I have the AppArmor problem with my HP LJ 1012 printer. The aa-complain cupsys freed up the printer. I had no trouble with samba visibility during the time that the printer was shown as stopped (and shown stopped by samba as well as the gnome printer manager. )
FWIW, upon gutsy installation, I couldn't make the printer work until I fetched hplip 2.7.10 from http://hplip.sourceforge.net/ . On the other hand, I didn't know about this aa issue until my 1012 stopped apparently on its own. So it is conceivable that the mere act of installing a new hplip had the effect of resetting aa.
