Casio Inc. HR-100TM Business Calculator

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.

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.

This calculator is excellent for ordinary math tasks. You do not have to install or seat the inker--it comes installed--so please disregard the first 3 star review that was obviously based on an earlier version. It's extremely easy to set up and operate: just remove it from the box, insert the tape-roller holders, place the tape in it, push the edge of the tape through the slat in the rear of the machine, connect the plug to the machine and to an electrical outlet or use it with batteries, push the start button on the calculator, and its ready to perform numerous functions--very easily. All subtractions are printed in red ink, everything else is in black. I did not read the manual because I knew how to do all the tasks I needed to perform, having had a similar Casio machine in the past. But it shouldn't take but a few minutes to figure out how to use the functions by trying each one alone or in conjunction with some of the other functions. It's well worth the $ 20.00 I paid for a new one. It also has a 1 year warranty. You can COUNT on it.

I purchased this calculator specifically for the printing function and after only 4 months of use this function stopped working. I pressed the reset button, but the printing function still did not work. I decided to remove the batteries to do a full reset of the calculator. Since I had the batteries removed, I went ahead and replaced them even though the display was working. After doing this, the printing function started working again on the calculator and it seems to be working fine now. (Also to note: I was using off brand batteries and replaced with Energizer batteries. Not sure if that was a factor in the problem.) I am a bookkeeper and I need the print function primarily for long adding calculations. Overall, the calculator size is good. It doesn't take up too much work space, and the keys are large enough for easy quick calculating. The keys are a good size and spaced apart well for three finger (plus thumb) accurate calculating . The display numbers are bold and easy to read without needing a lit display. Good overall performance.

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.

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.

I had one little hiccup while using this. It would not stay running, it kept shutting off. I unplugged it, and moved it to another location, and it worked perfectly, hasn't given me another issue. I'm going to assume that the plug was loose, or some other user error. It works great for someone who needs an adding machine on occasion. If you need this for heavy use, perhaps this isn't for you. For my needs, which is once or twice per month, it works spectacularly. The ink is a very small cartridge. It has print on it instructing the user how to remove it. At first I assumed it was a clip to keep the printer head from moving during transport, so I removed it. Needless to say, it didn't print well without it. Just something to be aware of.

It's a calculator with a printer. It's easy to use. Most of us have seen them before. this one does math, which I like. It has a printer on it so I can check its work, but if I wanted to do that, I wouldn't be using a calculator. It comes with instructions, but let's be honest. If you don't know what a specific symbol stands for, You won't be using that function. You're more of a add/subtract user. I am too, it's cool. It comes with a power cord so you can plug it in, and has a "aa" battery port so you can take it camping. it is not water proof, so when you do take it camping, be careful, and make extra sure not to use it while canoeing. the buttons go all the way down, and come all the way up (unless you spilled soda all over it.) the screen displays Arabic numerals, sorry Romans. It's a calculator with a printer. it's pretty good.

Es rápida, práctica y ligera. No es ni grande ni chica. El tamaño perfecto para usarse sin microscopio ni para que robe medio escritorio. Me encantó la calidad de la sumadora, el precio y sobretodo que es muy ligera y sólida. Yo la uso con pilas y me olvido del cable. Lo único que no me gusta es que no se auto apaga, tampoco es para quitarle una estrella completa. Fuera de eso es perfecta. Sin duda un producto de mucha calidad. La recomiendo mucho.

Excellent.

After a couple of decades of use, my old adding machine finally died. I wasn't looking forward to getting a new one and figuring out how it worked. But this Casio calculator is great! Easy to use. Can be plugged in or battery operated, which is very handy. It also has more functions on it than I'll ever use, but good to have in case. I highly recommend this calculator to anyone who's looking for something a little more substantial than a hand held calculator.

大きくて使いやすく、プリンターで印字され、マイナスは赤で印字されるので、後の計算ミスの有無も確認出来るので、非常に便利です。税金も計算でき、他にも色々ファクションキーがあり、便利です！

I love how fast it is. Could have a LOT better instruction manual. Once you figure it out though it is a great little machine. I would recommend it.
