Epson ePOS SDK
The command for the buzzer function is provided in each SDK library. For details, see the user's
manuals provided with each SDK.
Note
For details on setting the optional external buzzer, see “Connecting an Optional External Buzzer” (page
3-13).
5.4 Software
The following software is provided for application development.
5.4.1 Development Kit
*: 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.

5.4.2 Drivers
Software Description
Epson ePOS SDK This is a development kit for controlling TM printers from native applications of
smart devices or web applications. This includes libraries, manuals, and sample
programs.
for Android

for JavaScript
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 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.

Printer Driver (APD)
In addition to ordinary Windows printer driver functions, this driver has
controls specific to POS. The Status API (Epson original DLL) that
monitors printer status and sends ESC/POS commands is also
attached to this driver.
