I used CMD command like this ""Print /D:LPT1 D:\Data.txt" to finish my printing line by line. but I found this method has some limitation of DOS. e.g. When I want to print the character which DOS is not supported, then I need to install the Language package or some other software in dos envirnment. I wonder whether there is an activeX control which can solve my problem in windows mode not dos mode, so I can easy print the character which the operation system support.
Or maybe there is an other way to solve the problem of printing line by line.
Thanks in advance.
