greater than the difference in signal (the noise) resulting from the optical discontinuity in
the material – especially if there are pre-printed areas around the sensors.
To have an indication of the transparency / reflective ness of the material, the correct sen-
sor should be chosen and a test label printed with the command
/U00
. The material
should first be correctly positioned under the sensor.

/Qbbbllllg.. g
The
/Q
command is used to download a rectangular graphic bitmap and insert it with its
top left corner in the position of the last command
/E
.
It must be followed by 2 parameters which define the dimension of the bitmap and by the
binary data which represents its contents as follows:
bbb
Number of bytes (groups of 8 adjacent dots) which
make up every single line of the bitmap, three digits
(values: from 001 to 999 or from -01 to -99);
llll
number of lines which make up the graphic block, (val-
ues: from 0001 to 9999);
g..g
data which defines the bitmap.
If the bbb parameter is positive, the data flow will consist of a series of bytes with a total
which is the number of bytes per line multiplied by the number of lines. If the bbb pa-
rameter is negative, each byte is replaced by a couple of hexadecimal characters (from 00
to FF) which represent the binary value. Each line is terminated by a sequence of CR+LF.
This alternative alphanumeric format is less efficient than pure binary ( the flow of data is
more than double the length) but is very useful when the external computer cannot man-
age binary data but only ASCII characters. The flow of bytes is configured as follows:
each bit represents a single dot (1=print, 0=blank), and the most significant bit is on the
left. The bytes of each line are ordered from left to right and from top to bottom.
The block will be automatically truncated if it exceeds the lower margin of the printable
area, depending on the rotation selected.

/Roc
The
/R
command is used to set the orientation and the colour of the barcode, lines, borders
and graphics.
It must be followed by 2 single digits with the following significance:
o
orientation (values: 0=normal, 1=90° clockwise, 2=180°, 3=270°);
c
colour in respect to background (values: 0=black, 1=white 2=inverted).
The rotation of parameter
o
is ignored by the
/L
command which contains an orientation
parameter.
