Escape Sequences
An escape sequence (two or more characters of information) lets you change the way
the printer is currently printing. Like a control code, it gives you control over the printed
output. The escape sequence begins with the character ESC (decimal 027,
hexadecimal 1B). The printer recognizes this character as the beginning of a printer
command signaling that the information following is control information and not data
to be printed.
Printer Command Parameters
A command parameter sets the value for a command. This value stays constant until
either a different value resets the command or a command resets the printer to its
default values. For example, after the printer receives a command that selects a right
margin beginning at column 63, the right margin of each printed page begins at
column 63. The margin remains constant until a right margin command with a different
value resets the margin, or the printer is reset.
In this section, command parameters are indicated by a lowercase n. Usage Notes
explain how to compute this parameter.
