摘要： A replaceable printer component includes a memory device to store a tag encryption mask and data. The data is stored in a plurality of blocks of the memory device wherein each block is defined by a tag. The tag encryption mask indicates an encryption status of each block of the memory device defined by the tag. The replaceable printer component includes a communication link to communicatively link the memory device to a printer controller when the replaceable printer component is installed in a printing system. The tag encryption mask is stored within a header of the memory device. Each tag defines a type and a length of the data stored in the blocks.

摘要： A method for tuning ink usage includes storing an ink usage adjustment value in a memory of an ink cartridge; and with a printing system utilizing the ink cartridge, adjusting an ink usage of the ink cartridge based on the ink usage adjustment value. An ink cartridge includes a memory for storing an ink usage adjustment value, the ink usage adjustment value based on ink usage properties of the cartridge. A printing system utilizing the ink cartridge adjusts an ink usage of the ink cartridge based on the ink usage adjustment value.
