Escape sequences

3-10
Escape sequences are multi-character commands preceded by
the escape character.
parameters.

Escape sequences with parameters

Escape sequences with parameters either access a specific feature
of the printer, such as a font, or transmit variable data such as
margin settings. These escape sequences are subdivided as
follows:
Escape character
•

Variable sequence character

•

Group character

•
Numeric variable
•
Parameter character
•
Final parameter character
•
Binary data.
•

Escape sequences without parameters

The escape sequences without parameters perform an action
such as resetting the printer. These commands are typically two
characters long: escape followed by a character between
hexadecimal 30 and 7E (decimal 48 and 126).
Variable sequence character
The variable sequence character indicates that the escape
sequence contains a parameters with variable data. The variable
sequence character must be in the range of hexadecimal 21—2F
(decimal 33—47).
Group character
The group character determines the type of operation to be
performed by the printer. The group character falls in the range
of hexadecimal 60—7E (decimal 96—126).
