2.4 PRECAUTIONS FOR USE
Always print the two-dimensional bar code and ladder bar code (its bar is to be printed verticality to
the printer) within 0 to 40°C to ensure the bar code's reading accuracy.
The two-dimensional bar code and ladder bar code printing always requires the low speed mode to
ensure its reading accuracy. Set the print speed to the low speed mode by using Motor Speed
Select (GS 'E') command.
The height of the ladder bar code requires over 10 mm to ensure its reading accuracy.
To print data at a temperature of 15°C or lower, be sure to set data for black printing to 78 mm or
less (see figure below).
At a low temperature, the total number of black printing areas (w1 + w2 in the figure above, for example)
should not exceed 78mm for parts having high printed ratios* (including the ladder bar code part).
Be aware, in particular, that reverse printing and ruled line tend to increase the ratio.
* Parts where many black dots are used when viewed in the direction vertical to the paper feed direction.
Use of the battery pack at low temperature will run out of power in a shorter time.
When printing ruled lines, a 2-dot configuration is needed. In case of a 1-dot configuration, the
printed lines may be invisible.
Always use the printer within the shadowed range depicted in figure below Relationship between
Temperature and Humidity.
