Thank you. Can you elaborate? for instance, to send file path as argument?

Solution 2

this is how I'd do it in C#

Process p = new Process();
p.StartInfo.FileName = "print";
p.StartInfo.Arguments = @"/D:COM3 c:\myFile.txt";
p.Start();

Thanks a lot. But still i have a problem
I am using laptop connected to printer via USB,
Following vb code is not working.
Dim p As New Process
p.StartInfo.FileName = "Print.exe"
p.StartInfo.Arguments = "/D:USB001 C: rash.txt"
p.Start()
I believe its not working because its USB port. Does it mean the above will work only with COM port or LPT?(by the way, when the code is run, print window flashes On and is immediately closes, but it doesnot Print.)
Thanks in advance.

I don't think the above will work as DOS doesn't know about USB ports - only serial and parallel I'm afraid. So you could do one of three things:
1) Emulate a network printer - see here:
http://geekswithblogs.net/dtotzke/articles/26204.aspx[^]
2) Download DOSPRN shareware - see here:

3) If you at all possible don't write directly to the printer but use more up-to-date technology!

Hope this helps.
