You would have to check the API documentation.

AFAIK PrintDocument is just a .NET wrapper on top of Windows printing system API
Do you want fast printing with the thermal printer? Then learn the printer's command language (ESC/POS, ZPL, EPL, whatever it is) and then create the needed commands to convert the image to such printer language and send it directly to the printer using http://support.microsoft.com/kb/322091[^]

Thanks for your reply. I tried example which is given in mentioned link but garbage text is printed instead of Image.

If you've specified the image as is, then it won't work. Remember that you have to send printer commands and the image needs to be converted to that by following the programming manual.

My customer did not provide me any manual with printer. Perhaps they purchased it from repairing shop. It's model POS-80c. I'm biggner in programming. Plz post any example.
