Hello Vasanth,
I havn't done this for a long time, but I can definitely suggest you few links which will help you in accomplishing this. Please have a look at this[
^] page. This company offers the necessary SDK. Similarly have a look at this[
^] site which actually offers a thermal printer. They also have a manula of printer commands that needs to get sent to print something. Each printer may have slightly different command set. So using direct printing means developing little printer specific code. You can also find a nice library[
^] here on CP, though it's developed using Compact Framework.
Regards,
