9. Barcode Specification Outline
From the specification (B, D, BD) followed with ESC, barcode specification can change every type of bardcode printing and every barcode ratio,
includes print out guide bar as well as explanation character.
Content change based on specification, use it after understand the content of this page and the following page.
Below shows the outline of each specification (B, D, BD)

(1)Barcode Ratio
Barcode is formed by narror bar, wide bar, narror space and wide space. Barcode ratio refers to the ratio between narrow bar (thin bar) and wide bar
(thick bar).
Barcode Specification (ratio 1: 3) <B>
Barcode of Barcode Ratio 1: 3 is formed by thick bar "3" against thin bar "1".
Barcode Specification (ratio 1: 2) <D>
Barcode of barcode ratio 1: 2 is formed by thick bar "2" against thin bar "1".
Barcode Specification (ratio 2: 5) <BD>
Barcode of barcode ratio 2: 5 is formed by thick bar "5" against thin bar "2".
When barcode ratio is specified optionally, register the ratio by barcode ratio specification <BT>, label can be printed by ratio specifed Barcode
Print Specification <BW>.
(2)Thin Bar Width and Barcode Height
Thin bar width is the thickness of narrow bar, while barcode height refers to the height of barcode.
For example, if thin bar width is printed by printer head density of 12 dot/mm (3056dpi), the thickness of narrow bar will become 0.083mm and
unreadable at the barcode scanner. At this point specify the thin bar width at 2, the thickness of narrow bar will become 0.166, the read aptitude
will be improved.
It is necessary to set thin bar width to fit to the printer head density and barcode scanner function.
Barcode ratio specified the thickness of bar by "thin bar width" specification.
Example: if barcode ratio =1:3, thin bar width:3 (dot), barcode ratio becomes 3:9
Barcode height is to specify the height of barcode, it set an appropriate height based on scanner form.
(3)Character Gap
Character gap is the space to differenciate between the barcode character and the following barcode character.
To specify character gap, barcode specification <B><D><BD> becomes valid by specifying Character Ptich Specification <P> right before
Barcode Print Specification <BW> at ratio registration. If that specification is not done, it turns out to be default value (2 dot).
①NW-7
The following is the barcode type for character gap to specify.
②CODE39
③Industrial 2 of 5
④Matrix 2 of 5
Character gap is the multiplier of value get from Chracter Pitch Specification <P> and Thin Bar Width.
Example: if Character Pitch Specification <P>3, thin bar width (2 dot), it turns out to be Character Pitch
