♦ Printing Labels
4.0 Introduction
Labels can be generated using RS-232C or parallel communications
to a host computer or a PC with a compatible labeling software
package. This chapter explains some of the basic programming
commands that are required when writing programs to generate
label formats. A programmer's manual can be obtained by mailing
or faxing the request card located in the back of this manual.
4.1 Programming Commands
In order to be ready for a command sequence, the Printer must first
receive a special character called an “attention getter,” this character
informs the Printer that it is about to receive a command and the
type of command it will be. Immediate Commands, System-Level
Commands, and Font-Loading Commands each have their own
attention getter. The attention getter character is followed by a
command character that tells the Printer what action to take.
