This is a frequently asked question, please do basic research such as a google search before you ask a question.

The answer is that you can't. If the client wants to print something then they will. Would you want websites forcing things to your printer without your intervention?

The C# code runs on the server. It cannot access printers connected to the client. Unless you can connect the printer directly to the web server, and run your application pool as a user which has the printer configured, that's not going to work.

Code running on the client cannot print anything without the user's consent. If it could, that would be a major security vulnerability. Imagine what would happen if you visited a malicious site, and your company printer suddenly started churning out page after page of porn...

Sometimes tricks comes with a cost. If you can afford your application to be a single browser supported i.e. Google Chrome than you can use Silent/Kiosk Printing feature of Chrome.

A bit detailed article can be found Here

Or you can search on Google for further information.

Hope it helps. :)
