The house I grew up in had the grease pencils and the telescore "plates" for lack of a better term.  You had to wipe off the previous game markings before starting the next game.

In college, I bowled in a house that had the method I really like.  They had the grease pencils and projectors, but they gave you plastic sheets to write the scores on.  If you had a great night, you could take the sheets home with you as a memento.  I've still got mine from my highest series.  I also took the yearly award for high series in the house with that set.  It's sad to think if I were to better that achievement today, I wouldn't have the actual, original score markings for the feat.  Yeah, I guess I can ask for a printout, but it's not the same.  I have the actual score sheet used, with all of the little markings personally added by teammates/opponents as the night went on.  It's a complete document of every frame of both teams on that night.  You just can't get that kind of personality from a computer print out (if you can even get one, depending on the house you bowl in).

Back in high school when I worked at a bowling alley, I had to keep score by hand a few times when the scoring computers on a pair of lanes would break.  Partially because we didn't want to burden the league bowlers with the extra effort when it was a problem with our equipment, also because the bowlers didn't know how.  Considering the people on the teams on those pairs were all 35-60 years old (and this was back 7-8 years ago!), it was pretty surprising that NONE of them knew how to keep score by hand.

On more than one occasion, I have been in a league where the power failed and the server failed to have multiple frames backed up...nothing quite like having to start the game over from the beginning.

paper removes that problem and prevents it from occurring other than POSSIBLY the loss of the most immediate frame (although most in the pit would likely agree on what the result of the shot was).

The other thing I liked about paper was that it made practice a lot easier since you didn't have people come in mid-session and give you crap about a score on the overhead...you just marked off frames without regard to score.  With monitors, you have times where you want to put a sign out that says "I don't suck...it's called practice."
