Parameters

Parameter	Meaning
`x,y`	Top-left corner of the barcode, in dots
`rot`	Rotation code 0–3 in clockwise quarter turns, as in the A command
`type`	Barcode type code: 1 Code 128, 3 Code 39, E30 EAN-13, UA0 UPC-A in the preview
`narrow`	Narrow bar width in dots; sets the module width of the drawn barcode
`wide`	Wide bar width in dots; accepted but not used by the Labelixa preview
`h`	Bar height in dots, without the human-readable line
`B/N`	B prints the human-readable line under the bars, N leaves it out
`"data"`	Barcode data in double quotes; empty data is skipped with a warning

Common mistake

Using the TSPL/CPCL type name: in EPL, Code 128 is type 1, not 128. B50,150,0,128,3,7,120,B,"123456" names an unsupported type and the preview skips the barcode.
