Abstract: A print job having a number of pages is printed in a continuous mode, on media advanced at a constant speed. The print job can thus be effectively treated as having a single page. The media that are advanced for printing the print job can similarly be effectively treated as being a single medium.

Abstract: Printers and associated printer maintenance methods and apparatus are disclosed. An example printer includes a nozzle to dispense fluid; a wiper to wipe the nozzle during a maintenance event; and a controller to cause the nozzle to dispense fluid during the maintenance event while the wiping material engages or is immediately adjacent the nozzle to deter a substance from being present within the nozzle.

Abstract: In some examples, dithering based color conversion may include ascertaining an input color value. Based on conversion of the input color value to an output color space representation, a set of nodes that are to be analyzed to control operation of a printer may be determined. Based on a position of the input color value from each node of the set of nodes, a corresponding probability associated with each node of the set of nodes may be determined. Further, the operation of the printer may be controlled based on the determined probability associated with each node of the set of nodes.

Abstract: In some examples, simultaneous color development for thermally activated print media may include ascertaining an input image that is to be printed using a thermal printhead. Colors that are to be printed may be determined for a plurality of specified pixels of the input image. A plurality of frequencies may be clustered to print each color of the determined colors. Based on the clustered plurality of frequencies, operation of a printhead that is to print the plurality of specified pixels may be controlled.

Abstract: In some examples, continuous frequency based print pipeline generation may include ascertaining an input image that is to be printed. For a specified pixel of the input image, a first frequency and a second frequency that respectively correspond to first and second colors may be determined. Based on the first frequency and the second frequency, an intermediate frequency that is to be generated to produce an intermediate color relative to the first and second colors may be determined. The intermediate frequency may be converted to discrete pulses. Operation of a printhead that is to print the specified pixel may be controlled based on the discrete pulses.

Abstract: In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.

Abstract: According to an example, an apparatus may include a fluid coverage engine to determine which pixels of an image are to receive print fluid. The apparatus may also include a pixel count engine to compute a count of pixels at which print fluid is to be applied onto a media from the determined pixels of the image that are to receive print fluid, a target temperature engine to determine a target temperature for a dryer based upon the computed count of pixels, and a dryer engine to cause the dryer to become heated to the determined target temperature.

Abstract: Example implementations relate to wiping die nozzles of fluid ejection dies. For example, a printing device may be directed by execution of stored instructions to eject a droplet in a first direction from an opening in a die nozzle toward a location of an absorbent wipe material and to wipe the opening concurrently with the droplet being ejected from the opening.

Abstract: A method for notification of an error in data exchanged for an application between a client computer telnet and a server computer telnet is disclosed. The error is detected. A message corresponding to the error is generated such that the error message is separate from the data. The error message is handled such that it has priority over the data.
