Unable to initialize device PRN in Python

Question

I attempt to run a python program and the following pops up in command prompt:

\"Unable to initialize device PRN\"

I should also mention that the program runs fi

Answer 1

In my case restarting (close / open new) the console or the Command Prompt window works

Answer 2

Try changing name of the program; that worked for me. Don't forget: use fresh cmd when you start executing.

Answer 3

First of all install latest version of Python from it's official website (i.e. python.org/download) after that if you try to run it through command prompt instead of writing python3 just write python. After that >> it will appear then start writing your actual code. Make sure you re-run the command prompt window.

Answer 4

I know this is an old question, but I experienced this issue in VS Code after installing the latest version of Python and the Python extension.

To fix it, I just needed to add the Python installation path to my PATH environment variable.

• On Windows 10, go to Settings and search for Environment
• Click on Edit environment variables for your account
• Select Path and click the Edit button
• If the path to your Python.exe is not listed, click the New button
• Enter the path to your Python.exe application and click the OK button
  • The path for me was %LocalAppData%\Programs\Python\Python37-32\
• Restart VS Code and try to run your python script again

Answer 5

I had this same problem when I accidentally typed "print program.py" instead of "python program.py". The error message comes from the Windows command-line program named print. Those who suggested restarting the command prompt probably committed the same typo without noticing, and corrected it in their new command prompt.
