Abstract
A print supply, the print supply to connect to a printing device to provide a print material to the printing device that includes a fluidic bag within a box to maintain a print material supply, a machine and human readable fluid gauge system that includes a microprocessor to transfer print material level information describing a level of print material within the bag, and a gauge display to represent the level of print material within the bag, and a near field communication device to transfer data describing a level of print material within the print liquid supply.
Claims20
A print supply, the print supply to connect to a printing device to provide a print material to the printing device, comprising:
- a fluidic bag within a box to maintain a print material supply;
- a machine and human readable print material gauge system, comprising:
- a microprocessor to transfer print material level information describing a level of print material within the bag;
- and
- a display to represent the level of print material within the bag;
- and
- a near field communication device to transfer data describing a level of print material within the print supply.
A replaceable printing fluid supply, comprising:
- a container to hold a volume of printing fluid;
- integrated circuitry to interface with a printing device;
- and
- a machine and human readable fluid gauge system communicatively couplable to the printing device via a near-field communication device to receive fluid level data describing the level of fluid within the container and, via a microprocessor, present a fluid level indicator on a display of the fluid gauge system.
A fluid supply level indicator, comprising:
- a microprocessor to interface, via a near-field communication device, with a printing device;
- and
- a display to optically represent data describing a fluid level within a fluid supply coupled to the fluid supply level indicator, the microprocessor to control the display based on data received by the microprocessor from the printing device via the near-field communication device that describes usage by the printing device of fluid from the fluid supply.
