Get a list of available printers
--------------------------------

To get a list of all printers, with details::

   $ lpstat -p

just the list of all available destinations on the local network::

   $ lpstat -e

the current default one::

   $ lpstat -d

Printing in greyscale
---------------------

To get the list of options available for your printer use::

   $ lpoptions [-p <printer_name>] -l

there will be a line like (note that different printers may have a more
specific option that you need to enable)::

   ColorModel/Print Color Mode: Gray *RGB

and then you'll have to add ``-o ColorModel=Gray`` to the ``lpr``
command line, e.g.::

   $ lpr -o ColorModel=Gray <filename>
