Escape sequences

Escape sequences are multi-character commands preceded by the escape character. Escape sequences may or may not have 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 21Ð2F (decimal 33Ð47).

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 60Ð7E (decimal 96Ð126).
