SELECTING PROTOCOL CODES
Protocol codes are the special control characters that prepare the printer to receive instructions. For example, the
<ESC> character tells the printer that a command code will follow and the <ENQ> character asks for the printer
status.
There are two pre-defined different sets of Protocol Control codes to choose from. Each set is made up of six
special characters. The Standard Protocol Control codes are non-printable characters, and the Non-Standard
Protocol Control codes are printable characters. The Non-Standard set may be useful on host computers using
protocol converters or in an application where non-printable ASCII characters cannot be sent from the host.
This manual uses the Standard Protocol Control codes for all of the
examples. Alternately, the user may define and download a set of custom
Protocol Control Codes (see Appendix D).
