how to print files from the client side in asp.net without opening

[chatwithlal]

hi all, I have an application which is used for uploading ,viewing,printing and accessing those files. I have done uploading files to server.I can view also.. I am showing the files in a datagrid.I have to select the mutliple documents from grid and print it out. But I have to print the files without opening in client browser to a network printer or client side printer. Even if it will open in browser then after automatic printing of file that window will close which is used for open the file. how can i do it with asp.net? pls give me some sample code and links.. lal
