Parameter Character - Any character from the ASCII table within the range 96-126 deci-
mal (" "  " through "~").  This character specifies the parameter to which the previous value
field applies.  This character is used when combining escape sequences.
Zn Termination Character - Any character from the ASCII table within the range 64-96 deci-
mal ("@" through "~”).  This character specifies the parameter to which the previous value field
applies.  This character terminates the escape sequence and is always in the form of a capital
letter, such as A, M, T, etc.
[Data]
Binary Data is eight-bit data (for example, graphics data, downloaded fonts, etc.).  The
number of bytes of binary data is specified by the value field of the escape sequence.  Binary
data immediately follows the terminating character of the escape sequence.
Following is an example of an escape sequence with a termination character and no parame-
ter character.  This escape sequence performs a single function of logical page orientation in
landscape mode.

Some escape sequences shown in this manual contain spaces between characters for 
clarity.  Do not include these spaces when using escape sequences.

Also, in the escape sequence a script "
l” is used to indicate a lower case "l" for clarity.
The following is an example of two escape sequences, each of which perform one function:
the first sets the logical page orientation to Portrait Mode, and the second sets the page size to
8 ½ x 11 inches. 
Esc & 
l 0 O and Esc & l 2  A
These two escape sequences can be combined into one escape sequence as follows:
Esc     &   
 
l l 
    1    O
