Monroe 8130X Heavy-Duty Printing Calculator

The standard for heavy-duty desktop printing calculators, the Monroe 8130X serves as the entry-level, heavy-duty model with one of the strongest followings. This model is popular within casino cages and supermarket chains because of its ability to run 24/7 without failure and because it outlasts and outperforms any other competing model available. The Monroe 8130X features our newly updated printer which, for the first time in Monroe history, is compatible with supplies such as the Monroe M33X ribbon cartridges, Monroe P65M ribbon spools and our signature 15 lb. or 20 lb. paper rolls. Using our high-quality Monroe supplies will provide you with the optimal print quality.

Key Features

  • Print speed of 5 lines per second
  • Slide switch to select running subtotal or grand total
  • Enclosed paper roll to protect from dust build up (read our blog on the enclosed paper roll)
  • Indicator lamp (making users aware of an active calculation)
  • Automatic total print above tear-off knife
  • Hidden storage compartment for a spare paper roll and a twin-spooled ribbon to reduce downtime
  • Independent operation of multiplication and division capability, enabling the user to multiply and divide during addition and subtraction

    Best Calculator

    I've worked in the accounting field for over 30 years. Started with a Monroe calculator and will never switch. By far, the best machine on the market.

    A workhorse

    I just purchased this model after having my last Monroe for over 15 years. This is noticeably better than my previous Monroe. I’m glad to know that you guys are still producing the best calculator products out there
