I believe some of the touch screen machines do print a paper tape, but it is only intended for recounts, not for the voter.
The caller to Boortz who suggested a receipt for the voter seemed to have some information on the paper trail that is generated by the machines. She herself has worked in computers for 20 years and was talking to a poll worker friend who told her about these new machines.
Before the voting starts, they run a tape on each machine to verify that all are set to zero. When the voting is over, they run another tape that shows the results for that machine, sort of like closing out a cash register at a store. My understanding is that it only shows totals for each candidate and not how one particular person voted.
