A printer which provides detailed information on usage of consumables such as paper, ink, toner, etc., aiding in planning print tasks and ordering supplies. The printer also provides information on printer setting usage and print costs.
Claims18
A method of reporting print costs for a printer, the method comprising:
- updating print cost information in said printer, said updating comprising executing code with a processor to:
- collect data by said printer on consumable usage, said consumable usage data including quantity of at least one coloring agent used;
- transmit said data to an external entity for analysis;
- and
- store updated print cost information from said external entity in a memory, wherein said updated print cost information is based at least partly on said data;
- said method further comprising:
- receiving a request for said print cost information;
- reading said print cost information from a said memory;
- and
- outputting said print cost information.

A printer, comprising:
- at least one metering device for dispensing consumables in said printer, said at least one metering device counting a number of dots printed per page for a given color;
- and
- at least one accounting device connected to said at least one metering device for tracking usage of said consumables and for calculating print costs, said at least one accounting device calculating a volume of a given coloring agent used per page based on said number of dots and calculating said print costs at least in part based on said volume and a price for a unit of said coloring agent.
A method of providing printer information, the method comprising:
- tracking print media usage in a printer;
- executing code with a processor to calculate statistics based at least partly on said print media usage, said statistics comprising at least one member selected from the group consisting of frequency of usage by print media size, frequency of usage by print media type, an amount of consumed print media for a given time period, a cost of consumed print media for a given time period, how long a given amount of a print media type will last;
- and outputting said statistics.
A method of providing printer information, comprising:
- tracking consumable usage in a printer, said consumable usage comprising at least one member selected from the group consisting of amount of a coloring agent used per page overall, amount of a coloring agent used per job, amount of a coloring agent used per page in a given print quality setting, number of pages per job, number of pages per job in a given print quality setting, average amount of all types of print media consumed in a given time period, amount of print media of a given type consumed in a given time period, frequency of usage of a given print quality setting, and average life of a unit of a coloring agent;
- analyzing by said printer said consumable usage to determine print costs, said print costs comprising at least one member selected from the group consisting of an average cost per page for a given print quality setting, average cost of print media consumption for a given time period, average cost per job, average cost per page per job, and average printing cost for a given time period;
- and
- said printer reporting said consumable usage and print costs.
