Using the Zebra SDK, you should use the CPCL print language to send down Thai characters.
Use the following CPCL command to enable Thai encoding:
! U1 COUNTRY CP874
You can reference section 22.214.171.124 in the CPCL manual for Link OS printers for more information.
Hope this helps,
Do we need to install any font in the Printer? Im using IMZ320.
Unless you bought a printer with an Asian font already installed, you do need to install a separate font. You can either use TTF or CPF fonts in CPCL and download them with the Font Downloader tool in the Zebra Setup Utility. You also need to use the CP874 character encoding to make it work. Some of our printers that get sold into Asia may already have some Asian fonts installed.
