 # HPLIP udev rules file. Notify console user if plugin support is required for this device.
+#
+# SUSE changed:
+#
+# Exchanged the rule to GOTO hpmud_usb_rules if SUBSYSTEM is "usb"
+# with the rule if SUBSYSTEM is "ppdev" to avoid that the "ppdev" rule
+# is needlessly processed when SUBSYSTEM is "usb".
+#
+# Added GOTO hpmud_rules_end rule to skip the hpmud_usb_rules
+# if SUBSYSTEM is not "usb" or if ENV{DEVTYPE} is not "usb_device" or if SUBSYSTEM is not "ppdev"
+# to avoid that the hpmud_usb_rules are needlessly processed.
+#
+# The rule to automatically "check ... plugin status" is disabled
+# because automated installation of non-free proprietary third-party software
+# (here the plugin from HP) should not happen and it can cause whatever kind
+# of strange behaviour see for example https://bugs.launchpad.net/bugs/1197416
+# and https://bugs.launchpad.net/bugs/1221348
+# while in contrast manual printer setup via hp-setup usually "just works"
+# and it is clear for the user what goes on and in case of failure what went wrong.
+#
+# Because the rule to automatically "check ... plugin status"
+# is also used to upload firmware into printers that need it
+# see https://bugs.launchpad.net/bugs/1220628
+# a rule that only uploads firmware into printers that need it is added.
+#
+# If possible activate hpaio backend support in /etc/sane.d/dll.conf.
