D.1.2 EPSON OPOS ADK
EPSON OPOS ADK supports the development environment necessary for OLE for Retail POS
(OPOS) application development by OPOS Control proposed by the UnifiedPOS Committees
and supplies a printer driver (OCX) conforming to OPOS.
When developing an OPOS confirmed application, use the following control methods. EPSON
OPOS ADK has the following features.
❏ EPSON OPOS ADK supports not only the OPOS Control (CO + SO) proposed by the
UnifiedPOS Committees but also totally supports the OPOS application development
environment such as utilities for installation and setup, the contents necessary for
development, such as sample programs and manuals, and also the function of Log when
debugging, and silent installation, which enables easy installation for a targeted PC.
❏ EPSON OPOS ADK supports DirectIO with parameters for unique functions exclusively for
TM printers by EPSON. Also the power notice function, offline buffer clear processing, and
device irregular processing that has been taken into account by developers are supported by
the driver; these can reduce the number of application steps.
Note:
For detailed information for the API functions, refer to “OLE for Retail POS Application Programmer’s
Guide (APG)” issued by the UnifiedPOS Committees.
