Chapter 4 Application Development Information
Software
The following software is provided for application development.
Development Kits
* OLE technology developed by Microsoft divides software into part blocks. The OPOS driver is presupposed to be used
with a development environment, such as Visual Basic, unlike ordinary Windows printer drivers. It is not a driver to be
used for printing from commercial applications.
You can acquire documents regarding the UnifiedPOS from the following link.

Software Description
EPSON OPOS ADK This OCX driver can control POS peripherals using OLE technology.
*
Because
controlling POS peripherals with original commands is not required on the
application side, efficient system development is possible.
EPSON OPOS ADK for .NET The OPOS ADK for .NET is a POS industry standard printer driver compatible with
Microsoft POS for .NET.
It allows you to develop applications that are compatible with the UPOS (Unified
POS) specification.
When developing applications, use a separate development environment such as
Microsoft Visual Studio .NET.
EPSON JavaPOS ADK (Windows/Linux) 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.
Epson ePOS SDK This is a developer kit to control applications, native applications for smart
devices, and printers. This includes libraries, manuals, and sample programs.
