Abstract: An electromagnetic filtering system comprising an electromagnetic radiation source, a filter chamber to filter the radiation and a filter chamber control system to selectively modify the contents of the filter chamber in order to modify the wavelengths of the radiation that pass through the filter chamber. There is also provided a method of controlling an electromagnetic filtering system that comprises a controllable filter chamber capable of being controlled so as to selectively be filled with a filter material, the method comprising —determining filtering characteristics to be provided by the filtering system, —determining whether the filter chamber should be filled with the filter material, and —controlling the filter chamber to be filled as determined.

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: In one example, a print head drop detector (202) is described. The print head drop detector (202) comprises a sampling volume and a fan (208) to cause an airflow though the sampling volume (206). Detection apparatus to detect the presence of non-gaseous material within the sampling volume is also provided.

Abstract: In one example, an elevator for a roll of print media includes rotatable shafts oriented parallel to one another and translatable supports to support a roll of print media. Each support is operatively connected to the shafts such that rotating the shafts in a first direction raises the supports and rotating the shafts in a second direction opposite the first direction lowers the supports.
