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.
