Overview
Apex printer comes equipped with a USB 2.0 slave port. Everything that can be done through the RS-232 port can now
be done through the USB port, using A to B type USB cable. You may print to or send commands to the printer from a
PC or any equipment that can act as a USB master.

Compatible Software
The host and printer communicate through a method called the "Virtual Com Port", in which a software intermediary called the
"driver" makes the USB connection look like a com port to the end-application. Consequently, all software that communicates
through the com port is compatible. You may continue to use legacy software, such as the TeraTerm terminal emulation
software.
