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).
