Some commands can contain both Parameter and Data elements, such as “print a
Code 39 symbol containing the data.”
SELECTING PROTOCOL CONTROL 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 different sets of Protocol Control codes to choose from on the printer.
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.
The Protocol Control codes are selected by a DIP switch DSW2-7 on the front panel.
See Section 3: Printer Configuration.

USING BASIC
It may be useful to test your printer using a BASIC program on a PC. You may also
write your actual production programs in BASIC. Whatever the reason, if you will be
working in BASIC, some of the following hints may help you get started:
1. Set the WIDTH of the output device to 255 characters to avoid automatically
sending <CR> and <LF> characters after every line. The command string
should be continuous and uninterrupted by <CR> and/or <LF> commands. The
examples given in this manual are printed on separate lines because they will not
fit on one line and do not contain any <CR> and/or <LF> characters. If these
characters are needed, they are explicitly noted by the inclusion of <CR> and
<LF> notations.
2. If you are using the printer’s RS232C interface, it is necessary to set the COM port
on the PC such that the CTS and DSR signals will be ignored. Send your OPEN
“COM” statement in the following way:
