EPSON Advanced Printer Driver (APD):
In addition to ordinary Windows driver functions, this
driver has controls specific to POS, such as controls for
paper cut, a cash drawer, and customer display. The
Status API (Epson original DLL) that monitors printer
status and sends ESC/POS commands is also
attached to this driver.

with original commands is not required on the
application side, efficient system development is
possible.

EPSON JavaPOS ADK:
JavaPOS is the standard specification which defines
an architecture and device interface (API) to access
various POS devices from a Java based system. Using
JavaPOS standard API allows control with Java-based
applications of functions inherent to each device. A
flexible design with Java language and JavaPOS
enables many different types of computer systems,
such as stand alone or network configuration, to use
a same application. You can use JavaPOS to build
applications and drivers independently of platforms.
This allows flexible configurations using thin clients to
meet the system requirements.
