推荐答案

如果您的打印机具有要安装的驱动程序，则可以使用普通的Windows打印系统.大多数打印机(包括POS打印机)都具有可用的Windows驱动程序. (无论如何，大多数点矩阵打印机都是与Epson兼容的.)某些POS打印机驱动程序也允许直接将转义码发送到打印机(使用特殊字体).可能您不需要这种功能.

如果不是这种情况，则可以在添加打印机向导"的帮助下添加通用/纯文本"打印机(驱动程序).完成后，您可以为其配置某些命令(转义序列)-字体大小10/12/17，粗体打开/关闭，下划线打开/关闭，作业开始/停止，进纸和尺寸选择.

If your printer has driver to install, then you can use normal Windows print system. Most printers, including POS ones, have working Windows drivers available. (Most dot-matrix printers are Epson compatible anyway.) Some POS printer drivers allow send escape codes directly to printer too (using special fonts); probably you don''t need such functionality.

If this is not the case, then you can add Generic/Text Only printer (driver) with help of Add Printer Wizard. Once done, you can configure certain commands (escape sequences) for it - Font size 10/12/17, Bold on/off, Underline on/off, job start/stop, paper feed and size select.
