打印机的主要技术指标有打印分辨率和打印速度,现在分别介绍如下:1、打印分辨率打印机分辨率采用DPI(Dot PerInch)表示,即指在一英寸宽度上可打印多少个点。点数越多,DPI的数值也越大,表示打印效果越好。一般来说,针式打印机分辨率最低,即使采用多次打印的倍密度技术打印(所谓倍密度是增加打印次数,使打印的点数增加,如双倍密度表示打印两次,第二次打印是在上一行的位置上稍稍移位),它的分辨率只能在360DPI以下。喷墨打印机的分 The printer’s main technical indicators are print resolution and print speed, are now introduced as follows: 1, print resolution Printer resolution using DPI (Dot PerInch) that is, how many dots can be printed in one inch width. The more points, the larger the DPI value, indicating that the better the printing effect. In general, stylus printers have the lowest resolution, even with multiple-fold multiplication technology (the so-called double density is to increase the number of printing, so that the print points increase, such as the double density that print twice, the second print is A little bit shifted in the position of the previous line), its resolution can only be below 360DPI.
