Question

I need to print my Files found in my SPFolder directly to the Printer without recognizing the file type, so which Windows API to call and how to call it ?
Also what’s the process to launch the printing job when there are many files to print at the same time ?

Answer 1

You can use the system’s file associations to do the printing.

ProcessStartInfo psi = new ProcessStartInfo(documentFileName);
psi.Verb = "Print";
Process.Start(psi);

This relies on the machine having programs capable of printing all the document types you are interested in.
