Thermal Printer (58mm)

Description: 

A Thermal Ink Printer is a device that is widely used at Point-Of-Sale (POS) locations to provide a printed receipt or bill to customers. 

The device works on the basic principle of applying a heated head into a special type of paper where marking is possible by heat. Thermochromic paper, or more commonly known as thermal paper, is used in this device and is widely available in small rolls that can easily be installed into the slot of the machine within a few seconds. The head of the device is hot and the movement of the head across the paper heats the coating on the paper which turns black and thus forming the letters or numbers that need to be printed. 

Technology and usage: 

The device uses a very simple technology and is widely popular for printing quickly. Used in shops, malls, supermarkets, small stores, libraries, petrol pumps, kiosks, ticket booths for local fairs,  also for utility bills by a representative who reads the water or electric meter as an example. 

The unit can be connected to a computer, laptop, hand-held device or even a smart phone with the appropriate connecting cables. 

The unit can be connected to any device that runs the following operating systems

• Windows 7
• Windows 8
• Windows 10
• Windows 2000
• Windows 2003
• Windows XP
• Linux
• Vista

Compatible with Epson or Samsung Systems.

The device also supports multiple languages, as the thermal printing device is not restricted by language or fonts.

Advantages: 

The device consumes less power, takes less space and is very light, so is very widely popular. Retail industry is the highest user of this printing technology. The speed of printing is high enough not to cause delay or waiting for the customers or users.

As there are no ribbons or ink cartridges, the expenses are minimal compared to dot matrix or inkjet printers.

Maintenance and upkeep: 

There is very minimal maintenance needed. When one roll is used up, the top door needs to be lifted open, a new roll of thermal paper dropped in, and the end of the paper pulled out and the door shut back. The printer is ready to be used again. Since there are not many moving parts (other than the printing head and a roller that pushes the paper out, the unit also lasts a long time. Just dusting the unit once in a while is all you need to do.

2. Can I use this to print bills at point of sale?

Absolutely, that is the most widely used application for this device.

3. Is the thermal printed image long-lasting?

Thermal images tend to fade over time, usually over many months and years. If you need to save a copy of the receipt for later use (ex for warranty purposes ), we suggest you take a photo or scan of the receipt and save the digital image.

4. How does the Thermal printer connect to the computer?

The thermal printer connects to the computer using a USB cable, this cable is provided with the product and comes in the box.

5. Is thermal printer worth it?

The thermal printer does not have a toner, so it is very low cost to operate. Only supplies needed is paper rolls which come cheap. This is one of the main reasons of seeing thermal printers in retail.

The process of building a perfectly flat surface or forming a 90 degree alignment requires proper measure across multiple points. Although, the level can be checked using old-fashioned tools, but they are neither easy to use, nor as accurate as laser levelling device. Older level devices take more time to use and require lot more human effort to get it right. However, with this smart laser levelling device, not only perfect levels can be ensured, but your effort can reduced to minimum.

Self-levelling laser enables the user to project laser lines on a wall while the user can comfortably perform the task. The robust design and variety of features assist users in enhancing efficiency and bringing perfection to their work.

This laser level device can project lines and dots for level guidance at long distances. The device has been designed to project both horizontal and vertical lines along with plumb point. It can be used in bright light too; the laser glasses can be used for clear visibility of the laser beam even in brightness. The device has powered option as well as battery powered so that it can be used at remote sites with ease.

The laser window has been designed with water-resistant and dust-resistant material, hence making it very useable in humid and dusty atmosphere. The device has the option to be mounted on a tripod for a higher position operation. The device provides a lot of technical features for a low price but it is very easy to use.

Digital tachometers are smart devices that enable the user to measure the speed of any motor’s shaft or any other rotating object such as the chuck of a lathe machine. The device is designed to measure the rotational speed of objects without any physical contact.

Traditional analog tachometers worked by physically contacting on revolving parts and they were comparatively harder to operate. Changing their tip according to the shaft type and holding tip onto running shaft wasn’t as easy as just directing laser light on the shaft from a distance. Laser tachometers are much safer with their no-contact feature as the user doesn’t need to make physical contact of the device with any fast-moving object like a lathe machine’s chuck. Furthermore, recording values is easier with digital display.

This product is used by lot of academic institutions and businesses in nz.

How Does a Laser Tachometer Work?

The laser tachometers emit laser light and when the light strikes on any dark surfaces, no or very less light is reflected back to the tachometer. But, when the light strikes on a bright or shiny surface, a comparatively higher level of light reflects back. The photo sensor in tachometer detects the light signal over a specific time period and accordingly measures the speed of the motor. When a piece of reflective tape is pasted on the shaft of the motor, every time the laser strikes on the tape, the tachometer counts a revolution.

Apart from taking speed readings, digital tachometers also store min/max speed readings for better performance. The test button enables the user to calibrate or practice before taking any readings.

Applications of Tachometer:

The applications of tachometers are usually related to the measurement of a motor’s speed. But they can be used for measuring the rotational speed of any object.

• In order to calibrate the speed of a motor’s speed, it is essential to measure its speed. Tachometers are widely used for calibration in the industry for monitoring the speed of motors on conveyor belts and other parts of operations.

• The speed of the lathe machine is directly affective on its performance. While working on sensitive projects, the operators check its speed and set as needed.

• Motor windings can often burn due to excessive heating or overloading. In such cases, the motors are rewound, but once rewound the RPM of the motor may no longer be the same as before. In order to measure the new RPM, tachometers can be helpful.

• Tachometers are useful in all places where the speed of a motor has to be monitored. Similarly, the speed of a generator’s shaft can give an idea of how much energy will be generated, for such details, a tachometer can be helpful. In small scale hydro generators on canals and wind turbines, the rotational speed has to be analysed for determining the power and frequency parameters.

• Industrial machinery: Monitor the speed of motors, conveyors, pumps, and other machinery

• Manufacturing: Measure the speed of lathes, drill presses, and other metalworking equipment

• HVAC: Monitor the speed of fans and blowers

• Science and research: Measure the speed of laboratory equipment such as centrifuges and electric motors

• Agriculture: Measure the speed of tractor PTO and shafts on farming equipment

• Measure the speed of robotic arms, conveyors, and other automated systems

FAQs:

1. What is the maximum range of this tachometer’s reading?

This device is capable of reading RPM up to 99999.

2. Is it useable for measuring the rotational speed of objects other than motors?

Yes, it can be used but the device may not perform well if proper conditions are not met.

3. Is it necessary to use reflective tape for measuring?

Yes, the reflective tape ensures that the laser light reflects back toward the photo sensor and the tachometer counts a revolution. However, in case of some motors, a part of the shaft is already shiny or a shiny sticker is already present for the same purpose. In that case, using a reflective tape is not necessary.
