Abstract
In one embodiment, an imaging device includes an ink density information gathering procedure. An ink use calculation procedure receives input from the ink density information gathering procedure, allowing the amount of ink used to be calculated. A job cost procedure calculates a print job value based on the amount of ink used.
Claims26
An imaging device, comprising:
- an ink density information gathering procedure;
- an ink use calculation procedure, to receive input from the ink density information gathering procedure, and to calculate ink used;
- and
- a job cost procedure, to calculate print job value, based on the ink used.
An imaging device, comprising:
- means for gathering ink density information;
- means for calculating ink use using the ink density information;
- and
- means for calculating print job value, based on the ink use.
A processor-readable medium comprising processor-executable instructions for deriving a cost for use in pay-per-use printing, the processor-executable instructions comprising instructions for:
- obtaining information about ink density of a print job;
- calculating ink used by the print job using the information;
- and
- assigning the print job a cost value, based on the ink used.
A method for calculating print job value, comprising:
- acquiring ink coverage information;
- determining ink used using the ink coverage information;
- pricing the print job value based on the ink used.
