For owners of laser printers or copiers who have been shopping around for the best prices and selection of toner, you know that there is a lot of terminology to learn. One term you will bump into when shopping for toner is MICR. The acronym "MICR" stands for Magnetic Ink Character Recognition. MICR is a process by which documents are printed using magnetic ink and special fonts to create machine readable information for quick document processing.
The main purpose of MICR toner is to print accounting and routing information on bank checks and other negotiable documents. MICR toner has been in use for a long time by banks and other institutions because it is often very difficult to counterfeit. Chances are that if you are shopping for toner for a home or office printer, you can pass right by the MICR toner choices on the shelves.
