When printing checks, it's always best to use MICR toner in a MICR printer. We don't recommend ever using standard toner or a standard printer. Why? Because meeting ANSI standards is important. It shows that you have done your due diligence to prevent fraud, which could protect you from liability later.

While the MICR font is clearly visible on every paper check processed today, that wasn’t always the case. Prior to the mid-1940s, checks were processed manually. As the number of checks increased, finding an automated way to process them became essential.
