Yes on copy and paste, though you have to use a text box in the browser window (a menu on the left side) to mess with the clipboard. It's not ideal, but it's possible.

I cannot remember drag & drop files off the top of my head, but I seem to think no.

Not sure about local printer.

Printing is enabled by they system generating PDFs that the browser automatically downloads. It actually works pretty slick.

File drag-and-drop can be set up via a couple of different mechanisms, and isn't easy to get going, but works fine once you have it going.
