Abstract: Certain examples relate to mixing and/or supply cartridges for printing apparatus. One example implementation includes a reservoir to receive printing material from a printing apparatus and to return the received printing material to the printing apparatus. A storage medium stores a reservoir printing material level parameter indicative of the amount of printing material in the reservoir; a recirculation cycle counter indicative of the number of recirculation events experienced by the cartridge; a maximum recirculation cycle parameter indicative of the maximum number of recirculation events that may be experienced by the cartridge.

Abstract: A printing device and method is described comprising: selectively generating a negative fluid pressure between one of one or more printing fluid supplies and a first one of first and second ports of a printhead; selectively generating a positive fluid pressure between one of said printing fluid supplies and a second one of the first and second ports of the printhead; and providing a first pulsed signal to a first priming pump associated with a first one of the first and second ports, wherein the first one of said first and second ports of the printhead is opened under the control of said first priming pump, such that printing fluid within the printhead exits the printhead through the first one of the first and second ports.

Abstract: A system includes an image analyzer to analyze an image to be printed by a printer and to obtain an image parameter of the image, and a database to store a plurality of print-mode configurations for the printer. Each print-mode configuration has associated therewith a measure that represents a suitability of the print-mode configuration to print an image having a certain image parameter on a certain print medium. The database receives a query, and the query indicates the image parameter and a print medium. The database selects, responsive to the query and to the measure, a print-mode configuration for the printer, and outputs the selected print-mode configuration. The system modifies the measure associated with the selected print-mode configuration in response to a feedback about the printed image.

Abstract: An example printing fluid circulation circuit for a printing system comprises a first circuit port to supply printing fluid to, or receive printing fluid from, a first fluid port of a printhead and a second circuit port to supply printing fluid to, or receive printing fluid from, a second fluid port of a printhead. The printing fluid circulation circuit is to operate in a first mode to concurrently supply printing fluid from the first reservoir to the first circuit port and from the second circuit port to a second reservoir, and in a second mode to concurrently supply printing fluid from the first reservoir to the second circuit port and from the first circuit port to the second reservoir.

Abstract: In an example, a pressure system includes a fluid movement device, a buffer reservoir coupled to the fluid movement device, and a first fluid interface coupled to the buffer reservoir. In that example, the first fluid interface is able to couple to a pressurizable chamber of a print fluid container (that can apply force on a print fluid bag of the print fluid container).

Abstract: Certain examples relate to controlling recirculation processes in a printing apparatus. An example printing material cartridge includes a reservoir storing printing material to supply a printing apparatus; memory; and instructions for controlling a recirculation process in the printing apparatus, the instructions stored in the memory, the recirculation process to cause the printing material to move between the reservoir and a second printing material cartridge, the second printing material cartridge separately replaceable from the printing material cartridge in the printing apparatus.
