Hey printing junkies need some pointers to send me in the right direction for this development.

I am developing an epos system for a local shop which we are later going to tie into an ecommerce site. 

The front end of the epos system is going to be WinForms so we can handle USB devices easily and we are going to use a WebForms/MVC admin console.

One area we are inexperienced in is printing. We need to print barcodes, and wish to do this via the admin console (web based).

So (finally) the question. Where do we start looking for code that will allow us to print directly to a connected printer from the server (IIS) instance of .net from the webforms.
