printing in windows mobile application development using c#

Question

Hello, 

i've been working as programmer, Recently i've been appointed to a factory project in which the factory gives the material to vehicles to sale.

In each vehicle a person should hold a mobile or any device for reporting sales.

I'm using C# in visual studio for this project, i've seen all success till now, but after sales the vehicle person needs to print the invoice.

I was stuck there, i've never tried windows mobile development, so i'm totally unaware of printing in this scenario.

I need help urgently, please....
