Abstract: A printing system utilizes printing material cartridges with memory to provide a way to uniquely identify the contents of a printing device cartridge and optimize printing parameters for use with the printing material. Newly developed printing materials and printing solutions therefor can be provided to printing devices that were manufactured prior to the development of the new printing material. Additionally, all cartridges can be physically similar without regard for the type of printing material contained therein, so no special manufacturing is required for each different printing material.

Abstract: Fluid ejection systems and methods thereof are disclosed in the present disclosure. The method includes establishing fluid communication between an ejection chamber and a fluid supply chamber of the fluid ejection system such that the ejection chamber includes a nozzle and an ejection member to selectively eject the fluid through the nozzle. The method also includes detecting at feast one impedance in the fluid by a sensor unit haying a sensor plate, and identifying the characteristic of the fluid by a fluid identification module based on the at least one detected impedance value to obtain an identified fluid characteristic.

Abstract: 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.
