Bar Codes
Introduction
The printer contains a number of bar code generators, which can produce
highly readable bar codes in four different directions.
However, a general rule which applies to all thermal printers is that it is more
difficult to print a bar code with the bars across the web (ladder style) than
along the web (picket fence style). Therefore, to ensure a highly readable
printout, we must recommend that you, when printing bar codes with the bars
across the web (ladder style), do not use narrow bars less than 3 dots.
No such restrictions apply for bar codes with the bars along the paper web
(picket fence style).
Another factor, that affects the printout quality of the bar codes, is the print
speed. Generally, a lower print speed gives a better quality, especially for
ladder style bar codes and at low ambient temperatures. Do not use a higher
print speed than necessary and consider the overall print cycle time. In some
instances, a lower print speed may actually gives better overall performance.
We recommend you do your own tests with your unique applications to find
the best compromise between printout quality, performance and media.
