I have a HP LaserJet 1012 printer that I want to sell. But before I do that I want to completely wipe its memory. Do you guys have any experience with this? I don't know its complete specs, but I believe it has 8 MB of ram. If this is the same ram as computer ram, isn't the act of just shutting the printer off good enough or is there something else I need to do? Is there some persistent memory in the printer some where? Thanks.
