Abstract
It is determined whether a print job to be output on a color laser-printing device is to have reduced color toner usage. In response to determining that the print job is to have reduced color toner usage, the print job is adjusted so that the print job consumes less color toner when output on the color laser-printing device, by color-desaturating the print job.
Claims33
A method comprising:
- determining whether a print job to be output on a color laser-printing device is to have reduced color toner usage at least by comparing a color coverage of the print job to a threshold, the color coverage of the print job defined as a percentage of color toner on an average media sheet to result from printing the print job;
- and,
- in response to determining that the print job is to have reduced color toner usage, adjusting the print job so that the print job consumes less color toner when output on the color laser-printing device, by color-desaturating the print job,
- wherein determining whether the print job to be output on the color laser-printing device is to have reduced color toner usage comprises determining whether the color coverage of the print job is less than the threshold, such that the printer job is adjusted to have reduced color toner usage where the color coverage of the print job is less than the threshold.

A color laser-printing device comprising:
- a color laser-printing mechanism to output a print job;
- and,
- a mechanism to, in response to determining whether the print job to be output is to have reduced color toner usage, adjust the print job so that the print job consumes less color toner when output, by color-desaturating the print job,
- wherein one or more of
- the mechanism is to determine whether the print job to be output is to have reduced color toner usage at least by comparing a color coverage of the print job to a threshold, the color coverage of the print job defined as a percentage of color toner on an average media sheet to result from printing the print job;
- and,
- the mechanism is to determine whether the print job to be output is to have reduced color toner usage at least based on an amount of color toner a user generating the print job is allowed to use within a given time period, the given time period encompassing a plurality of print jobs of the user, and
- wherein the mechanism is to determine whether the print job to be output is to have reduced color toner usage by further determining whether the print job will utilize more color toner than a color toner amount remaining for the user, where the color toner amount is reset each time a predetermined time period has elapsed.

A color laser-printing device comprising:
- a color laser-printing mechanism to output a print job;
- and,
- means for determining that the print job to be output is to have reduced color toner usage, and for adjusting the print job so that the print job consumes less color toner when output, by color-desaturating the print job,
- wherein one or more of
- the means is to determine whether the print job to be output is to have reduced color toner usage at least by comparing a color coverage of the print job to a threshold, the color coverage of the print job defined as a percentage of color toner on an average media sheet to result from printing the print job;
- and,
- the means is to determined whether the print job to be output is to have reduced color toner usage at least based on an amount of color toner a user generating the print job is allowed to use within a given time period, the given time period encompassing a plurality of print jobs of the user, and
- wherein the means is to determine whether the print job to be output is to have reduced color toner usage by further:
- determining a color toner amount remaining for a user generating the print job:
- determining whether the print job will utilize more color toner than the color toner amount remaining for the user;
- and,
- in response to determining that the print job will utilize more color toner than the color toner amount remaining for the user, concluding that the print job is to have reduced color toner usage so that the color toner utilized by the print job does not exceed the color toner amount remaining for the user.
