1.1 The SATO RISC Programming Language
A programming language for a printer is a familiar concept to most pro- grammers. It is a group of commands that are designed to use the internal intelligence of the printer. The commands, which are referred to as RISC Command Codes, contain
The command codes used by the SATO RISC Printers 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.”
1.3 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
