Chapter 1 Free Format
Control Code Equivalents
When Free Format is turned ON, GPL control code equivalents are treated as
actual ASCII control codes. For example ^! functions in the same manner as
the ASCII control code SOH. If control code characters need to be passed to
the printer in Free Format Mode, use the control code equivalents shown in
Table 1.
