Printing paper is cheap. Shipping it is cheap. Checking it is cheap and obvious. Reprinting is cheap. You don't even need to ship them. Most of the cities are close to industrial areas which has big printers and paper mills.
Making stamps or buying pens is cheap. You validate ballots at the polling stations which is scalable and cheap. It is the members of public who validate it. You don't need to pay most of them. They are just local constituents! It is their vote!
You are not aware how far away you are from the point!
They're not involved in the tally. Merely displaying and printing a ballot. Which will be verified by the voter. You actually need /less/ security.

Correctly managing it's physical distribution is not. We have thousands of poll locations. What if the wrong ballots get used? What if a location didn't get the update delivery? Should we just close it? Use unofficial ballots? Write everything in?
Electronic distribution of ballots solves these very real issues. Please, take some time, and search for common polling location problems and their impacts. You're acting as if they've never happened.

Right. So when the machine _prints_ my ballot then _I_ validate it. We're just moving the same amount of work to a different entity. The one that actually cares that the work is done correctly.

I don't believe you're actually seeing the point I made correctly.
