An optical sensor device () includes an application module () for applying an irregular pattern of marks to a surface of a medium and an optical detector module (). The optical detector module () acquires images of the applied marks and may determine an advancement speed of the medium based on the acquired images.

Applying marks to a surface of a medium

Examples of a media management device for use in a media processing device are described, together with a media processing device for use with a media management device. The media management device supplies a continuous print media to the media processing device, while receiving the media from an external media source. 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.

Media management using a media management device

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.

Aerosol management systems

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.

Method and apparatus for printhead maintenance

A method comprising: soaking a portion of a web in a printing device with printing liquid from a first print head () of the printing device; and wiping at least one nozzle of a second print head () in the printing device with the soaked portion of the web. The method provides a servicing method for print heads in the printing device.

Print head servicing

According to one example, there is provided a system for compensating for changes in printhead-to-printhead spacing in a printing system having multiple printheads mountable on a printhead support. The system includes a measurement system to determine a change in printhead-to-printhead spacing between different ones of mounted printheads, and a processor to determine compensation to be applied to the printing system to compensate for the determined change in printhead-to-printhead spacing.

Compensating for changes in printhead-to-printhead spacing

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.
