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 indicates a need for printhead purging without requiring analysis of printed images to detect streakiness in the images. The method compares terms of a histogram of a filtered response of an inkjet status vector to a streakiness metric to determine whether the distribution of inoperative inkjets in a printhead enables missing ink techniques to be used to compensate for inoperative inkjets in the printhead.

Abstract: A system and method of providing annotated trajectories by receiving image frames from a video camera and determining a location based on the image frames from the video camera. The system and method can further include the steps of determining that the location is associated with a preexisting annotation and displaying the preexisting annotation. Additionally or alternatively, the system and method can further include the steps of generating a new annotation automatically or based on a user input and associating the new annotation with the current location.
