Definition of a printer command

The commands covered in this chapter are classified as escape sequences.

The escape sequence is a type of printer command that gets its name from its initial character, the escape character. (This is not the same as the escape key on your keyboard.) Escape is a non- printable control code with the hexadecimal ASCII value 1B.

In XES mode, the 4213 recognises the escape character as a signal to indicate that the letters and numbers making up the rest of the sequence are not text to be printed, but instructions to be executed.

Command syntax as expressed in this chapter

The parts of the printer commands, or escape sequences, will be shown as follows:

EThe escape character is represented by this character.

+D,The literal, instruction part of the command. Punctuation marks in commands serve as delimiters.

HUser-entered variables are represented by an abbreviation.

comment Other user-entered information, such as file names or Summary Sheet comments, are also represented in italics.

LLine end (carriage return and line feed).

Note: The command must be entered in upper or lower case exactly as it is shown. Do not enter spaces between characters unless specified.

Three types of escape sequences

There are three basic types of escape sequences:

1.Job control commands

2.Simple commands

3.Commands with user-entered variables.
