Description

Printing liquid supply Background The printing liquid supply includes a reservoir having printing liquid. The printing liquid may be a printing agent, such as ink or any liquid agent that aids in a two-dimensional (2D) or three-dimensional (3D) printing process. In use, printing liquid is provided to the printing liquid dispensing mechanism downstream of the supply. The printing liquid dispensing mechanism may be part of a larger 2D or 3D printing system. The printing system may include a plurality of receiving stations to allow a supply of different liquid types to be connected to the printing liquid dispensing mechanism and to be replaced. Other printing systems, such as monochrome systems, include only a single receiving station. Drawings Fig. 1 illustrates a schematic side view of an example liquid supply apparatus.
