Writing looks even more straightforward:
>>> p = open('/dev/lp0', 'wb')
>>> p.write('VOOM!\r\n\f')
>>> p.flush()
>>> p.close()
This prints "VOOM!" on the top of the paper in the printer and ejects it.
I don't know how you would go about actually reading data from the
parallel port, though. The Linux printer driver, for example, doesn't
support it.
