description = [[
Retrieves configuration information from a Lexmark S300-S400 printer.

The Lexmark S302 responds to the NTPRequest version probe with its
configuration. The response decodes as mDNS, so the request was modified
to resemble an mDNS request as close as possible. However, the port
(9100/udp) is listed as something completely different (HBN3) in
documentation from Lexmark. See
http://www.lexmark.com/vgn/images/portal/Security%20Features%20of%20Lexmark%20MFPs%20v1_1.pdf.
