    Abstract: In one example, a system with a fluid level detector includes a fluid actuator assembly with a fluid chamber and a fluid container (40) with a fluid reservoir (44) coupled to the fluid chamber (22). A pressure regulation bag (42) is disposed within the fluid reservoir (44) along with a fluid level sensor (60) to provide an estimate of a fluid level in the fluid reservoir. The fluid level sensor (60) is disposed such that when the fluid reservoir (44) contains fluid, the fluid is not detected in contact with a top of the fluid level sensor once the pressure regulation bag is at a regulation point. When the pressure regulation bag (42) is maximally inflated to fill the fluid chamber (22) with the fluid, the estimate of the fluid level represents a measurement of an amount of fluid in the fluid reservoir (44) once the pressure regulation bag returns to the regulation point.

    Abstract: A printing fluid container (100) for use in a printing system is described. An example container includes a base (110) and a light transmissive side wall (120). The side wall extends from the base to define a chamber (130) for receiving and storing printing fluid within the container. The side wall has an internal surface (122) facing the chamber, said internal surface comprising a channel (140). The channel comprises a portion (142) indicating a height from the base, the height representing a predetermined fill amount. The channel is configured such that when the chamber contains printing fluid, printing fluid resides within the channel (140) and indicates the predetermined fill amount.

    Abstract: In examples a printing system comprises a controller and a printing device. The controller is to divide a print job into a sequence of areas, wherein an image property varies between adjacent areas. The controller is to determine a pausing point to be within a runout area at which a remaining amount of a consumable will be at or below a predetermined first amount when executing the print job when the runout area fulfills a condition. The controller is to determine the pausing point to be within a preceding area that fulfills the condition when the runout area does not fulfill the condition. The controller is to control the printing device to pause printing of the print job at the pausing point.
