20090033701 | PRINTHEAD WITH MULTIPLE NOZZLES SHARING SINGLE NOZZLE DATA - An inkjet printhead for use in a printer so that it can print onto a substrate at different print resolutions. The inkjet printhead has an array of nozzles, each nozzle having an ejection aperture and a corresponding actuator for ejecting printing fluid through the ejection aperture. A print engine controller sends print data to the array of nozzles in accordance with a designated print job. During use, the print engine controller can selectively reduce the print resolution by apportioning print data for a single nozzle between at least two nozzles of the array. The invention recognizes that some print jobs do not require the printhead's best resolution—a lower resolution is completely adequate for the purposes of the document being printed. This is particularly true if the printhead is capable of very high resolutions, say greater than 1200 dpi. By selecting a lower resolution, the print engine controller (PEC) can treat two or more transversely adjacent (but not necessarily contiguous) nozzles as a single virtual nozzle in a printhead with less nozzles. The print data is then shared between the adjacent nozzles—dots required from the virtual nozzle are printed by each the actual nozzles in turn. This serves to extend the operational life of all the nozzles. | 02-05-2009 |
