Okidata is one of the few printer manufacturers that doesn't print the printers info within the page it prints (via a series of unique dots / pixels that can be forensically traced, not seen with naked eye). These are the specific printers that dominion suggests governments buy for use with their system that allows ballots to be printed "anywhere". (scroll to "mobile ballot printing", DL brochure https://www.dominionvoting.com/optional-solutions/). It's a bit ironic that the only large brand that doesn't print the forensic fingerprint of the printer on the ballot is the exact brand that dominion pushes. Can't make this stuff up!
