Is the Printer on the Voting Machine the Problem?

If all of the machines were made the same, but only some of them needed to be tweaked, does it mean that they were not the same machines? That they had different settings. So I'm very curious if the ones that didn't have the right setting were in one kind of district versus another or one precinct versus another. If the vote gets printed out by the voting machine, it's the voting machine itself that's reading the, or that's the problem, right? Okay, I guess we have a whole bunch of questions. But let me make the general point. No matter what it was, the intention was everybody had the same equipment.
