True however "LexmarkI_6c:48:82" is enough of a clue as to 
the device type and each of the printers also talk TCP/IP. 
I hoped there is a means to cross reference for each printer's 
IP within a recorded capture.

When I enter 00:04:00:6c:48:82 into the Capture / Filter field.
The error displays: "Unable to parse filter string (parse error)."
