Results were printed out from the machines and posted outside the actual vote center after the election (Colorado law requires publishing the results of all electronic votes). If you were to visit a vote center after the polls closed, you'd see a tally report per machine on the window, visible for anyone to see.

The machines themselves were sent back and dumped. I don't actually remember if we printed 2 copies of everything (such as a copy for someone to tally up too).

In CA (Alameda County), we print out two copies - one to be posted publicly, and one to be returned to the central collection center. The collection center gets the paper printout of results, the memory card, and a printout of the system logs.
