Abstract
In summary, the present invention provides a method, apparatus and program product for calculating an estimate of the amount of toner coverage required for printing print data defined in a compressed data stream. The estimate is obtained with reduced processing by obtaining coverage data from a partially decompressed formed of the data stream and using this to obtain the coverage estimate, thus removing the need to do a full de-compression of the data stream. For example the coverage data is a count of toned pixels for at least one intensity level.
