Purpose Deleted character results in a blank space at the corresponding character position.

Comment The Delete code deletes the corresponding character in the print buffer. As shown in Table 14 below, the four delete control codes are used to delete DATE from the print line.

NOTE: In order for this to work correctly, the printer must be configured for carriage return only. If configured for a carriage return and a line feed, the contents of the buffer are printed on receipt of the CR code.

Table 14. Delete Example

Enter in Print Buffer	Printed Result
INVOICE DATE(CR)	INVOICE
SSSSSSSSDDDD(LF)
Key:	S = Space (hex 20);
	LF = Line Feed (hex 0A);

	D = Delete (hex 7F)
