Method for determining a per-image resource consumption in a printer

A printer comprising a print job controller and a print engine, wherein the print job controller is configured to compile a print job that comprises at least two images to be printed, the print job controller comprising an estimation section arranged to estimate a respective amount of resource consumption for each of the at least two images on the basis of print data that define the images, wherein the printer comprises a resource consumption measuring system, and the print job controller is configured to perform a method comprising the steps of:

• a) compiling a print job with at least two images;
• b) printing at least a part of each of the at least two images while monitoring a total amount of resource consumption;
• c) estimating the amount of resource consumption for the printed part of each of the at least two images on the basis of the print data;
• and
• d) proportioning the monitored total amount in proportion to the estimated amounts.

A computer program product embodied on a non-transitory computer-readable medium, comprising program code which, when executed on a print job controller of a printer, the printer comprising a resource consumption measuring system, causes the print job controller to perform the steps of:

• a) compiling a print job with at least two images;
• b) printing at least a part of each of the at least two images while monitoring a total amount of resource consumption;
• c) estimating the amount of resource consumption for the printed part of each of the at least two images on the basis of print data that define the images;
• and
• d) proportioning the monitored total amount in proportion to the estimated amounts.
