Firmware Characteristics of the Controller
The TH230 printer is controlled with the aid of control sequences, i.e. a series of
characters. The standard setting is thus overridden, which means that you are able to set
many print functions individually if the standard values do not correspond to your
requirements. Possible changes are, among others, the selection of different line feed
sizes and the printing of various graphics. You will see that it is very simple to control the
printer according to your own personal requirements. However, a precondition for proper
use is the correct installation and/or configuration of the system. In addition, you should
be familiar with the operating system of your computer.
With the interfaces USB 1.1 (USB 2.0 compliant) or RS232, all the status information’s can
be called up using the different control commands. Via this interface, it is possible to
synchronize the user software and the printing properties. The TH230 printer supports an
ESC POS
TM
command set.
Line feed
The line feeds of the TH230 printer are initiated by the control commands LF and ESC d.
The line spacing between 2 lines can be set by the control command ESC 3. The default
value after reset or power on is 3.37 mm, which equals 27 micro steps. One micro step
equals one dot distance of 1/203”.
