Format bar code for printing
Bar code printing can be used as ticket data carrier instead of, or in addition to, magnetic
encoding.
NOTE!
– To produce sharp code bars, the TTPM3 printer automatically reduces
the print speed by approx. 50% when printing tickets with east and
west oriented bar codes. This speed reduction is only valid for bar
widths 1 and 2. Wider bar codes are printed at full speed.
Bar code data is treated as fixed data. You can however replace a bar code by overlaying
the previous data with new bar code data on the same X- and Y-coordinates. This way you
avoid deleting the complete ticket with a reset (!C) when you want to update the bar code.
The syntax for defining and downloading of bar code data is as follows:
!F C <orientation> <xpos> <ypos> <bar 1> <height> <bar 2> <type>_ <”bar code data”>
!F
Command to load print parameter information
C
Indicates bar code mode
<orientation> Indicates print orientation. Can be north (N), east (E), south (S), or west
(W).
xpos
Starting position (pixel) for the upper, left-hand corner of the first code bar
in the string. Automatically rounded off to be divisible by 8, (first bit in a
byte).
ypos
Starting position (pixel) for the upper, left-hand corner of the first code bar
Bar 1
Width in pixels of both black and white bars, range 1–16.
For EAN13 and EAN/Code 128 the value must be set to 1.
For Code 39 and Code 2-of-5 this sets the
wide bars
.
height
Code bar height in pixels
Value
1 = 16 pixels =
2. 7 mm
2 =
32 pixels =
5.3 mm
3 =
48 pixels =
etc.
4 =
64 pixels =
5 = 80 pixels =
…
16 = 256 pixels =
42.7 mm
Bar 2
Width in pixels of both black and white bars, range 1–16.
For EAN13 and EAN/Code 128 the wide/narrow ration is fixed and this sets
the width of the entire code.
For Code 39 and Code 2-of-5 this sets the
narrow bars
.
