A printing method includes obtaining an initial printer profile corresponding to a printing system having a plurality of ink colors, identifying a remaining ink parameter corresponding to each of the ink colors, and determining whether the remaining ink parameter of each of the ink colors are approximately equal to each other such that: performing a print job using the initial printer profile when the remaining ink parameter determination is that the remaining ink parameter of each of the ink colors are approximately equal to each other, and determining a modified printer profile by selectively changing color saturation for one or more of the ink colors to balance ink usage and performing the print job using the modified printer profile when the remaining ink parameter determination is that the remaining ink parameter of each of the ink colors are not approximately equal to each other.

A system and method for printing on media includes a printhead assembly, a memory, and a controller. The printhead assembly is configured to make physical print sweeps relative to print regions of the media and to print within the print regions during the physical print sweeps. The memory communicates with the printhead assembly and is configured to receive data associated with a logical print sweep. The data associated with the logical print sweep controls printing within a first print region of the media during a corresponding first physical print sweep. The controller communicates with the printhead assembly and memory. The controller initiates the first physical print sweep of the printhead assembly before all of the data associated with the logical print sweep is received by the memory.

In one embodiment a cartridge holder includes: a body having a plurality of bays therein for holding a cartridge and each bay having an electrical connector associated therewith for connecting to a chip; an adapter removably attachable to the body at a bay, the adapter having a site for a chip at a location where a chip installed at the chip site is connected to a connector in the bay when the adapter is attached to the body; and each bay configured to hold: without an adapter attached to the body at the bay, a first cartridge having a first shape and a chip thereon, and, with the adapter attached to the body at the bay, a second cartridge having a second shape different from the first shape and the second cartridge not having a chip thereon.
摘要:
A system and method are provided for intelligently selecting a print quality setting. Print quality selection logic automatically selects one of a plurality of print quality settings based on data relating to document content, prior print setting selections, user input and/or one or more characteristics of the current print request.

The described embodiments relate to methods and systems for forming die packages. In one exemplary embodiment, the method for forming die packages contacts interface areas of a die assembly to keep the interface areas free of an insulative material. The method distributes a flowable insulative material around portions of the die assembly.
摘要:
A test page produced by ink pens for calibrating drop weights for at least a first and a second printheads, comprising: a page with an area for color swatches; a plurality of color swatches disposed in the area; and a predetermined substantially uniform color background disposed in said area between and around said plurality of color swatches. In a system embodiment of the present invention, a sensor may be used for sensing spectral data for each color swatch in a plurality of color swatches; and a component may be provided for comparing the sensed spectral data for each color swatch in a plurality of the color swatches to spectral data for the background color and selecting one of the plurality of color swatches which has spectral data which is closest to the background color for use in adjusting ink volume for at least one of the ink pens.

The present invention includes as one embodiment a method for printing ink on a print media with a fluid ejection device of an inkjet printing mechanism, comprising generating first grid pattern data and second grid pattern data different from the first grid pattern data, sending the first grid pattern data to a first printing mechanism of the fluid ejection device and sending the second grid pattern data to a second printing mechanism of the fluid ejection device.
摘要:
An inkjet printing system and print routine for use in conjunction with the printing system. The print routine prepares rendered source print data having a data resolution into sets of sweep data used to control a printhead of a printer. Each sweep data set contains firing data for an individual sweep of the inkjet printhead at a resolution that is less than the final printed image resolution.
