C# Windows Form Send To Printer

I have a project where I have a bunch of data rendered to the grid in a windows form. The user then requests to export to excel or pdf which then saves the data in the corresponding format to the computer. What I want to be able to do is have the program export the data to disk and then send it to a printer. Any help in getting the printer portion going would be greatly appreciated. Must be done in C#, can make use of any open source dlls as long as its compatible with windows forms. Only have $30 to spend on this project so please only bid that amount. First person that is able to send me a demo of automatically sending a file to a printer will win the project. Good luck.
