Abstract: An apparatus is disclosed that automatically generates a set of recommended printer settings 300 for a print job 100 submitted to a printer 10. The apparatus comprises at least one processor which executes computer program code from at least one memory, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to: receive a submitted print job for a printer, the submitted print job including content to be printed by the printer and a set of user input printer settings for the printer; analyze the content to be printed by the printer; designate a classification for the submitted print job based on said analysis; obtain historical data from a knowledge database, the historical data being related to prior print jobs run on the printer and indicating printer settings used when running the prior print jobs on the printer; and output a set of recommended printer settings based at least in part on one or more of the received print job, the designated classification and the obtained historical data.

Abstract: A method of inkjet printer operation produces a security pattern in a printed document. In one embodiment, the security feature is printed in the document as a line target with printheads that have been rotated so the rows of inkjets in the printhead are not aligned in the cross-process direction. The line target in the original document has a frequency response to that differs from a copy formed with a device that does not have rotated printheads. In another embodiment, a sneeze pattern is modified by shifting pixels of at least one color separation in the sneeze pattern in a cross-process direction or a process direction. A copy is identified because it does not contain the shifted pixels.
