Abstract: Priming printheads can, in various examples, include moving a movable member of a printhead from a first position to a second position, measuring a response time of the movable member to move from the first position to the second position, and identifying the printhead as primed.

Abstract: Ambient temperature based flow rates can in an example include a setting a flow rate of ink to a printhead mounted in a carriage based on an ambient temperature associated with the printhead, measuring a flow rate of ink to the printhead, and causing a decrease in a velocity of the carriage in response to the flow rate of ink satisfying the threshold flow rate.

Abstract: Printhead priming can, in various examples, employ a conduit and a divider such that a predetermined portion of a pressurized gas in the conduit is provided to an environment surrounding the divider and a remaining portion of the pressurized gas in the conduit is provided to a printhead at a pressure sufficient to prime an ink supply.
