The media management device is arranged to isolate a tension in the continuous print media experienced at the media processing device from a tension in the continuous print media experienced in the external media source.

Abstract: Printing liquid is spat from ai least one printhead nozzle onto a printing medium in a spitting zone when the printhead traverses the spitting zone during printing. The spitting zone is an area of the printing medium located at least partially in a second half of the printing medium in the direction of printhead travel, and wherein a centre point of the spitting zone is located in the second half of the printing medium in the direction of printhead travel.

Abstract: A system is disclosed. The system comprises a roller with a spindle to wind and/or unwind a roll of media, a media advancement sensor to measure the advancement of the media, and a controller. The controller is to control the spindle to rotate an angular displacement, and to determine a calculated media advancement based on the angular displacement and a radius of the roll of media. The controller is also to receive from the media advancement sensor a measured media advancement. The controller is further to detect that a displacement difference between the measured media advancement and the determined media advancement exceeds a predetermined threshold. If the displacement difference exceeds the predetermined threshold a slippage condition is detected.

Abstract: Disclosed herein is a device, a printing device and a method of operating a printing device. The device comprises an air flow path extending from an intake to an outlet. The intake is to be mounted in a printing device and comprises a proximal intake segment and a distal intake segment along the air flow path. A proximal air flow path from the proximal intake segment to the outlet is shorter than a distal air flow path from the distal intake segment to the outlet. Each of the proximal and distal intake segments comprises a wall segment with at least one hole. An opening ratio of an area of the at least one hole and an area of the respective wall segment is larger in the distal intake segment than in the proximal intake segment.

Abstract: In an example, there is provided a method and apparatus for generating a print output file, the method comprising receiving at least one image to be printed, determining a printing area corresponding to a region containing the at least one image to be printed and a non-printing area corresponding to a remaining region, providing a spit-on-page dot pattern limited to the non-printing area, and generating the print output file comprising the dot pattern and the at least one image.

Abstract: In some examples, a first heating stage heats a print medium to a first temperature in a printing region when printing latex ink on the print medium, and a curing heating stage heats, in a curing zone, the print medium to a curing temperature greater than the first temperature to cure the latex ink on the print medium. A cooling stage located between the first and curing heating stages cools the print medium by directing a first part of airflow from the cooling stage to a printing zone, the cooling performed after the print medium has been heated by the first heating stage and prior to heating of the print medium by the curing heating stage. A second part of the airflow is directed from the cooling stage to the curing zone.

Abstract: A primer, a method, and a non-transitory computer-readable storage medium are described. An example non-transitory computer-readable storage medium stores instructions that, when executed by a processor, cause the processor to instruct a printer to advance a media by a first distance. The instructions, when executed, also cause the processor to instruct the printer to advance the media by a second distance different than the first distance to align the media with a cutter assembly. The instructions, when executed, also cause the processor to adapt an interleave mask based on the second distance. The instructions, when executed, also cause the processor to instruct the cutter assembly to separate a first portion of the media from a second portion of the media while the printer is printing on the media.
