Chapter 5 Application Development Control Method for Devices The followings are methods for controlling devices. • ESC/POS command: This can control the EPSON TM printer, cash drawer, and customer display. (For details, refer to "ESC/POS command" on page 160.) • APD4 (Windows printer driver): This driver can control TM printers controlled by TM-H6000IV-DT, cash drawers, and customer displays. The Status API (Epson original DLL) that monitors printer status and sends ESC/POS commands is also attached to this driver. • OPOS ADK: This OCX driver can control POS peripherals using OLE technology*1. Because controlling POS peripherals with original commands is not required on the application side, efficient system development is possible. • OPOS ADK for .NET: OPOS ADK for .NET allows you to develop applications that are compatible with Microsoft POS for .NET. When developing applications, use a separate development environment such as Microsoft Visual Studio .NET. *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 drivers. It is not a driver to be used for printing from commercial applications. 5 159
