Abstract

Examples disclosed herein relate to receiving a usage report from a printer, wherein the usage report comprises a count of pages printed and a time spent in a first power state; calculating a power consumption for the printer according to the usage report, and providing a report of historic power consumption.

First claim

What is claimed is:

1. A non-transitory machine readable medium storing instructions executable by a processor to:
receive a usage report from a printer, wherein the usage report comprises a count of pages printed, a time spent in each of a plurality of power states, and a runtime for a printer component of the printer;
calculate a power consumption for the printer based on the count of pages printed, the time spent in each of the plurality of power states included in the usage report, and the runtime for the printer component; and
provide a report of historic power consumption.

2. The non-transitory machine readable medium of claim 1 , wherein the instructions to calculate the power consumption for the printer comprise instructions to multiply the count of pages printed by a watt-hours per page measurement.

3. The non-transitory machine readable medium of claim 1 , wherein the instructions to calculate the power consumption for the printer comprise instructions to calculate power consumed in at least one of the power states by multiplying a wattage drawn in the at least one power state by the time spent in the at least one power state.

4. The non-transitory machine readable medium of claim 3 , wherein the wattage drawn in the at least one power state is configurable based on a model of the printer.

5. The non-transitory machine readable medium of claim 1 , wherein the plurality of power states comprises: a ready state and a sleep state.

6. The non-transitory machine readable medium of claim 5 , wherein a printer component is active in a first power state and inactive in a second power state.

7. The apparatus of claim 1 , wherein the instructions to receive the usage report from the printer further comprise instructions to receive the usage report from a plurality of printers.

8. The apparatus of claim 7 , wherein the instructions to provide the report of historic power consumption further comprise instructions to provide the report of historic power consumption for the plurality of printers.

9. The apparatus of claim 1 , wherein the instructions to provide the report of historic power consumption further comprise instructions to provide a report of projected power consumption based on the calculated power consumption for the printer.

10. A method comprising:
receiving a usage report including usage data from each of a plurality of printers, wherein the usage data comprises a count of pages printed, a time spent in each of a plurality of power states, and a runtime for a printer component of the printer;
calculating an aggregate power consumption for the plurality of printers based on the count of pages printed, the time spent in each of the plurality of power states included in the usage data, and the runtime for the printer component; and
providing a power consumption report for the plurality of printers.

11. The method of claim 10 , wherein the power consumption report is based on an amount of power consumed by each of the plurality of printers in each of a plurality of operating states.

12. The method of claim 10 , wherein the power consumption report further comprises a projected power consumption based on the calculated aggregate power consumption for the plurality of printers.

13. The method of claim 10 , wherein calculating the aggregate power consumption comprises evaluating the time spent in each of the plurality of power states according to a configurable power usage figure for each of the plurality of power states.

14. A system, comprising:
a data collection engine to:
receive, from each of a plurality of printers, a usage report comprising a count of pages printed, a time spent in each of a plurality of power states, and a runtime for a printer component of the printer;

a calculation engine to:
calculate a power consumption based on the count of pages printed, the time spent in each of a plurality of power states, and the runtime for the printer component included in the usage report from each of the plurality of printers, wherein the power consumption is based on a power state power usage figure for each of the plurality of power states, a per-page power usage figure, and a component power usage figure for the printer component; and

a report engine to:
provide a power consumption report for each of the plurality of printers, wherein the power consumption report comprises a historic power consumption and a projected future power consumption.
