Hplip users: ============ hpijs does not sem to work with CUPS 1.4.4 Choose the "hpcups" version of the model, e.g.: ---> HP Deskjet 3320 hpcups 3.10.6 (NOT HP Deskjet 3320 hpijs 3.10.6) Hplip users: ============ Avoid sys.log messages such as: " Sep 17 17:03:09 lfs udevd[1138]: SYSFS{}= will be removed in a future udev version, please use ATTR{}= to match the event device, or ATTRS{}= to match a parent " with sed before ./configure: sed -i -e "s/SYSFS{/ATTR{/g" data/rules/55-hpmud.rules sed -i -e "s/SYSFS{/ATTR{/g" data/rules/56-hpmud_support.rules I only spent 2 days on this. -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
