I think that helps, but only if there's a system in place to audit at least some percentage of the votes. When I voted in Mississippi, the voting machine wrote my results onto a roll of receipt paper. I have little confidence that anyone ever audited that paper.

As a sibling comment mentioned, the mere potential for auditing increases the cost for a malicious actor to perform manipulations, since the chance of getting caught is higher, and the penalty for getting caught is potentially disastrous.

While it may not have been audited, it at least has the potential to be audited, say, if there are questions regarding the validity of the outcome. That said, it would boost confidence if there some verification/auditing going on.

If you can't verify that the printed results have been counted correctly, it does not bring more guarantee. At least, the paper ballots should be kept and audited which is not the case in many States.

So instead of preparing paper ballots starting a month in advance, we try to print paper receipts for the millions of people who vote all on one night?
