Abstract: Examples relate to capping stations having caps with positioning mechanism. The capping station for a printing system may comprise a cap to seal a printhead and a positioning mechanism to move the cap between a first cap position and a second cap position.

Abstract: In one example a method comprises causing, by a processor, a nozzle of a printhead to discharge a printing fluid droplet toward a drop detector and receiving, from the drop detector, by a processor, a signal indicative of the location of the discharged printing fluid droplet. The example method comprises determining, by a processor, whether the location of the discharged droplet matches a stored location of the nozzle corresponding to a print mode. The example method comprises issuing, by a processor, a signal based on the determination.

Abstract: In examples, a method includes receiving print image data representing an image to be printed and selectively modifying at least one of an initial background print agent color plane and an initial image print agent color plane to determine a modified color plane.

Abstract: A printer carriage comprises a sensor to be actuated when an actuation member coupled to the sensor contacts a raised portion in a printing target. A vertical position of the actuation member may be adjusted with respect to the printer carriage.

Abstract: A printing device is described. The printing device comprises a fluid flow generator to cause a heating fluid to flow towards a curing zone that is downstream of a print zone in terms of an advance direction of the print medium. The printing device comprises an impingement device arranged upstream of the curing zone in terms of the heating fluid flow. The impingement device is to modify a flow rate of the heating fluid towards the curing zone along the advance direction.

Abstract: Adaptative substrate curing by ejecting a curing flow rate to a curing zone by: heating a heating fluid to a curing temperature; causing the heating fluid to flow along a plurality of serially connected chambers separated being each pair of chambers separated by a heating fluid restrictor, actuating on the heating fluid restrictor as to determine a restricted flow rate between adjacent chambers thereby defining a curing flow rate that passes from the chambers towards the curing zone.

Abstract: Provided is a printing apparatus having a support member with a printhead slot, a first tubing to provide a first printing fluid, and a second tubing to provide a second printing fluid. An end portion of the first tubing is arranged in an active position to provide the first printing fluid to a printhead in the printhead slot. An end portion of the second tubing is arranged in a standby position to not provide the second printing fluid to a printhead. A mechanical structure to which the end portion of the first tubing is attached allows to remove the end portion of the first tubing from the active position and to arrange the end portion of the second tubing in the active position.

Abstract: A printing fluid circulation system is described. The system comprises first and second reservoirs, an outlet to supply printing fluid to a fluid inlet of a printhead, an inlet to receive printing fluid from a fluid outlet of the printhead, and a supply system. The supply system is to operate in a first mode to concurrently supply printing fluid from the first reservoir to the outlet and from the inlet to the second reservoir, and in a second mode to concurrently supply printing fluid from the second reservoir to the outlet and from the inlet to the first reservoir.

Abstract: In one example, a vapor control heater for a printer includes a housing, a heating element at least partially enclosed by the housing, and a fan to move air over the heating element and into a flow of air from the printer dryer.

Abstract: Apparatus for directing air to media. The apparatus including an impinging plate having an array of orifices. The orifices are arranged in a plurality of rows oblique to the direction of motion of the media, and are also arranged to provide air to the media.

Abstract: The present disclosure relates to an inkjet printer 30 including a carriage unit to which a printhead (PT) is coupled, a primary ink tank (T1) and a secondary ink tank (T2) to store ink, and a controller (CT2) to control a pump (PM) so as to cause the secondary ink tank (T2) to supply the primary ink tank (T1) with ink.

Abstract: A printer comprises a printing assembly for printing an image on a print media in a print zone; a cutting assembly for cutting the print media along a contour in a cut zone; wherein the print zone and the cut zone are distinct from one another, one of the zones being downstream of the respective other zone in a print media advance direction; a control unit controlling the printhead assembly and the cutting assembly to perform printing and cutting operations during a single print media feed. A method of printing, using said printer, comprises feeding the print media through the cut zone and through the print zone, in any order; and simultaneously printing an image and cutting a contour while the print media is being fed through the cut zone and through the print zone.

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.
