    • A method for adaptively matching print quality and performance in a host based printing system including a host computer connected to a printer via an interface. The method includes the steps of: determining a print process time corresponding to an amount of time for a page to print based on current printer settings of the printer; determining a quantity of data to be transferred from the host computer to the printer; determining a data transfer time corresponding to an amount of time required to transfer the quantity of data from the host computer to the printer via the interface; comparing the print process time to the data transfer time to determine an amount of time that can be used by the printer to improve print quality; and determining optimum printer settings for the printer based at least in part on the amount of time determined in the comparing step.
    • 一种用于在基于主机的打印系统中自适应地匹配打印质量和性能的方法,包括通过接口连接到打印机的主机。 该方法包括以下步骤:基于打印机的当前打印机设置确定与要打印的页面的时间量相对应的打印处理时间; 确定要从主机传输到打印机的数据量; 确定与通过所述接口将数据从所述主计算机传送到所述打印机所需的时间量相对应的数据传送时间; 将打印处理时间与数据传送时间进行比较,以确定打印机可以使用的改善打印质量的时间量; 以及至少部分地基于在所述比较步骤中确定的时间量来确定所述打印机的最佳打印机设置。

    • A method of performing interlace printing on a print medium with a printhead of an ink jet printer includes providing an array of pixel locations on the print medium. Each pixel location has a common maximum number M of ink drops that the pixel location may receive. Each pixel location is assigned a respective desired number D of ink drops which are to be placed at the pixel location. Each desired number D is less than or equal to M. Sets of threshold values are created. A number N of the sets of threshold values is equal to or greater than M. Each of the pixel locations corresponds to one of the threshold values of each set of threshold values. A respective, single ink drop is selectively jetted at each pixel location. Whether the single ink drop is jetted onto a respective pixel location is dependent upon the desired number D assigned to the respective pixel location and the corresponding threshold value of one of the sets of threshold values. The selectively jetting step is repeated N−1 additional times. Each selectively jetting step uses a different one of the sets of threshold values.
    • 使用喷墨打印机的打印头在打印介质上执行隔行打印的方法包括在打印介质上提供像素位置的阵列。 每个像素位置具有像素位置可以接收的墨滴的共同最大数量M。 为每个像素位置分配要放置在像素位置处的墨滴的相应期望数量D. 每个所需数量D小于或等于M.创建阈值的集合。 阈值集合中的N个等于或大于M.每个像素位置对应于每组阈值的阈值之一。 在每个像素位置选择性地喷射相应的单个墨滴。 单个墨滴是否喷射到相应的像素位置取决于分配给相应像素位置的期望数量D和阈值集合中的一组的对应阈值。 选择性喷射步骤重复N-1次。 每个选择性喷射步骤使用阈值集合中的不同的一组。
