8.5 ^B7 PDF417 BAR CODE
Forma: ^B7o,h,s,c,r,t
o = Font rotation
N : 0°
R : 90°
I : 180°
B : 270°
When omitted: Value of ^FW
* The point of origin differs depending on the coordinate designated in ^FT and ^FO.
h = Bar code height for individual rows (in dots)
203-dpi printer: LE840
1 to 80 dots
300-dpi printer: LE850
1 to 120 dots
When omitted: Value of ^BY
*1 Since this is the height of the whole barcode when the number of rows is omitted, the maximum
value is 9999 dots.
*2 If the value after dot-to-mm conversion exceeds 10 mm, it is corrected to 10 mm.
s = Security level
0 : Error detection only
1 to 8 : Correction and error detection
When omitted: 0
c = Number of data columns to encode
1 to 30
When omitted: 1:2 row-to-column ratio (aspect ratio)
r = Number of rows to encode
3 to 90
When omitted: 1:2 row-to-column ratio (aspect ratio)
t = Truncate stop pattern
Y : Yes
N : No
When omitted: Y
*1 The point of origin for the rotation of 180° or 270° differs between Zebra and Oki Data.
*2 When large-size data (e.g. 1850 English characters/1469-byte binary data) is sent, the bar code
that can be printed with Zebra may not be printed with Oki Data (due to the difference of the
encoding system for PDF417).
*3 When both parameters c and r are omitted, the numbers of columns and rows are calculated based
on the data size and the aspect ratio.
*4 When either parameter c or r is omitted, the value of the omitted parameter is calculated based on
the data size and the aspect ratio for the specified value.
*5 If the command is sent without setting data (only ^FS and ^XZ are set while ^FD^FS and ^FD are
not set), the barcode will not be printed.
*6 The amount of data that can be contained in “No. of columns x No. of rows” for Oki Data is smaller
than that for Zebra by a few bytes. (The number of bytes varies depending on the numbers of
columns and rows.)
If the numbers of columns and rows (other than 0) are specified and the above condition is met, bar
codes are not printed with Oki Data. When the number of rows is set to ‘0’ (or omitted), it may be
larger than that for Zebra.
