Suggestion 1 :- There is a function available in
C++ that allows you to spawn processes.
Have a look at that function to launch .exes'.
I am sorry I cannot I remember the name of the function
but if you search for spawning processes in your IDE
you may be able to find it.
I have tried it and it works fine.
You can observe the processes being spawned in the task manager
if you have NT although not in Java.
The advantage of Spawning processes is that your JSP will
continue to execute while the Printer excutes in a separate
thread.
Suggestion 2 :- To Run the printer perhaps you should consider
calling the Printer Driver directly which normally comes in the form
of a C/C++ DLL.
Perhaps you should also consider combining
java.lang.Runtime.exe() with the Thread class
hence taking advantage of processes running
in separate threads there by again releasing your JSP
to continue its path of execution of code unless you want to wait
for the printer to execute. However as you do not really have
any control over success or failure perhaps you should consider threads.
