Abstract: A printing apparatus is disclosed herein. The apparatus comprises a first carriage, moveable along an axis, comprising a first print agent dispenser to selectively eject a first set of print agents; a second carriage, moveable along the axis, comprising a second print agent dispenser to selectively eject a second set of print agents to the build material layer; and a controller. The controller is to receive data corresponding to a print job; determine a first amount of the first set of print agents and a second amount of the second set of print agents to be ejected at a print area based on the received data; determine a first delay between the ejection of the first amount of the first set of print agents and the second amount of the second set of print agents at the print area; and to independently control the movement of the first and second carriages and the ejection of print agents from the first and second print agent dispensers based on the determined first delay to generate the print job.

Abstract: In an example, a valve for a printing fluid supply system is disclosed. In this example, the valve includes two rigid shells to provide connections to a first printing fluid supply cartridge, a second printing fluid supply cartridge and a printhead. Further, the valve includes a diaphragm with sealing elements disposed between the two rigid shells to selectively couple one of the first printing fluid supply cartridge and the second printing fluid supply cartridge to the printhead and seal other printing fluid supply cartridge using the sealing elements.

Abstract: In certain examples, a printing system comprises: a carriage guide extending in a longitudinal direction; a printer carriage movable, in use, along the guide; and at least one bearing to direct motion of the carriage along the carriage guide. The at least one bearing is movable, relative to the carriage guide and laterally to the longitudinal direction, from a first carriage guide contact position to a second carriage guide contact position.

Abstract: An example in accordance with an aspect of the present disclosure includes an ink channel of a printer, coupleable to an ink supply to receive an ink. A sensor assembly is mounted to the ink channel, including a sensor in fluid communication with the ink channel to identify an ink level of the ink supply based on a pressure difference between an air pressure, associated with the sensor assembly, and an ink pressure, associated with the ink channel.
