Nothing earth-shattering but... I have an HP Photosmart USB printer that I configured with HPLIP (which seemingly "exports" into CUPS). All is well until the printer is turned off and then back on again sometime later: somebody, somewhere automagically adds the printer to CUPS so that I have two, count 'em, printers defined.

What the heck!
Did I miss something somewhere? Some UDEV rule, some other thing?
