I am using the Microsoft Point of Service option to allow our POS application to print to OPOS compatible printers. And generally it works well. However, we have a customer that wishes to print Thai characters.
The printer I purchased for them is the Asian variant of the TM-U220A. According to the specifications. this have the Thai character set built in. However, when I send Thai characters, they do not print I get the ? unknown character printed instead.
I am using the Epson OPOS.Net ADK, and it also says I can print in Thai, but when I check the printer settings, the list of code pages does not include the Thai one.
All the documentation tells me this should work, but it doesn't. Can anyone help?
