Intermec Standard Protocol
The Intermec Printer Standard Protocol is a half-duplex protocol.
All data transmissions to the printer consist of status inquiry
(ENQ), status dump (VT), or message blocks. Each message
block starts with the Start of Text (STX) character and ends with
the End of Text (ETX) character. Each message block must be
255 characters or less, including the STX and ETX characters.
The printer responds to each status inquiry or message block
with the printer status. The host should check the printer status
before downloading a message block to the printer. ENQ causes
the printer to transmit its highest priority status, while VT
instructs the printer to transmit all status that applies in the order
of their priority. The possible printer status, in descending
priority, is:
