The Caret Feature
Some environments do not allow the user to send the full range of
ASCII characters. The Caret feature is used to resolve difficulties
that may arise because of this.
Activating the Caret Feature
The Caret feature defaults to off on the LabelWriter's. To enable
the Caret feature, set the printer into terminal mode as instructed
in Appendix C and send a carriage return/line feed followed by
the characters ‘C’ and ‘1’. The program below demonstrates this.
OPEN "COM1:9600,N,8,1" FOR OUTPUT AS #1
PRINT #1, CHR$(13); CHR$(10);
PRINT #1, "C1";
Using the Caret Feature
When the caret feature is enabled, a LabelWriter will translate
any 3 digit characters following a caret character (‘^’) as the
number they express. For example, if the characters ^027 are sent
to the LabelWriter, it will interpret them as a single character
with a value of 27 (the Escape character).
When using the caret feature, three digit characters must always
follow the caret (^). Also, while the caret feature is enabled, the
LabelWriter will not work correctly with the LabelWriter EL
Windows or Macintosh print drivers.
