Protocol, cont.
• Intermec Standard Protocol
The Intermec Printer Standard Protocol is a half-duplex pro-
tocol. 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 priorities are
