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 RS232 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:
