Abstract
An inkjet printhead assembly includes at least one inkjet printhead including N primitives and an address having M possible address values. Each primitive includes a group of at most M drop generators. The address is cycled through all M address values to control a sequence of which one drop generator in the primitive is fired at a given time. One drop generator in the primitive can be fired simultaneously with one drop generator in each of the other primitives. A primitive to address ratio (N/M) of the printhead is at least 10 to 1.

An inkjet printhead comprising:
- an address having M possible address values;
- and
- N primitives, each primitive including:
- a group of at most M drop generators, wherein the address is cycled through all M address values to control a sequence of which one drop generator in the primitive is fired at a given time, wherein one drop generator in the primitive can be fired simultaneously with one drop generator in each of the other primitives, wherein a primitive to address ratio (N/M) of the printhead is at least 10 to 1.
An inkjet printhead assembly comprising:
- at least one printhead, each printhead including:
- an address having M possible address values;
- and
- N primitives, each primitive including:
- a group of at most M drop generators, wherein the address is cycled through all M address values to control a sequence of which one drop generator in the primitive is fired at a given time, wherein one drop generator in the primitive can be fired simultaneously with one drop generator in each of the other primitives, wherein a primitive to address ratio (N/M) of the printhead is at least 10 to 1.
An inkjet printing system comprising:
- at least one printhead, each printhead including:
- an address having M possible address values;
- and
- N primitives, each primitive including:
- a group of at most M drop generators, wherein the address is cycled through all M address values to control a sequence of which one drop generator in the primitive is fired at a given time, wherein one drop generator in the primitive can be fired simultaneously with one drop generator in each of the other primitives, wherein a primitive to address ratio (N/M) of the printhead is at least 10 to 1.
A method of inkjet printing in an inkjet printhead comprising:
- providing an address having M possible address values;
- and
- printing ink drops from N primitives, wherein each primitive includes a group of at most M drop generators, wherein the printing of ink drops within each primitive includes cycling through all M address values of the address to control a sequence of which one drop generator in the primitive is fired at a given time, wherein one drop generator in the primitive can be fired simultaneously with one drop generator in each of the other primitives, wherein a primitive to address ratio (N/M) of the printhead is at least 10 to 1.
