摘要： 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.

摘要： 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.

摘要： An example method for determining an amount of a translucent printing fluid in accordance with the present disclosure is provided. The example method comprises printing a plurality of test patterns with different proportions of colored and translucent printing fluids. The plurality of test patterns comprise a first area and a second area contiguous with the first area, wherein a color of the second area is different from a color of the first area. Migration characteristics of the plurality of test patterns are analyzed to determine an amount of translucent printing fluid to use for a successive printing operation.

摘要： A printer includes a print head to print by ejecting drops of a printing fluid;, a memory to store a correction measure, the correction measure to modify printing a pattern to compensate for decel, and a processor. The processor analyzes print data for a pattern that, when printed using the print head, triggers decel, controls the print head to eject drops of the printing fluid in accordance with the print data, when the analysis indicates that the pattern to be printed triggers decel, applies the correction measure upon printing the pattern, and, when the analysis indicates that the pattern to be printed does not trigger decel, does not apply the correction measure upon printing the pattern.

摘要： In one example in accordance with the present disclosure a device to detect media being wound around a wheel is described. The device includes a reel that collects the media and a movable arm pivotally coupled to the reel to provide tension to the media being wound around the reel. The device also includes a controller that detects media is being wound around the reel by 1) determining an angular position of the movable arm and 2) calculating, based on the angular position of the movable arm, when an output of a motor that rotates the reel is non-zero.

摘要： 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.
