With the hardware/firmware of most copiers/printers these days I don't know if they all still do it.
Most of the machines we sell/service, will print blank if you try to print "money" or scan money.
You "can" on some, scan if it is over 150% or less than 75% of the original size.
I remember back in the late 90's we had a machine at a local police department and their undercover
officers printed copies of the money for a drug bust and it locked up the machine. A "higher up" from
the manufacturer and to come with a "secret" file to unlock the machine so it would function.
We had a good laugh over that one.
