♦Printing Labels
2.0 Introduction
Labels can be generated using RS-232 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.
2.1 Programming Commands
In order to be ready for a command sequence, the printer must first receive a special character called an “attention getter” that 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.
