Monroe UltimateX Heavy-Duty 12-Digit Programmable Accounting Printing Calculator

Our engineers at Monroe worked tirelessly to develop the best available printing calculator on the market. The Monroe UltimateX combines all of the favorite features from previous Monroe models and is the top-of-the-line 12-digit print/display heavy-duty calculator. As a result, the Monroe UltimateX is the preferred printing calculator by accountants. The Monroe UltimateX features our newly updated printer which, for the first time in Monroe history, is compatible with universal supplies such as the Monroe P65M ribbon spools, or you can use our exclusive Monroe M33X ribbon cartridges and our signature 20 lb. paper tape rolls. Using our high-quality Monroe supplies will provide you with the optimal print quality.

Key Features

  • Velvet touch keys with individual key switch technology - our keys are more sensitive to touch than any other printing calculator brand, you will feel the difference
  • Ability to edit and reprint the audit trail paper tapes for up to 99 entry lines
  • Print speed of 5 lines per second
  • Select running subtotal or grand total on your display screen
  • Enclosed paper roll to protect from dust build up (read our blog on the enclosed paper roll)
  • Red LED indicator to make users aware of an active calculation that has not been totaled yet
  • When you press the total key, the total will automatically print and advance above the tear-off off knife so you do not need to worry about advancing the paper roll manually. We even provide the option to turn that feature off in case you would prefer to save paper.
  • Hidden storage compartment for a spare paper roll and a twin-spooled ribbon to reduce downtime or the need to leave the calculator to retrieve supplies
  • (2) 4-key independent memories that will allow users to simultaneously run multiple math problems, all while having the ability to store their respective tax rates
  • Independent operation of multiplication and division, which enables users to multiply and divide without interfering with their addition and subtraction totals.
  • Inspired by two of our most popular calculator models ever - The Monroe Pro and the Monroe Classic

Those who know, choose Monroe.

    This is an amazing calculator

    Posted by Jon on Aug 3rd 2019

    I cannot believe how great this works. One of my colleagues raves about this, so when my Sharp calculator died I figured I would try this brand. Coming from using a Sharp calculator I had to adjust to the total key being on the other side, which only took about a day. The functions on this are far more advanced than I expected. I love love love the edit feature! And they even thought of a storage compartment for an extra paper roll! I’m impressed and happy that I switched to this.

    Monroe's are the best

    Posted by Theresa on Nov 15th 2017

    My first Monroe was a Monromatic that my Dad bought for me (that's when I started collecting typewriters & adding machines). I have always wanted a new Monroe & I finally splurged & bought one for myself & I'm so glad I did. I love it!!!!! Monroe's are the best

    Why didn't i purchase the ultimatex earlier?

    Posted by Christian thompson on Jul 14th 2017

    I recently had to replace my office Casio DR-T220 printing calculator, due to the display going dim and not readable. After researching and recommendations from other accountants, I was hesitant to purchase the UltimateX due to the price. After researching this model and the history of Monroe, I knew this was the best purchase decision . When the UltimateX arrived and began using it, Even the display is larger and cleaner. I was mad at myself for not buying or considering Monroe years ago. I decided to buy two more to replace the ones for my home office and remote office location. Even though the key layout and function on the UltimateX is different from the Casio's and going to take a while to relearn, I am not choosing anything else but Monroe. It is worth it. Their customer service has been outstanding and an absolute positive experience.
