    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 system includes a first circuit to circulate a printing fluid through a printhead in a first direction and a second circuit to circulate the printing fluid through the printhead in a second direction opposite to the first direction. The first circuit is activated during a first mode to circulate the printing fluid from a first reservoir to a second reservoir. The second circuit is activated during a second mode different from the first mode to circulate the printing fluid from the first reservoir to the second reservoir.

    Abstract: In an example, a printer controller is coupled to a fluid pump, a primer pump, and a pressure sensor of a printer, wherein a flow channel provides a fluid communication between the fluid pump and the printhead for enabling fluid recirculation in the printer. The printer controller: activates the fluid pump; activates the primer pump for a first predefined time interval; and identifies or determines a movement of fluid in the flow channel based on the fluid pressure measured by the pressure sensor.

    Abstract: A printing fluid cartridge (104) for a pumped printing fluid system containing a pump (110) is described, the printing fluid cartridge (104) comprising a housing (120) defining an interior chamber (122); a collapsible bag (124) within the chamber for holding a supply of printing fluid (126); and a fluid connection member (106) for forming a fluid connection between the collapsible bag (124) and an upstream side of the pump (110). The housing (120) includes a structure allowing the application of manual pressure to the collapsible bag (124) to urge printing fluid out of the collapsible bag through the fluid connection member (106) to the upstream side of the pump (110) to displace air (130) in the fluid connection member (106) and the pump (110).

    Abstract: Certain examples described herein relate to printing systems and methods of operating the same. In an example of a printing system, a porosity determiner determines a porosity of a print medium and a signal generator generates a signal relating to a state of a printing fluid collector based on the porosity determined. In an example of a method of operating a printing system, a pressure measurement is obtained from a vacuum system of the printing system when a print medium is present on a media path of the printing system. This is compared to at least one predefined pressure range and, based on the comparison, an indication is provided setting out a state of a printing fluid collector.
