Abstract: Examples relate to receiving image data of an image to be sublimation printed, wherein the image data comprising one or more colours to be printed, and a corresponding printing liquid density of the one or more colours. Based on the received image data, a sublimation energy to use to transfer printed printing liquid representing the image into a material is determined, and the determined sublimation energy is provided to a sublimator of a printer for transferring the image.

Abstract: The present disclosure relates to methods and devices for performing print control. In an example there is disclosed a control method. The control method may comprise programming a print mask to instruct printhead nozzles on a moveable carriage to deposit a first line of print material on a medium, wherein the print mask controls the depositing so that an edge of an area of the medium on which material is deposited defines a pattern which is repeated along a scan axis of the carriage and which differs in a direction of movement of the medium. The control method may further comprise scanning the first line of print material. The control method may further comprise performing control of subsequent print material depositing or medium advancement, based on the scan.

Abstract: A method to control a printer carriage in which the printer carriage is controlled to move along a first axis at a first predetermined speed when a printhead, installed on the printer carriage, is ejecting printing fluid in a print zone. The printer carriage is moveable bidirectionally along the first axis in swaths to enable the printhead to print in the print zone. The printer carriage is also controlled to move along the first axis at a second predetermined speed, higher than the first predetermined speed, when the printhead is not ejecting printing fluid in the print zone.
Abstract translation: 一种控制打印机托架的方法，其中当安装在打印机托架上的打印头正在打印区域中喷射打印流体时，打印机滑架被控制成以第一预定速度沿着第一轴线移动。 打印机托架可沿着第一轴沿双向移动，以使打印头能够在打印区域中进行打印。 当打印头不在打印区域中喷射打印流体时，打印机托架也被控制为以第一预定速度高于第一预定速度的第一轴线移动。

Abstract: In example implementations, a method, a device, and a program are provided. The method includes detecting a power increase movement of a printer carriage. A location of the printer carriage is detected at a time of the detected power increase. Based on the detected location of the printer carriage, determine whether the print medium is damaged. The device includes a power monitor to detect a power increase during movement of a printer carriage. A locator detects a location of the printer carriage at the time of the detected power increase. A damage determiner determines, based on the detected location of the printer carriage, whether the print medium is damaged. The program detects a power increase during movement of a printer carriage. Location of printer carriage is detected at time of detected power increase. Based on detected location of the printer carriage, it is determined whether the print medium is damaged.

Abstract: Aspects of the disclosure provide an electronic device comprising a controller. The controller to determine a volume of print fluid in a first tank of the electronic device, monitor current printing conditions of the electronic device disposing print fluid on a substrate, determine, based on the volume of print fluid and the current printing conditions, whether an adverse printing condition exists, responsive to the volume of print fluid being less than a threshold and the adverse printing condition not existing, control a pump to refill the first tank from a second tank at a flow rate determined at least partially according to the determined volume, and responsive to the volume of print fluid being less than the threshold and the adverse printing condition existing, control the pump to refill the first tank from the second tank at a default flow rate determined independent of the determined volume.

Abstract: In certain examples, a printing device comprises a print head, a dryer, a heat exchanger, a distribution system and a controller. The heat exchanger is coupled to an exhaust of the dryer to produce pre-heated air. The distribution system is coupled to the heat exchanger and a plurality of regions of the printing device. The controller causes the distribution system to distribute the pre-heated air from the heat exchanger among the plurality of regions based on an operating parameter of the printing device.

Abstract: A cleaning module includes an actuator device, a fluid chamber, and a wiper member. The actuator device may enter an activation state based on a movement of at least a portion of the actuator device in response to an engagement with the printhead. The fluid chamber may store and supply fluid to the porous wipe material in response to the activation state of the actuator device. The wiper member may apply pressure to a porous wipe material including the fluid therein to wipe the printhead.

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.
