Abstract: A deposition module within a web press for inhibiting media deformation may include a fluid deposition device located on a side of a media, and a processing device to control the fluid deposition device to selectively apply a wetting agent to the media. The deposition of the wetting agent may be based on the location of content printed on the media as defined by print data.

Abstract: An example of an apparatus including a front-end engine to receive document data in a first format for printing via a network. The apparatus includes a conversion engine in communication with the front-end engine. The conversion engine is to carry out a conversion of the document data from the first format to an uncompressed format, wherein the conversion engine generates metrics associated with the conversion. The conversion engine parses the document data in the uncompressed format into a plurality of separations. The apparatus includes a compression engine to process a separation of the plurality of separations from the uncompressed format to a second format, wherein the second format is a predetermined format associated with a printing device. The apparatus includes a print engine controller to transmit the separations in the second format to the printing device, wherein the print engine controller uses the metrics to predict a starvation condition.

Abstract: In one example in accordance with the present disclosure, a remote printer control device is described. The remote printer control device includes a power supply and a power interface. The power interface provides power from the power supply to the printer when an operational power supply for the printer is disengaged. A controller of the remote printer control device interfaces with, and controls, the printer when the operational power supply for the printer is disengaged.

Abstract: In an example, a system is described that includes a plurality of nozzles, a vision system, a controller, and a fluid ejection array controller. The plurality of nozzles ejects fluid that creates an output. The vision system detects a visual discontinuity in the output. The vision system further identifies a faulty nozzle that is the source of the visual discontinuity. The controller selects an alternate nozzle to eject fluid in place of the faulty nozzle to minimize the visual discontinuity. The controller may also select a time at which the faulty nozzle ceases ejecting fluid and the alternate nozzle commences ejecting fluid in place of the faulty nozzle to minimize the visual discontinuity. The fluid ejection array controller controls ejection of fluid by the faulty nozzle and the alternate nozzle under instructions from the controller.
