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 system includes an image analyzer to analyze an image to be printed by a printer and to obtain an image parameter of the image, and a database to store a plurality of print-mode configurations for the printer. Each print-mode configuration has associated therewith a measure that represents a suitability of the print-mode configuration to print an image having a certain image parameter on a certain print medium. The database receives a query, and the query indicates the image parameter and a print medium. The database selects, responsive to the query and to the measure, a print-mode configuration for the printer, and outputs the selected print-mode configuration. The system modifies the measure associated with the selected print-mode configuration in response to a feedback about the printed image.

Abstract: Certain examples described herein relate to printing systems and methods of operating the same. In an example of a printing system, a porosity determiner determines a porosity of a print medium and a signal generator generates a signal relating to a state of a printing fluid collector based on the porosity determined. In an example of a method of operating a printing system, a pressure measurement is obtained from a vacuum system of the printing system when a print medium is present on a media path of the printing system. This is compared to at least one predefined pressure range and, based on the comparison, an indication is provided setting out a state of a printing fluid collector.

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.
