Abstract
Selecting nozzles can include selecting nozzles of a plurality of nozzles to print a portion of a print job based on content of the print job and assigning firing reservations to the selected nozzles, where a total number of the firing reservations assigned to the selected nozzles is comparatively less than a total number of the plurality of nozzles.
Claims20
A method comprising:
- in a controller of a printer, analyzing content of a print job sent to the printer, wherein the printer comprises a print bar to span the width of a print substrate, and the print bar comprises a printhead having a plurality of nozzles arranged in a primitive;
- the controller selecting a first set of nozzles of the plurality of nozzles to print a portion of the print job on the print substrate based on the content of the print job;
- the controller assigning firing reservations to the selected first set of nozzles, wherein a total number of the firing reservations assigned to the selected first set of nozzles is comparatively less than a total number of the plurality of nozzles;
- the controller sending firing data only to the selected first set of nozzles to reduce an amount of firing data sent to the plurality of nozzles;
- the controller firing the selected first set of nozzles based on the firing data to print a portion of the print job on the print substrate;
- and
- the controller reassigning at least some of the firing reservations to a second set of addresses associated with a selected second set of nozzles of the plurality of nozzles.

- fire the selected first set of nozzles based on the firing data to print a portion of the print job on the print substrate;
- and
- reassign at least some of the firing reservations to a second set of addresses associated with a selected second set of nozzles of the plurality of nozzles.
