Abstract
According to a method herein, a number of pixels marked and times of printing are automatically determined for a plurality of images. A time-based moving window of pixel counts for a subset of the plurality of images being contiguously processed in a current time window is automatically calculated, based on the number of pixels marked and the times of printing of the subset of the plurality of images processed in the current time window. Marking material usage to print the plurality of images for the current time window is automatically determined, based on the time-based moving window of pixel counts of the current time window. The method automatically determines if the marking material usage for the current time window exceeds a threshold. A notification is automatically output if the marking material usage for the current time window exceeds the threshold.
