Name This is the name assigned to each individual TCP3 unit. Normally each converter is given a
name which is easy to associate with the connected printer. Often this name is geographically inspired
for example a device attached to a Brother printer on the 3rd floor near column G7 might be named:
Brother3-G7.
Hostnames are composed of series of labels concatenated with dots, as are all domain names. For
example, "tcp3.local" is a hostname. Each label must be between 1 and 63 characters long, and the entire
hostname (including the delimiting dots) has a maximum of 255 characters.
The Internet standards RFC (Request for Comments) for protocols mandate that component hostname
labels may contain only the ASCII letters 'a' through 'z' (in a case insensitive manner), the digits '0' through
'9', and the hyphen ('-'). (RFC 1123) permitted hostname labels to start with digits. No other symbols, punc-
tuation characters, or white space are permitted. Please make sure a valid hostname is given, otherwise
