NOTE: settings.py update:

  Will need to include a section as follows to ini file:

[bcprinter]
printer1_host=<ip_address>
printer1_port=9100
printer2_host=<ip_address>
printer2_port=9100

Added a simple way to print out a label on inventory item summary
page. Needs major improvement on this page, but went for getting
labels printed to start with.
