Abstract: In one example, a printer having a removably-installable platen. The platen has a platen type. A surface of the platen has a feature that is indicative of the platen type. The printer includes a single platen-type-discriminating sensor. The sensor detects a distinguishing characteristic of the feature. A controller determines the platen type from the distinguishing characteristic.

Abstract: According to one example, there is provided a printing system. The printing system comprises a print engine to print a print job on media in a print zone, a heating module to apply heat to media in a heating zone and a media handling system to move media through a media path comprising the print zone and the heating zone. The system further comprises a controller to determine when a printing operation is stopped, and when it is so determined to control the heating module to stop heating and to control the media handling system to continue advancing media through the media path until a predetermined condition is met.

Abstract: A drive signal may be determined to drive a printhead to a series of target temperatures during respective portions of a print pass by the printhead. Each of the target temperatures may be the greater of a temperature of the printhead caused by printing a quantity of printing fluid to be printed during the respective portion and a predetermined threshold temperature. A drive signal may be provided to warm the printhead to the series of target temperatures during the respective portions of the print pass.

Abstract: According to one example there is provided a method of adjusting a support structure. The method comprises obtaining a reference orientation of the support structure when the support structure is positioned in a reference position. The height of the support structure is adjusted to a predetermined position and the orientation of the support structure is adjusted such that the orientation of the support structure when in the predetermined position is substantially the same as the reference orientation.

Abstract: A printing fluid cartridge (104) for a pumped printing fluid system containing a pump (110) is described, the printing fluid cartridge (104) comprising a housing (120) defining an interior chamber (122); a collapsible bag (124) within the chamber for holding a supply of printing fluid (126); and a fluid connection member (106) for forming a fluid connection between the collapsible bag (124) and an upstream side of the pump (110). The housing (120) includes a structure allowing the application of manual pressure to the collapsible bag (124) to urge printing fluid out of the collapsible bag through the fluid connection member (106) to the upstream side of the pump (110) to displace air (130) in the fluid connection member (106) and the pump (110).

Abstract: In one example, an apparatus is described, which includes a platen locating the print medium, at least one printhead for marking on the print medium, a carriage holding the at least one printhead, a sensor at least partially mounted to the carriage to measure a printhead-to-platen spacing (PPS) along scanning axis during scanning, and an integrated circuit including a dynamic compensation module and a PPS analysis module to delay firing of printing fluid drops from the at least one printhead to compensate platen defects based on the measured PPS.

Abstract: A method includes identifying at least one of a type of a respective media to be printed on in the print zone and respective densities of portions of the image by an identification module. The method also includes independently adjusting a respective target curing temperature of each one of a plurality of heating modules disposed across the media transport path in a first direction to form the heating zone based on the at least one of the type of the respective media and the respective densities of the portions of the image identified by the identification module by a temperature adjustment module.
