The Caret Feature required because this amount exceeds the longest possible string of bitmap data bytes that the LabelWriter printer expects. See Also ESC B ESC D ETB Expression ASCII SYN d1...dn Decimal 22 d1...dn Hex 16 d1...dn Parameters d1 ... bytes of bitmap print data (max 56 bytes for LabelWriter dn = SE450 print heads). n 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). 53
