Abstract:
An ink delivery system for a printer (10) includes an ink reservoir (15), a printhead assembly (12), a pump (23) configured to provide ink from the ink reservoir to the printhead assembly at a selected pressure, and a controller (20) configured to adjust the selected pressure based on a characteristic of an image to be printed.
Abstract:
Embodiments for distributing print density are disclosed, comprising: a thermal management system (20) configured to create a density profile (402) associated with an image and configured to cause a print density of the image to be distributed over a plurality of printheads (24) according to the density profile (402).
Abstract:
A method of increasing data flow to a printing device (195) includes, with a first raster image processor (135), converting a document into a first bitmap having a first dot density and representing a black color plane of the document; with a second raster image processor (185), converting the document into a second bitmap at a second dot density that is a relatively lower dot density than that of the first bitmap, the second bitmap representing other color planes of the document; and transmitting data of the first and second bitmaps to a printing device (195) for printing to a print medium.
Abstract:
A printer (10) includes at least one controller (20, 26) having first mode configured to control printing of an image (36) 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 (24), a second column in the sequence and a fifth column in the sequence with a second printhead (24), and a third column in the sequence and a sixth column in the sequence with a third printhead (24).
