I have a WORKING batch file that I want to execute by my Python program. here is the portion of program related to that task:

def execute_batch_file(self): batch_file_path = r'C:UsersUTENTEDesktopProgrammi compilati PythonOP10prova.bat' subprocess.Popen(batch_file_path, shell=True)

when I run the program I get the error message “Cannot open exaple.prn for reading”.
Again, if I execute the batch file manually I have no issue whatsoever. It does work fine. When I run it by my program I get the message above.
For info, the batch file lunches an “lpr” command for a “.prn” file to be printed.

Any clue about the issue?

Thanks alot.
