Home Forums Networks & Cross-Platform Networking printer rumbling

OS 10.6.8 HP Officejet 4620 I have not used my printer for over 2 weeks. I downloaded LS july 5th and yesterday and today when I was checking my mail, the printer actually rumbled for several seconds (still switched off) with a noise I've never heard before. Could there be any connection because of LS? Could any of the deny or allow decisions affect the printer? jaybass
