There are several executables in system-config-printer that contain the shebang line: #!/usr/bin/env python
However, this makes it difficult to install alternative versions of Python on the system. If a user wishes e.g. to install python 3 on the system, and have a /usr/local/python in her PATH, this will break these executables.
These system executables are expecting to use the system python, and thus should use: #! /usr/bin/python
