Software The following software is provided for application development. Development Kits *1: 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.
https://www.omg.org/spec/UPOS 92 Software Description EPSON OPOS ADK This OCX driver can control POS peripherals using OLE technology.*1 Because controlling POS peripherals with vendor specific 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.
