Abstract: An example printing apparatus is described comprising a wiping element before the print zone, for slipping in contact with a print medium and wiping a printing surface of the print medium. An implementation of a wiping roller for wiping the printing surface of a print medium may comprise a rigid core, a layer of elastic material and a driving pinion. An example method for printing is also described, comprising spreading over a larger print medium area, by wiping, amounts of a substance that may migrate through a print medium and that is present on the printing surface of a print medium, before printing on the print medium.

Abstract: Herein, techniques are described for printing an image on a print media by operation of a printhead to eject a print fluid over the print media. In at least some examples, a printhead temperature parameter is acquired, the parameter being indicative of a temperature at the printhead during printing; alignment of the printhead is corrected based on the printhead temperature parameter; printing is performed on the print media via the printhead according to the corrected alignment.

Abstract: In the field of printing technology, non impact printing methods such as inkjet printing may be used to deposit an ink composition onto print media to form an image. An ink composition typically comprises a colourant material and a vehicle, such as an aqueous solution, for delivering the colourant material to the print media. A wide range of such ink compositions is known in the industry. It is also known to use various pre-treatment compositions in combination with ink compositions in order to enhance the quality of a final image. Pre-treatment compositions are often substantially colourless liquid compositions that interact with elements of the ink composition to fix colourant to the print media. Pre-treatment compositions may help to improve image quality for example by reducing image bleeding, edge roughness and other image quality issues.

Abstract: According to one example, there is provided a method of controlling a printing system. The method comprises: obtaining a print job to print on a substrate; obtaining a value of a factor material to an undesirable condition occurring; determining a quantity of printing fluid to be deposited on a substrate when printing a portion of the print job; determining, based on the obtained value and the determined quantity of printing fluid to be deposited, whether the undesirable condition is likely to occur whilst printing the portion of the print job; and temporarily reducing the throughput of the printing system whilst printing the portion of the print job where it is determined that the undesirable condition is likely to occur whilst printing the portion of the print job.

Abstract: In some examples, a system detects an error in an printing device, and selects a combination of a medium advance error correction process to address a medium advance error and a faulty nozzle correction process to address a faulty nozzle, where the selecting of the combination is from a plurality of different combinations of the medium advance error correction process and the faulty nozzle correction process, and the selecting is based on a criterion relating to an interaction between the medium advance error and faulty nozzle correction processes.
