Not quite. We can read DNA sequences, but we can't reliably write them yet beyond a few dozen base pairs. In fact, we can't even take a fully-assembled human genome and "make a baby as output." That process is called cloning, and it is fraught will all manner of practical and ethical difficulties. But there's nothing that prevents it in principle, and given the pace at which technology is advancing "printing a baby" may well be possible within the lifetimes of some of the people reading this.
