Hi Mike,
I want to print a Vietnamese document, but I do every way it's still wrong.
Text string ex: "Ta đã từng hứa yêu nhau đến muôn đời sau
Anh vẫn luôn khắc sâu nhưng hôm nay ân tình phai màu
Còn gì nữa đâu và đành buông lơi những câu
Ta phải xa rời nhau như hoa kia dần úa màu. ."
Please see the picture.

Please help me!
Thanks!

@Daund - this is an old change that added TCVN-3 output on Epson-branded printers. Character encoding is different for every printer, and you won't get answers on closed issues.

Can you please file a new issue including details of your printer that indicate whether it is capable of printing Vietnamese, plus a self-contained sample of code, and details of which debugging you've tried so far?

If you are interested in a quick work-around, search 'ImagePrintBuffer' on the issue tracker, I posted an example earlier today for the Laptop script that can be adapted for Vietnamese!
