(4) Rotational angles of a barcode
Origin
0°
NOTE: If a barcode is rotated at 90° or 270°, the print density may become lower
in relation to the bar height. A barcode with a height of 14 mm or less
should be used. When a barcode with a height of over 14 mm is used,
the print quality is not guaranteed.
Rotational angle of a two-dimensional code
Point of origin
0°
(5) Barcode height
(6) Numerals under bars
Numerals are provided under bars depending on the parameter for numerals
under bars. Standard fonts are used.
(7) Since the start/stop codes are not automatically attached when using NW7, they
should be included in the data to be sent as required. Although no start/stop
codes are attached to data, a barcode is drawn.
When using CODE39, the first and last characters of the data are checked.
Unless the characters are not "*," "*" is automatically attached. When the host
sends data while attaching "*" as the start/stop codes, a barcode is drawn.
(8) When Interleaved 2 of 5 is selected and the number of data length digits is odd, 0
is automatically added to the beginning of the data, to change the number of data
length digits to even.
