Printing Bar Codes
Bar code printing can be used as ticket data carrier instead of, or in addition to, magnetic
encoding.
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 C Format bar code printing
Note • To produce sharp code bars, the TTPM2 printer automatically reduces the print speed
by approx. 50% when printing tickets with east and west oriented bar codes. In firmware
version 3.50 and higher, this speed reduction is only valid for bar widths 1 and 2. Wider bar
codes are printed at full speed.
!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.
