● Parameter 
    a        [Narrow bar width]  =    Valid range    :  01 to 12 dots 
    b        [Barcode height]    =    Valid range   :  001 to 999 dots 
    n        [Print data]       =    Barcode data 
 
[Coding example]  Narrow bar width: 02,    Barcode height: 120 
<A> 
<BT>103060306 
<V>100<H>200
<BW>02120*ABCD*
 
<Q>2 
<Z> 
 
[Notes] 
1.  Barcode  character  pitch  is  available  for  CODABAR(NW-7),  CODE39,  Industrial  2of5  and  Matrix  2of5.  To  specify  barcode 
character pitch, insert the Character Pitch <P> command right before barcode symbology.   
When <P> is omitted, character pitch will be equal to narrow space width. 
 
e.g.1) When the narrow space value that was specified at <BT> is [3]:   
Character pitch specification (None or 0, 3)   x    Narrow bar width (2dots)  = Character pitch (6dots) 
e.g.2) When the character pitch is specified:   
Character pitch specification (2)          x    Narrow bar width (3dots)  = Character pitch (6dots) 
2. If there is no registration of Bar width ratio <BT> command, barcode based on pre-registered bar width ratio of narrow and wide 
bars will be printed. Note that specification of <BT> is required beforehand to print.   
  3. For print data of barcode symbology, refer to the code table of each barcode. 
 
[Tips] 
   1. If the value other than valid range is set, command error will occur and barcode will not to be printed. 
   2. Increasing narrow bar width may exceed the print area. 
3. Scanner may not read the barcode with valid character pitch when the Character Pitch <P> command is increased.     
  Also, increasing the narrow bar width may cause the same type of problem. For more information, refer to the documentation of 
your scanner. 
4. For specifying the narrow bar width, consider the reading compatibility of scanner beforehand. 
5. Adjust the Print Speed <CS> or Print Darkness <#E> commands in case of scanner reading problem. 
6. If Start/Stop characters are not included in print data in the specification of CODABAR(NW-7) or CODE39, the print of barcode 
will be performed; however, scanner cannot read it.
