I wrote one of the first internet enabled laser printers (maybe the 
first) a couple of years later. It was work -- mostly TCP -- but it 
wasn't insurmountable. v6 was pretty ho-hum if it were to become a 
requirement. That and integrating with LPR which was a shitshow. The IP 
layer was trivial in comparison.

I'm willing to believe that the networking layer was more difficult, but 
I really question about *how much* more difficult it was.
