1. A system for determining an accurate amount of consumable in a print cartridge, the system comprising:
- a printing device having a print cartridge loaded therein, wherein the print cartridge has a cartridge identification associated therewith, wherein the print cartridge has an expected print yield that is different than an expected print yield of a standard yield cartridge manufactured for use in the printing device;
a processor; and
a peripheral device located external to the printing device and communicatively connected between the printing device and the processor to monitor communication between the processor and the printing device, wherein the peripheral device determines an accurate amount of remaining consumable by monitoring the communication between the processor and the printing device.

Abstract
Electronic systems, such as printing systems, often use components that have integral memory. The integral memory can be used to store information about the component. In some printing systems this memory includes a portion that stores a value indicative of a print yield. Disclosed is a method and system for allowing the memory to have data indicative of an increased print yield.

15. A method for determining an accurate amount of consumable in a print cartridge, wherein the print cartridge has a cartridge identification associated therewith and the print cartridge has an expected print yield that is different than an expected print yield of a standard yield cartridge manufactured for use in the printing device, the method comprising:
-
determining that a print cartridge installed in a printing device has a cartridge identification associated therewith; determining one more characteristics of the print cartridge based upon the cartridge identification; monitoring communication between a processor and the printing device to determine that the printing device has printed images, wherein the processor is located external to the printing device; determining an amount of consumable used to print the images; and determining an accurate amount of remaining consumable based upon the amount of consumable used to print the images and the cartridge identification.

16. A system for determining an accurate amount of consumable in a print cartridge, the system comprising:
-
a printing device having a print cartridge loaded therein, wherein the print cartridge has a cartridge identification associated therewith; a processor; and a peripheral device communicatively connected between the printing device and the processor to monitor communication between the processor and the printing device, wherein the peripheral device determines an accurate amount of remaining consumable by monitoring the communication between the processor and the printing device independent of an amount of remaining consumable determined by the printer. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 25, 26, 27, 28, 29)

30. A system for managing a printer, the system comprising:
-
a printing device having a print cartridge loaded therein, wherein the print cartridge has a cartridge identification associated therewith; a processor; and a peripheral device communicatively connected between the printing device and the processor to monitor communication between the processor and the printing device, wherein the peripheral device determines characteristics of the printing device or the print cartridge based upon the cartridge identification and the peripheral device communicates information to a user that is different than information that the printer communicates to the user. - View Dependent Claims (31, 32, 33, 34, 35)
