/dev/console is a virtual terminal just like /dev/tty*. It really has nothing to do with "printk" in the kernel (really). It's just one of the many places where things "printed" in the kernel can be displayed. And, yes, the console is a two-way terminal emulator. It is the standard-input, standard-output, and standard-error, for the init process. Normally init doesn't respond to any input from the console, but during boot it does so that you can try to fix various errors.
