where 123 and 456 must be replaced with your curretly actual values according to the output of the "lsusb" command for your HP DeskJet 840c (those numbers change whenever you unplug and replug it to the USB). Please report if "chmod a+rw /dev/bus/usb/123/456" makes it work for you. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I wonder if there was no sufficient announcement regarding such a backward incompatible change? Regarding udev: The sane-backends RPM contains /etc/udev/rules.d/55-libsane.rules which has entries of the form (long line is wrapped only here): ------------------------------------------------------------------------ ATTR{idVendor}=="03f0", ATTR{idProduct}=="0011", MODE="0664", GROUP="lp", ENV{libsane_matched}="yes" ------------------------------------------------------------------------ so that an ACL should be assigned. In contrast the hplip RPM contains /etc/udev/rules.d/55-hpmud.rules which has entries of the form (long line is wrapped only here): ------------------------------------------------------------------------ ATTR{idVendor}=="03f0", ATTR{idProduct}=="??11", OWNER="root", GROUP="lp", MODE="664", ENV{sane_hpaio}="yes" ------------------------------------------------------------------------ so that no ACL should be assigned because theere is no ENV{libsane_matched}="yes" for HP devices which also explains why we have bug reports regarding this issue only for HP devices.
