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.
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.

**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.

### ⭐⭐⭐⭐⭐ Going to buy more...very happy.
*by H***B on October 29, 2018*

I buy and/or not purchase items based on the reviews I read.....so I am cautious about giving a detailed review. With this purchase.....I have to say....extremely happy. Great office/desktop calculator. Easy to use....love the size (not too bulky) The word "mini" had me hesitate....because I don't like tiny calculators. But this is definitely not "mini"....just a perfect size...smaller than those bulky machines that take up half your desk....but like a regular larger calculator. Numbers and keys are large enough to work quickly......and the screen is clearly visible even under strong retail-store lighting. I was using a basic calculator we had purchased from an office retailer and one thing that I didnt like about that one was the auto shut-off. (Example: I would run 9 items and add them up.....if I stepped away for a moment.....I would come back to a blank deleted screen because most calculators have an auto shut off). The number would be gone and you have to start again..... So happy with this Casio....even after an hour.....the number you left on the screen is still there. Comfortable size keys allow you to work quickly......and the screen is very clear. Also runs on battery or electric....plug was included. Very happy.....definitely going to buy more for my stores.
