The Caret Feature
Some computing environments do not allow the user to send the full range of ASCII
characters, limiting output to printable characters only (20h - FFh). 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 printer. To enable the Caret feature, set
the printer to terminal mode 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";
Refer to Configuration Menu for more information about Terminal mode.
Using the Caret Feature
When the caret feature is enabled, the LabelWriter printer will translate any three-digit
characters following a caret character (^) as the decimal value the digits expressed. For
example, if the characters ^027 are sent to the printer, they are interpreted as a single
character with a value of 27 (the Escape character).
