推荐答案

您需要添加转义字符来完成您的工作.
像
Chr(27)+"E"表示
上的普通粗体 Chr(27)+"F"表示正常的粗体显示
Chr(27)+ Chr(14)for Double Soze大胆的脸
Chr(27)+ Chr(18)用于Double Soze粗体字消除
等

检查打印机文档或搜索Google以获取打印机转义字符.

You need to Add escape Chars to do your job.
Like
Chr(27) + "E" for Normal Bold face on
Chr(27) + "F" for Normal Bold face off
Chr(27) + Chr(14) for Double soze bold face
Chr(27) + Chr(18) for Double soze bold face off
etc.

Check printer documentation or Search Google for Printer escape Chars for more chars

要在没有打印驱动程序的情况下进行打印，您必须直接与并行端口通信，我不确定是否有相应的标准，或者您是否需要打印机的手册.

To print without a print driver, you''d have to communicate directly with the parallel port, I''m not sure if there''s a standard for that or if you''d need the manual for your printer.
