Barcode Commands
In barcode specification, print of various barcodes, change of bar width ratio, and print of guard bar
or human-readable information can be performed by the specification (B, D, BD) after ESC.
The contents may vary depending on the specification. This and next page should be read closely
and followed.
Refer to the table below for the specification of B, D, and BD.
[Specification of Bar Width Ratio]

(1) Bar Width Ratio
Barcode is composed of Narrow Bar, Wide Bar, Narrow Space and Wide Space. Bar width ratio is
the proportion of Narrow Bar and Wide Bar.
- Barcode specification (Ratio 1:3) <B>
This barcode is composed of Narrow Bar [1] and Wide Bar [3].
- Barcode specification (Ratio 1:2) <D>
This barcode is composed of Narrow Bar [1] and Wide Bar [2].
- Barcode specification (Ratio 2:5) <BD>
This barcode is composed of Narrow Bar [2] and Wide Bar [5].
If specifying bar width ratio for your own convenience, register the ratio with Bar Width Ratio <BT>
and print labels with Print of Specified Bar Width Ratio <BW>.
(2) Width of Narrow Bar and Height of Barcode
Narrow bar indicates the narrow bar width, and bar height indicates the height of barcode.
For instance, printing narrow bar for 1 dot in head density of 8 dots/mm (203 dpi), the narrow bar
width will be 0.125 mm and barcode scanner may have a reading problem. To avoid this problem,
set the narrow bar to 2 dots so that the narrow bar width will be 0.25 mm and this will improve the
scanner reading condition.
There is a necessity to set the narrow bar width based on head density of this product or
performance of barcode scanner. In bar width ratio, [Narrow bar width] specification sets the width of
bar.
e.g.)
When bar width ratio = 1:3 and narrow bar width is 3 dots, bar width ratio becomes 3:9.
Bar height is to specify the height of barcode, and proper height based on the scanner type can be
set.
