Syntax of Escape Sequences
There are two forms of PCL escape sequences: two-character
escape sequences and parameterized escape sequences.
Two-Character Escape Sequences
Two-character escape sequences have the following form:
?
X
where “
X
” is a character that defines the operation to be performed.
“
X
” may be any character from the ASCII table within the range
48-126 decimal (“0” through “~” - see Appendix A). For a list of the
two-character escape sequences supported by the printer, refer to the
“PCL Feature Support Matrix” in Chapter 1 of the
PCL 5 Comparison
Guide
.
Following are examples of two-character escape sequences:
? E

default settings.
