Combining escape sequences
Escape sequences may be combined into one escape sequence
string. There are three important rules to follow when combining
code:
1
The first two characters after the
?
character (the parameterized
and group characters—see the figure on the previous page) must
be the same in all of the commands to be combined.
2
When combining escape sequences, change the uppercase
(termination) character in each individual escape sequence to
lower case.
3
The final character of the combined escape sequence must be
uppercase.
The following is an example of an escape sequence string that would
be sent to the printer to select legal paper, landscape orientation, and
8 lines per inch:
?&l3A?&l1O?&l8D
The following escape sequence sends the same printer commands
by combining them into a shorter sequence:
?&l3a1o8D
