摘要:
A method for splitting a print image data plane for printing with multiple printheads includes replicating the print image data plane into a plurality of print image data planes corresponding to the multiple printheads, linearizing the plurality of print image data planes, and half-toning the plurality of print image data planes, the half-toning being configured to convert the plurality of print image data planes into a n-plane image with interlaced columns, wherein n corresponds to the multiple printheads.

An ink delivery system for a printer includes an ink reservoir, a printhead assembly, a pump configured to provide ink from the ink reservoir to the printhead assembly at a selected pressure, and a controller configured to adjust the selected pressure based on a characteristic of an image to be printed.

In one embodiment, a method for printing includes selecting a nozzle for printing a pixel, determining a time since the nozzle was last actuated, and, if the time since the nozzle was last actuated exceeds a threshold time, then, before actuating the nozzle to print the pixel, actuating the nozzle a number of actuations corresponding to the time since the nozzle was last actuated.
摘要:
A printer includes at least one controller having first mode configured to control printing of an image including a sequence of columns by controlling printing a first column in the sequence and a fourth column in the sequence with a first printhead, a second column in the sequence and a fifth column in the sequence with a second printhead, and a third column in the sequence and a sixth column in the sequence with a third printhead.
摘要:
A method of printing an image in a fixed head printer system includes sensing a medium speed of a medium traveling in proximity to a plurality of ink printheads. A maximum optical density of the printer system at the sensed medium speed is determined. The firing frequency of the plurality of ink printheads is adjusted in response to a change in medium speed such that the maximum optical density of the printer system at the sensed medium speed is not exceeded.
