When did this start? Maybe you can buy an old printer that does not do it and get a USB adapter for it? The early HP Laserjets were fine.

- RuggedPineapple 5y agoIm not sure when it started, but I do know back in the early 90's copiers and printers were already currency aware. The copier in my elementary school wouldn't copy a dollar bill at anything close to full size, had to be at least either 75%/125%
- londons_explore 5y agoWhich raises the question... Could you copy it at 125% and then copy that copy at ~75% to end up back at the scale you started...?
- bbojan 5y agoYou sir are a hacker at heart!
- anothernewdude 5y agoNo, because you'd end up with 93.75%. You need to scale 80% to reverse 125%
- willis936 5y agoWouldn't the detection algorithm just check for "am I being asked to print currency at the correct 100% scale?"?
- sumedh 5y agoCanon copiers and printers in early 2000 could scan and print Indian Rupees, dont ask me how I know that. I assume the note needs to have the euro constellation, if its not there the copier/printer would work normally.
- nwallin 5y agoYou can go to anywhere right now and buy a b&w only laser printer and it won't have the dots. The secret tracking dots thing only works if you have yellow ink on white paper- it's hard to see. If your printer attempts to "secretly" add black dots to white paper everyone will notice.
