摘要： A method and apparatus for determining an optimum print density for an ink jet printer (130) uses characteristics of a printer (130) and its peripheral components such as an ink jet printhead (120), and an ink supply unit (110) to reach an optimum print density. The ink jet printer (130) receives a print command from a computer (100). The printer (130) reads an ink drop volume parameter from a printhead memory device (121) on the ink jet printer (130). The processor (131) in the printer (130) determines an ink density compensation value for the ink jet printhead (120) based on the ink drop volume parameter. The processor (131) on the ink jet printer (130) applies the ink density compensation value to the print command, thereby creating a depleted print command. Finally, the depleted print command is printed.

摘要： A printing system that adjusts to drop volume characteristics of pens installed within an associated printer. Each pen (202, 204, 206) has a characteristic drop volume (208, 210, 212) representing the typical volume of ink expelled by the pen in forming ink drops used to form output pixels. Up to a maximum of N drops are used to form each pixel. A printer driver (100) receives print data for the printer indicating saturation values (FIG. 3) for pixel data to be printed. Based on an expected pen drop volume, each saturation value maps to a corresponding number of ink drops for that value. To reduce data volume sent to the printer, the range of zero to N drops is subdivided into levels (418, 420, 422, 424), each level representing some number of drops per pixel, and this level data is sent to the printer. If the characteristic drop volume of the pen is different from the expected volume, the subdivision of levels can be adjusted to compensate for differences in drop volumes. A related method includes the steps of defining at least first, second, and third levels of printing saturation, where in the first, second, and third level are respectively ejected N1, N2, and N3 droplets of ink per pixel. This method includes receiving data related to a characteristic drop volume associated with the printing system, and setting the value of at least one of {N1, N2, or N3} in accordance with the received data. The characteristic drop volume may be stored within a memory associated with each pen.

摘要： A passively-multiplexed resistor array has rows and columns of conductors. Resistors span the intersections of the conductors, and one or more selected resistors may be energized by energizing the corresponding row(s) and column(s). However, other, unselected, resistors may also be partially energized. By adding additional rows or columns of "minimizer" resistors, the maximum power in unselected resistors may be reduced. The minimizer resistors are electrically connected in the passively-multiplexed resistor array but do not perform the function of the other resistors in the array.

摘要： Method and system for increasing the effective resolution at which a lower resolution input pixel image is printed on a higher resolution dot matrix printer such an ink-jet or laser printer are disclosed. Illustratively, a 300-dpi by 300-dpi input pixel image is prepared at the printer for printing at 600-dpi by 600-dpi, with otherwise jagged edges appropriately smoothed to produce high print quality. Each pixel (E5) and its predefined neighboring pixels in the input image are compared to stored image templates and when a match is found, the corresponding quad pixel, or super-pixel (S), to be output is altered from a mere replication of the input pixel, thereby to eliminate jagged edges. Memory space in the printer is reduced by storing templates (T1...T82) that represent only a fraction of the problem patterns, the input pixel image being reoriented between comparisons in order to account for all possible cases. If it is determined that there are gray-scaled pixels within the neighborhood surrounding and including a given pixel (E5) of the input pixel image, the corresponding super-pixel (S) produced at the output for printing preserves the gray-scale of the original.
摘要翻译：公开了一种用于提高在较高分辨率点阵式打印机（诸如喷墨或激光打印机）上打印较低分辨率的输入像素图像的有效分辨率的方法和系统。说明性地，在打印机处准备300dpi×300dpi输入像素图像，以600dpi×600dpi打印，否则锯齿边缘被适当地平滑以产生高打印质量。将输入图像中的每个像素（E5）及其预定义的相邻像素与存储的图像模板进行比较，并且当发现匹配时，要输出的相应的四像素或超像素（S）从仅仅复制输入像素，从而消除锯齿状边缘。通过存储仅代表问题模式的一部分的模板（T1 ... T82）来减少打印机中的存储空间，输入像素图像在比较之间重新定向，以便考虑所有可能的情况。如果确定在邻近周围并包括输入像素图像的给定像素（E5）内的灰度像素，则用于打印的输出处产生的对应超像素（S）保留了灰度级原版的。
