  • Drum type hard copy apparatus
    Patent number: 6414701
    Abstract: A printing media cartridge for a drum-type hard copy apparatus has printing media supply within the drum. Printable sheet lengths of printing medium are extracted from the interior of the drum through a slot such that individual prints can be produced using the drum outer surface as a platen. Removing a print from the platen extracts the next sheet length from within the drum which is then automatically wrapped back onto the drum's outer surface and aligned for the next print cycle. Printer control encoding is provided with the cartridge.
