Review: Perfect for work or personal use...highly recommend - UPDATED REVIEW 5 Years later: Okay, it started malfunctioning this past Summer so it lasted about 4 1/2 years...the previous calculator (exact same one) lasted 20 years...so like everything else, price has increased...quality has decreased! I purchased this exact same one again because I am so familiar with the functions & it just "fits" me. I bought my new one just last night at a big box store (can't give name here, but you know the one--the most popular big box store begins with a W) The items cost a tiny bit less than $35. So, I'd recommend looking around before ordering...at least at $35, when I throw it in the trash it won't feel so bad. It is a great calculator, you'll love using it-it's easy to use, easy to read & the printout helps a lot if you're balancing several items. It is well worth $35! I wished I'd waited, every time I look, the price has dropped...very good deal! I've used the CASIO calculator (exact one, except color) for at least 20 years with absolutely no problems. I love the large number keys and large display screen. The only reason I bought this one, is because while working a few days ago...I spilled a Pepsi into mine and even after washing, the keys still stick, so I ordered this replacement. Other reviews stated that it came with batteries...it does not. It does require 4 AA batteries and it does come with a power cord and a small amount of printer paper, very small amount...just enough to give you the idea and the paper is easy to load and replacements are easy to find. Tip: when changing paper, I always attach just a small amount of clear tape joining the new roll to the old roll and then just press the FEED button...easy! Just in case you didn't already know that...hope to help! UPDATED REVIEW 5/24/2023...I needed another good calculator, so I came to order this again and WOW! There has been a major price increase. This is no longer a good deal. The price has increased by about 75%. I recommend either another seller or another item. It's simply not worth what they are charging now. Review: UPDATED REVIEW! So far it has worked beautifully. The printout is clear - 5 years later and this thing is still going strong! Had to replace the ink tabs ONCE in 5 years- I use this thing DAILY and always have it set to print. Despite the battery issue, I’m giving it 5 stars. Would definitely buy again, but frankly that might not be necessary for several more years!! Purchased this calculator to replace my old one, which I had for about 25 years. The ONLY reason I had to do that is because the old one (which was a Texas Instrument) digital screen was no longer working so the numbers were disjointed and I could no longer read the display. So I scrolled through hundreds of reviews and questions to find the right one and finally settled on this one. So far it has worked beautifully. The printout is clear, the display is clear, everything works BEAUTIFULLY to it totally fit my needs. The only reason I gave it 4 stars instead of 5 is because it sucks when it is on battery power. My old calculator ran off of batteries (it had an AC adapter but I never used it). The batteries in that old calculator would last YEARS- LITERAL YEARS. And it didn't matter what brand- Energizer, Duracell, storebrand, you name it. Any standard AA batteries lasted a MINIMUM of 5 years in that old calculator. So that was the main reason I wanted this Casio was so that I did not have to have it tied to an AC cord indefinitely. Yeah...well that is not working out so well. I put batteries in it and it worked on them for about 2 weeks....I went through about 4 sets of batteries in about two months until I finally decided to leave it plugged in all of the time. But there was a time when not being able to run this off of battery power would have been cause for me to return it. So if you are planning to use this PRIMARILY on battery power- find a different calculator. If you don't mind leaving it plugged in all of the time- YES, buy it. ## Features - Printing calculator - 2 line/second - 12 digit LCD display ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #256,762 in Office Products ( See Top 100 in Office Products ) #77 in Printing Calculators | | Customer Reviews | 4.5 out of 5 stars 3,870 Reviews | ## Images ![Casio Inc.

The 9% tax rate is stored Credit:: I copied some instruction from (Eduardo Hiroshi Tanaka Nakagaw) **Q: what type of paper is used?** A: Regular paper rolls. This in not a thermal printer. **Q: What replacement ink cartridges does it take?** A: What replacement ink cartridges does it take? **Q: Does this print date and time?** A: This calculator can print the date or time when entered manually. To print the date, say for example, October 25, 2019, you would enter 10.25.2019 followed by the diamond/number key. To print the time, say for example, 9:46 a.m., you would enter 9.46 followed by the diamond/number key. If you need to print the date repeatedly, I recommend saving it to the memory using the M+ key. Each time you need to print the date, press the M diamond key followed by the diamond/number key. At the end of the day, press the M* key followed by the CA key. This clears the date from the memory. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for work or personal use...highly recommend *by H***S on March 1, 2017* UPDATED REVIEW 5 Years later: Okay, it started malfunctioning this past Summer so it lasted about 4 1/2 years...the previous calculator (exact same one) lasted 20 years...so like everything else, price has increased...quality has decreased!

Top-notch value. *by B***Y on April 20, 2018* Clear, well made, capable calculator. I used my late Dad's 1960 Texas Instruments AC/DC calculator until it refused to "take" or advance the paper roll. I might add that in 1960 a simple calculator was enormously expensive- - after almost 60 years of service, I figured it was time for a new one. I read some of the reviews of this unit. and just shake my head at some of the negatives. Everything about this calculator is just fine. For myself and my needs, it fulfills every last requirement -- and yes, I have utterly no idea what 90% of the functions do. . .:)! And, I don't need to. Like most folks I use the unit to balance a checkbook, add up some tax deductions, and do a "percent" here-and-there when trying to price compare things I'm interested in buying. I bought some additional paper rolls, and some ink cartridges (the Texas Instruments calculator used the "chemical reactive" paper, which was fine, but did not print nearly as dark or clear as this unit). Everything ran me less than $40! And people complain? Buy it! It'll do what you need it to do. End of story. ## Frequently Bought Together - Casio Inc.
