PROGRAMMING LANGUAGE

A programming language for a printer is a familiar concept to most programmers. It is a group of commands that

are designed to use the internal intelligence of the printer. The commands, which are referred to as SATO

Command Codes, contain non-printable ASCII characters (such as <STX>, <ETX>, <ESC>) and printable

characters. These commands must be assembled into an organized block of code to be sent as one data stream to

the printer, which in turn interprets the command codes and generates the desired label output. The programmer is

free to use any programming language available to send the desired data to the printer.

The printer command codes used are based upon “Escape” (1B hexadecimal) sequences. Typically there are four

types of command sequences:

<ESC>{Command}

These commands generally tell the printer to perform a specific action, like “clear the memory.”

<ESC>{Command} {Data}

Commands with this format tell the printer to perform a specific action which is dependent upon the following data,

like “print X labels”, where the value for X is contained in the data.

<ESC>{Command} {Parameter}

These commands set the operational parameters of the printer, like “set the print speed to 3.”

<ESC>{Command} {Parameter} {Data}

Some commands can contain both Parameter and Data elements, such as “print a Code 39 symbol containing the

data.”
