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.
On this printer, ePOS-Print XML is only supported by a Wi-Fi model.
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 TM-P20 printer functions, but detailed knowledge of printer speci-
fications or combination of commands is required, compared to using drivers and applications.
For detailed information about ESC/POS commands, see the ESC/POS Command Reference.
To use ePOS-Print XML or SDK for JavaScript, set ePOS-Print to Enable in EpsonNet Config (Web Ver-
sion) beforehand.
For details about EpsonNet Config (Web Version), see "EpsonNet Config (Web Version)" on page 65 .
