Abstract: Methods and systems herein provide for verification of a calibration of a printer utilizing a hand-held mobile device. In one embodiment, a mobile device includes a camera that captures image data of a calibration target printed by a printing system. The image data is captured in an uncontrolled environment. The mobile device further includes a processor that determines a difference between the uncontrolled environment where the image data was captured and a controlled environment, and adjusts the image data based on the difference. The mobile device then determines whether the printing system is out of calibration based on the adjusted image data.

Abstract: Methods and systems herein provide for estimating when the print quality of a printer is expected to decrease below a threshold based on a function of change in the print quality of the printer. In one embodiment, a system calculates a plurality of print quality measurements based on pages printed by a printer. The system determines a function of change of the print quality of the printer that is based on changes in the print quality measurements. The system estimates when the print quality of the printer is expected to decrease below a threshold based on the function of change in the print quality of the printer. The system then provides the estimate to a print operator.
