I see, well, dont print out sensitive info with 3rd party printers ever.
There are many shops that offer printing services, but one has to be a fool to print out sentitive data with them.
Only use your own printer (not even your neighbors) to print out sensitive data.
I agree, but I think thats where the fear printers might store the data comes from. If someone uses a printer at home and think it might still have sensetive data on it, they could just destroy the printer once its lifetime ended. I also doubt home use printers will have hard disks as they have next to no need to store a large amount of data and it would only increase the price per device.
You can always check the vendor's site and see what specs the printer have, my printer only has a cache that clears every poweroff (worse case scenario after 2 printings).
So if 1 print out a password, I can then print out a photo aftewards and the cache is overwritten.
I`m not sure why any other printer has hard disks, it has no sense, you can just store the config of the printer on your OS with the printing software that you got with the printer. No need to put separate harddisk in the printer itself.
Its very insecure architecture then,
