Some have said that rangers have accessed the info from the field, but they certainly don't have to.
I had this same situation one year (no printer at home) and before I bought it I called and asked and the guy told me to write down the new number on my old liscense and show that to the ranger if asked. I took the guys name and said I was going to say that Ed (or whatever his name was), at the Boulder office (or wherever he was), said that this would suffice for now. The guy laughed and said that's fine, and a ranger would have to be a real ass to fine me in that situation (his words).
Not that you couldn't find a real ass,... but in my experience most rangers are pretty cool if you give them respect?
Edit: also I would probably take a pic on my phone of the compuater screen,... although I didn't think of that a few years ago,... lol Zoom in on the date and renewal and number and your name,... etc.
