I am using the Microsoft Point of Service option to allow our POS application to print to OPOS compatible printers. &nbsp;And generally it works well. &nbsp;However, we have a customer that wishes to print Thai characters. <br />
<br />
The printer I purchased for them is the Asian variant of the TM-U220A. &nbsp;According to the specifications. this have the Thai character set built in. &nbsp;However, when I send Thai characters, they do not print I get the ? unknown character printed instead.<br />
<br />
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.<br />
<br />
All the documentation tells me this should work, but it doesn't. &nbsp;Can anyone help?<br />
<br />
Thanks

How to Print Thai Characters using OPOS

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

A printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media. Traditional printers are being used more for special purposes, like printing photographs or artwork, and are no longer a must-have peripheral; 3D printing has become an area of intense interest, allowing the creation of physical objects. An image scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.
