摘要： A printer system comprises a communication interface and printer components. The communication interface receives a humidity value from a toner cartridge. The printer components control printing operation based on the humidity value. To control printing operation, the printer components may configure a dither matrix based on the humidity value. The toner cartridge comprises a humidity sensor and a communication interface. The humidity sensor detects a humidity level and generates the humidity value to correspond to the humidity level. The communication interface transfers the humidity value from the humidity sensor to the printer system.

摘要： The method of the invention converts colors resident in a first device color space to gray levels for reproduction by a single color marking media in a color or monochrome rendering device. The method converts a set of red, green and blue (RGB) primary color values received from a processor to gray level values. The method applies a gamma correction function to the RGB primary color values and further scales the values to a range of from 0 to 1. The method then converts the gamma-corrected and scaled RGB primary color values to a Y luminance value (in the XYZ tristimulus color space) through use of the expression: Y=YR(R)+(YG−kG)(G)+(YB+kB)(B) where: YR, YG, and YB are coefficients that provide a luminance value in the XYZ color space in accordance with accepted observer standards; kG is a correction value that renders the green component darker; and kB is a correction value that renders lighter the blue component. The resulting luminance value is then converted to a device gray value and stored in a table for later use.

摘要： Methods of providing lower resolution format data into higher resolution format are described. A laser printing system is provided having first and second lasers configured to receive and be driven by raster data. Image data, which is to be rendered onto a print medium is received in a first resolution format. The first resolution format is converted into a second resolution format which is greater than the first resolution format by mapping the image data to provide mapped image raster data in the second resolution format. The first laser is driven with a portion of the mapped image raster data, and the second laser is driven with another portion of the mapped image raster data.

摘要： Methods of providing lower resolution format data into higher resolution format are described. In one embodiment a first predetermined amount of image data is provided which is to be rendered onto a print medium. The first predetermined amount of image data is provided in a first resolution format. Using the first predetermined amount of image data, the first predetermined amount of image data is replicated into multiple predetermined amounts of data sufficient to provide said first predetermined amount of image data into a second resolution format which is greater than the first resolution format. At least one laser beam in a laser printer system is modulated using the multiple predetermined amounts of data.
