Calculators - Printing desktop calculators

The adding machine is also known as a calculator, desk calculator with paper roll and adding machine. The calculating machine is also known as a rung wheel machine, as this used to be the mechanical drive of a calculating machine. With the desktop calculator, you can easily perform complex mathematical calculations automatically.

Calculating machines were developed to perform the basic arithmetic operations of addition, subtraction, multiplication and division quickly and efficiently.

In the early days, the machine was also known as an adding machine due to its simple function.

The calculating machine is a calculating aid that was originally invented by Wilhelm Schickard in the 17th century. Wilhelm Schickard was a German astronomer, geodesist and mathematician. At that time, however, they were mechanical machines that were only capable of addition, subtraction and multiplication.

However, Wilhelm Schickard's "calculating clock" fell into oblivion and calculating machines had to be virtually reinvented.

Today, calculating machines are known as desktop calculators with a paper roll. It's hard to imagine offices without them.

What functions do calculators have?

The range of functions of desktop calculators with a paper roll can vary greatly. Over the years, this unique invention has become increasingly mechanical and can now embed numbers, such as a calculator dictionary, in meaningful calculations and thus assist us as a tool in everyday life.

In the meantime, these special desktop calculators can also be used for complex mathematical calculations and go far beyond entering numbers or calculating round arithmetic operations.

Today's modern calculators work in a similar way to simple financial calculators or scientific calculators. Desktop calculators with a paper roll have the following functions, among others

• Non-print mode
• Profit margin calculation
• Rounding function
• Tax calculation
• Percentage counter
• Floating point calculation
• Fixed point calculation
• Multilingual text output
• Margin calculation
• Item counter
• Currency conversion
• Time
• Calendar
• Non-calculation button
• Memory protection battery

What are desktop calculators used for in the office?

The desktop calculator with paper roll can be used for many different applications. It helps to solve simple maths problems with numbers,

but the printing desktop calculator can also be used for complex calculations. Percentage calculation, currency calculation, tax calculation, square root and other mathematical operations - there are hardly any limits to the range of functions.

The desktop calculator also proves to be practical in private areas - here it is often used for tax calculations or household accounts. The printing calculator offers the advantage that the calculations can be filed directly and the application can be finalised immediately.

As you can see, the calculator has a wide range of applications. They include:

• Bookkeeping
• Tax calculation
• Price calculation
• Inventory
• Currency conversion
• Time recording
• Time calculation
• Item counting

There are also desktop calculators with a paper roll. These are useful if you want to print out the calculations, for example as receipts. Depending on the model, the printing calculators can be equipped with a cash register roll or thermal roll.

Due to its wide range of applications, the desktop calculator with paper roll is not only very popular in the office. The desktop calculator is also often used at home, at school or in many other areas.

What you need to look out for when buying a printing calculator is explained below. In any case, a calculator is a machine for all occasions.

Why a calculator and not a pocket calculator?

With a desktop calculator with a paper roll, the entire calculation process is printed. This creates a perfect cash book. This makes it easier to identify and correct any errors in the calculations.

With a pocket calculator, on the other hand, the individual calculation steps are not listed or printed out. The strengths of a pocket calculator lie in other areas.

What display do calculators have?

Calculators have an LCD display or a digitron display. The display of a desktop calculator with a paper roll usually shows between 8 and 12 numbers.

How is a calculator operated?

Both desktop calculators without a paper roll and desktop calculators with a paper roll can be powered by different power sources. Models with are available:

• Solar
• Battery
• Power supply

The most common are printing desktop calculators with a power supply. As the integrated printer is a not insignificant consumer, it is safest to use a power supply unit.

Many calculators also have an emergency battery. This also secures the entries if there is a short-term power failure and no more power is supplied to the desktop calculator with paper roll via the power supply unit.

While today's desktop calculators are powered by electricity, this was very different with the first models:

The first calculators were operated manually. Simple calculations were carried out with the help of a rung wheel. Later, the rung wheel was extended with a graduated roller. This meant that arithmetic operations, such as the transfer of tens, could also be carried out.

What printing performance do desktop calculators with a paper roll provide?

Desktop calculators with paper rolls are divided into standard models and models with an extended range of functions.

Standard models can print two to three lines per second, while the fastest desktop calculators with paper rolls can print up to ten lines per second. If you type quickly, it is an advantage if the calculator can also keep up with your printing performance . If you are not such a fast typist, a standard model with low printing performance is perfectly adequate.

What paper does the calculator print on?

The calculator prints on either thermal paper or standard paper.

Thermal paper is well suited for short-term use, for example in retail and catering. However, if the printed figures are to be stored long-term, standard paper is recommended.

Two-colour printing is possible with printing desktop calculators on both thermal paper and standard paper.

What to consider when buying desktop calculators?

Choosing the right machine for your office or school can be a challenge. In general, you should make sure that the calculator is equipped with an easy-to-use keyboard so that you can type in multi-digit numbers and combinations quickly and that it is as easy to use as possible.

A large display is also an advantage in order to display enough digits and numbers and ensure good legibility.

Furthermore, it depends on where the calculator is to be used. If you want to buy a calculator for the office, you should consider which functions are necessary.

Professional users usually need calculators that are equipped with a 12-digit display. Also look out for freely selectable decimal places and, of course, various control keys.

In private households, on the other hand, it is sufficient if the calculators are capable of basic arithmetic operations. They are usually used to process tax returns, travel planning or household accounts. In this respect, it doesn't hurt if the calculator can print and also has a currency converter and a memory function.

Is a calculator necessary in an office?

Printing desktop calculators are useful office helpers, because in many situations these calculators are quite advantageous. In this respect, you should not do without this calculator.

When buying a calculator, make sure you know exactly what it will be used for. Then you too can benefit from the advantages that the desktop calculator offers. At MAUL, you will find a wide variety of desktop calculators with a paper roll for the office. We offer various models, so it should be easy for you to choose the right calculator.
