A method for determining a marking material usage estimate for a print job to be performed by a printing system is provided. The method is implemented in a computer system having one or more processors configured to execute one or more computer program modules. The method includes receiving compressed data of an image of the print job, wherein the image has a plurality of image pixels each having an image pixel intensity value, wherein the image pixels are transformed into the compressed data using a compression scheme; obtaining marking material usage statistics by partially decompressing the compressed data so as to obtain average pixel intensity values of the image pixels in the image; and determining the marking material usage estimate for the print job using the obtained marking material usage statistics. |
