Abstract
A supply source indicator indicates whether an ink cartridge is received from a subscriber source. An ink order identifier indicates a combination of ink colors for different chambers in a color pen of a printer. When print data is received, the supply source indicator and the ink order identifier are accessed to determine whether the ink cartridge is received from a subscriber source.
Claims19
A method of controlling a print system, the method comprising:
- obtaining print data;
- accessing a supply source indicator from storage in an ink cartridge, wherein the supply source indicator identifies a source of the ink cartridge;
- accessing an ink order identifier from storage in the ink cartridge, wherein the ink order identifier indicates an order in which ink colors are provided in chambers of a color pen of the ink cartridge;
- determining whether the ink cartridge corresponds to a subscribed source based on the supply source indicator and the ink order identifier;
- and
- in the event that the ink cartridge is determined as corresponding to a subscribed source, causing the print data to be printed using the color pen, wherein the ink order identifier corresponds to the order of the ink colors provided when using the color pen.
A machine-readable storage medium encoded with instructions executable by a processor of a printer, the machine-readable storage medium comprising:
- instructions for receiving print data,
- instructions for accessing a supply source indicator bit from color pen identification bits in an ink cartridge, wherein the supply source indicator bit identifies whether the ink cartridge is provided from a subscribed source,
- instructions for accessing ink order identifier bits from the color pen identification bits, wherein the ink order identifier bits indicate an order of ink colors provided in chambers of a color pen of the ink cartridge,
- instructions for determining that the ink cartridge is not received from a subscribed source based on the supply source indicator bit and the ink order identifier bits, and
- instructions for generating an error message that indicates that the ink cartridge is not received from a subscribed source.
A printer comprising:
- a color pen comprising ink chambers, wherein each ink chamber corresponds to an ink color;
- storage comprising a supply source indicator and ink order identifier, wherein the supply source indicator indicates whether an ink cartridge is received from a subscribed source, and the ink order identifier indicates an order in which ink colors are provided in the ink chambers of the color pen;
- and
- a processor to:
- obtain print data,
- determine whether the ink cartridge corresponds to a subscribed source based on the supply source indicator and the ink order identifier, and
- in the event that the ink cartridge does not correspond to a subscribed source, identify the ink cartridge as being not received from a subscribed source.
An ink cartridge comprising:
- a color pen including a plurality of ink chambers, wherein each ink chamber corresponds to an ink color;
- and
- storage that stores a supply source indicator and an ink order identifier, wherein the supply source indicator indicates whether an ink cartridge is from a subscribed source, and the ink order identifier indicates an order in which ink colors are provided in the ink chambers of the color pen.
