  This is a common problem encountered by many users. Most people send an 
  <ESC>-0 and expect the printer to turn off. but what is sent ? This 
  sequence sends 1BH 2DH 30H to the printer. the problem is the printer 
  want a "true" zero ,00H, not an ASCII zero, 30H. SO instead of sending
  <ESC>-0 send an <ESC>-<CTRL@> which will send a 1BH 2DH 00H to the printer
  and turn off the underline.
