Python is deprecating os.system in favour of using the subprocess
package.

	subprocess.call('lp some_options file.pdf', shell=True)

or

	subprocess.call(['lp', *some_options, 'file.pdf')

assuming some_options is a sequence of strings, on option per string.

Debian Sid has packages python-cups and python-cupshelpers which are
Python 2 APIs for working with CUPS. Sadly there do not seem to be
Python 3 versions of these In Debian, but the package in PyPI is pycups
so can be made available to Pytho 3. Also:

I have not used these yet myself, but I have trying them out on my
agenda for later in the spring.
