Use Dymo Labelwriter Turbo in .net

[deepa2Apr]

Hi,

I'm trying to use a Dymo LabelWriter Turbo (Software version 4.1.0.0) on Windows XP, in my C# code. I'm able to detect the printer through my code. However it doesnt print anything. It tries to print, but the label doesnt have any text on it. Can anyone help me?

Please find my code below.
