This chapter describes how to control the printer and gives information useful for printer application
development.

Controlling the Printer

The printer supports the following command systems:

• ESC/POS

Users can control the printer by using the aforementioned command, or the following development kits or
drivers.
• EPSON Advanced Printer Driver (APD)
• OPOS ADK
• OPOS ADK for .NET
• Epson ePOS SDK

ePOS-Print XML

ePOS-Print XML is the Epson original control command system for POS printers defined in XML. With ePOS-
Print XML commands, you can print in environments where http communication is available and from OS
applications. For detailed information about ePOS-Print XML, see the ePOS-Print XML User's Manual.
ESC/POS
ESC/POS is the Epson original printer command system for POS printers and customer display.
With ESC/POS commands, you can directly control all the printer functions, but detailed knowledge of printer
specifications or combination of commands is required, compared to using drivers and applications.
For details of ESC/POS, see the ESC/POS Command Reference. The ESC/POS Command Reference can be
accessed at the following URL.
