5.5? Dominion used a software program called Democracy 5.5
What Ron gleaned re version 5.5 for PA is that they separated how things were handled between the printing step and the processing step.
1. User is at terminal and enters ballot, then prints the ballot.
2. Poll worker submits for processing.
It is possible that the two were not the same - the image printed as the user entered separately from that which was submitted. The inference is clear from the dictate by PA.
