摘要： A printing system that dynamically adjusts the resolution at which printing will occur based on the lightness or darkness of the medium upon which the image will be printed is provided. The reflectivity of the medium upon which an image is to be printed is determined, and hence the relative lightness or darkness of the medium. The resolution at which the image will be printed is adjusted based on the determined reflectivity of the medium. For lighter colored mediums, sufficient contrast between the printed image and the medium upon which the image is printed can be maintained utilizing a lower resolution, while a higher resolution must be utilized to maintain sufficient contrast for darker colored mediums. Since it is not necessary to utilize the higher resolution for all mediums to ensure sufficient contrast is always provided, the amount of ink used by the printing system is reduced.
摘要翻译：提供一种基于印刷图像的介质的亮度或暗度来动态地调整打印发生的分辨率的打印系统。确定要打印图像的介质的反射率，因此确定介质的相对亮度或暗度。基于确定的介质的反射率来调整图像将被打印的分辨率。对于较浅的彩色介质，可以利用较低的分辨率来保持印刷图像和印刷图像的介质之间的足够的对比度，同时必须采用更高的分辨率以保持较深色介质的足够的对比度。由于不需要对所有介质使用较高分辨率来确保始终提供足够的对比度，所以打印系统使用的墨水量减少。

摘要： Systems and methods for providing evidence of printing in metering systems even in the event of a print head failure are provided. Along with generating a primary image for an indicium that evidences payment, a secondary image for the indicium, identical to a corresponding portion of the primary image but at a lower density, with physical boundaries that are within the boundaries of the primary image, is also generated. The primary image is printed by a first nozzle array, and the secondary image is printed by a second nozzle array. Because the primary image completely overlaps the secondary image, the secondary image is undetectable if the primary image is properly printed. The secondary image provides evidence of printing of the indicium that can be used to obtain a refund for the indicium in the event that the primary image was not printed due to failure of the first nozzle array.
摘要翻译：提供了即使在打印头故障的情况下也能在计量系统中提供印刷证据的系统和方法。除了产生证据支付的标记的主图像之外，与主图像的对应部分相同但是具有较低密度的标记的二次图像与主图像的边界内的物理边界也是生成。主图像由第一喷嘴阵列打印，次要图像由第二喷嘴阵列打印。由于主图像完全与次要图像重叠，如果正确打印了主图像，则辅助图像将不可检测。次要图像提供印刷标记的证据，可以用于在由于第一喷嘴阵列的故障而未打印主图像的情况下获得标记的退款。

摘要： A high speed mail processing system having multiple printing modules is provided with a single printer controller or portion thereof that is used to control the operation of all of the printing modules. Messages that originate from the control unit of the mail processing system include a header that identifies the intended recipient(s) of the message, and the single printer controller can route the message to the intended recipient(s) based upon the identification included in the header. The printer controller can be separated into different parts for performing different functions related to the printing modules and only a single part of the printer controller can be provided to control respective functions for all of the printing modules in the system. By allowing the multiple printing modules to share a controller, the need for duplicated hardware is software is removed, thereby decreasing both the complexity and cost of the system.

摘要： Methods and systems that can detect low ink levels in an ink supply and that allows replacement of the ink supply without having to stop the printing operations. A printing system is provide with a sub-tank from which the print head receives ink. A removable ink tank supplies ink to the sub-tank. The removable ink tank is provided with a memory device to store information associated with the ink tank. A sensor is provided in the sub-tank from which the amount of ink in the sub-tank can be determined. The system reads the memory device on the ink tank and monitors the sensor in the sub-tank to determine operating conditions for the system. The ink tank can be replaced without having to stop the printing process.

摘要： Methods and systems for using ink-jet technology for high speed printing are provided. Print growth between pixels in an image is significantly reduced or eliminated by adjusting the printing of the pixels based on the status of the following pixel to be printed, i.e., whether the following pixel is either black or white. If a black pixel, formed by a plurality of columns of dots, is being followed by a white pixel, the column of dots closest to the white pixel will not be printed, and the column of dots in the black pixel next to the column of dots closest to the white pixel are staggered such that the pixel appears filled despite the absence of the column of dots closest to the white pixel and will still be properly read as a black pixel by a scanner reading the image.
摘要翻译：提供了使用喷墨技术进行高速打印的方法和系统。基于要打印的以下像素的状态，即随后的像素是黑色还是白色，通过调整像素的打印来显着减少或消除图像中的像素之间的印刷增长。如果由多个点列形成的黑色像素之后是白色像素，则不会打印最靠近白色像素的点的列，并且在该列的旁边的黑色像素中的点列最接近白色像素的点交错，使得即使不存在最靠近白色像素的点的列，也可以通过读取图像的扫描仪将它们适当地读为黑色像素，因此像素出现填充。
