据有关统计资料显示,1999年中国打印机市场总销量达234.2万台,2000年中国打印机市场的销售总量将达282万台。而在如此众多的打印机中,你如何能选购一台令你满意的打印机呢?一般而言,在选购打印机时应注意三个方面的指标,首先是打印精度DPI(DotPerInch),所谓DPI是指打印机在每英寸可打印的点数,是衡量打印质量的一个重要标准,也是一个最为基本的判断打印机分辨率的指标。至少应有300dpi的分辨率,才能使打印效果得到基本保证。一般应用DPI值也不一定是越大越好,720dpi左右就比较合适了;其次是打印速度PPM(PagePerMinute),PPM是指打印机每分钟可打印多少页,是衡量打印机打印速度的一个重要指标。但要注意,打印机说明书上所标明的PPM值是指该机所能达到的最高打印速度,实际使用时,这个值会受到多种因素的影响,肯定会低于标称值;最后是打印幅面,普通打印机的打印幅面一般以A4的为主。
According to statistics, in 1999 China’s total printer market reached 2.342 million units in 2000, China’s total printer sales will reach 2.82 million units. In such a large number of printers, how can you buy a printer that you are satisfied with? In general, when buying a printer should pay attention to three indicators, the first is the print accuracy DPI (DotPerInch), the so-called DPI Refers to the printer can print points per inch, is an important measure of print quality, but also one of the most basic indicators to determine the resolution of the printer. At least 300dpi resolution, to print the basic guarantee. The general application of DPI value is not necessarily the bigger the better, 720dpi or so more appropriate; followed by the print speed PPM (PagePerMinute), PPM is how many pages the printer can print per minute, is a measure of the printer print speed is an important indicator. However, it should be noted that the PPM value indicated on the printer’s manual refers to the maximum print speed the machine can achieve. In actual use, this value will be affected by many factors and will certainly be lower than the nominal value. Finally, the print format , General printer print format generally A4-based.
