You need to escape the \ in your filename string. Either
p.StartInfo.FileName = @"G:\tst.prn";
or
p.StartInfo.FileName = "G:\\tst.prn";
If you still have a problem you could add an exit handler and check the ExitCode when it is called
p.Exited += new EventHandler(myProcess_exited);
In the handler check myProcess.ExitCode to get a start on what is happening.
(Of course, the obvious questions apply - does G:\tst.prn exist and is it accessible by the web server process, is there a default printer on this server)
You're telling the Windows Shell to "print" a prn file. Are you sure you have a "print" command of the shell associated to PRN files? If you don't, then nothing will happen there.
You also said that tried COPY command.... is there any printer installed in your server? Not sure if you realize that your code will try to print to a printer installed on the server where your asp.net website is hosted in.

You could refer the discussion about printing *.prn files using C#.net in MSDN forum(http://social.msdn.microsoft.com/Forums/en-US/winforms/thread/fe100d00-48e2-4ca1-97b7-86fb95fa63bc), hope it helps you,

As it is mentioned by Neodynamic, try using COPY
copy /b filename.prn lpt1
Also, take a look at this example, I think it might help.
