Abstract
A method for determining the amount of toner required to render a print job using a print engine at a printing location without prior information about the toner level thereof, comprising the steps of accumulating in a first register the toner values of all the pixels in a rasterized image prior to sending the print job to the printing location; decrementing the toner level register for the print engine at the printing location if the accumulated value is less than or equal to the toner level of the print engine; and sending the print job to the print engine at the printing location for rendering.
