Difference between Impact and Non-Impact Printers
A printer is a device that prints data or computer outputs onto paper. Printers are split into two types based on the technology used: impact printers and non-impact printers. The major distinction between these printers is that impact printers produce images using an electromechanical impact mechanism. In contrast, non-impact printers do not employ a mechanical impact device.
In this article, you will learn the difference between Impact and Non-impact printers. But before discussing the differences, you must know about Impact and Non-impact printers with their advantages and disadvantages.
What are Impact Printers?
Impact printers utilize an electromechanical component that impacts on the paper to print the letters on the paper sheet. It is comparable to a mechanical typewriter. The mechanism employed in these printers is referred to as an electro-mechanical mechanism. It operates at a slower speed than non-impact printers because of the use of a mechanical component.
Types of Impact Printers
There are various types of impact printers. Some important types of impact printers are as follows:
1. Dot matrix printer
Dot matrix printers generate images by hammering a grid of pins against a ribbon. Different pin combinations are utilized to print several characters.
2. Drum Printer
The paper in a drum printer is attached to the drum for exact alignment to the nozzles. When the required character for the specified location is rotated around to the hammer line, the hammer hits the paper from behind and pushes it into the type slug when it is rotated around to the right position.
3. all Printer
A spherical ball with raised characters on the outside is used in ball printers. Before printing on the page, the ball spins to every character.
4. Daily wheel printer
These printers are connected to a daisy wheel containing all the characters required in the printing process. The characters are carved on little metal plates that are put over a wheel spoke. While printing, the wheel turns at high speed, and an electromechanical hammer strikes the appropriate character when it reaches beneath the hammer.
It impacts the character on an ink ribbon, causing the ink on the ribbon to bleed and leaving an impression of the character's shape on the paper. The replacement of a wheel may result in each wheel printing a distinct set of characters. Daisy wheel printers are rapid and suitable for printing elementary text, with speeds ranging from 10 to 50 characters per second. However, these may not be utilized to print photos.
5. Line Printer
It is a high-speed printer that may print a full line at once. A high-speed line printer can produce up to 3,000 lines per minute. Line printers have the disadvantage of being unable to produce graphics, having poor print quality, and being quite noisy.
6. Chain Printer
It's the printer for characters. A chain printer's print element is a metallic band or chain with embossed characters that spins horizontally in front of the paper. A complete chain is made up of five pieces, each of which has 48 characters. As the print chain rotates, appropriately timed print hammers impact the paper and the inked ribbon against the appropriate character on the chain. Chain printers are among the quickest impact printers, producing 400 to 2500 letters per second. Characters on a rotating band are utilized in chain printers, also known as band printers. These devices may be capable of speeds of up to 3000 lines per minute.
Advantages and Disadvantages of Impact Printer
There are various advantages and disadvantages of impact printers. Some important advantages and disadvantages of impact printers are as follows:
What are Non-Impact Printers?
Non-Impact Printers make no direct contact between the paper and the ink ribbon. They employ laser, xerographic, electrostatic, chemical, or inkjet printing technologies. These are quieter and do not need mechanical moving parts to print. These printers create images and characters without physical contact between the paper and the printing device. Printing is accomplished by depositing ink on any type of paper.
Non-impact printers can print numerous pages per minute at high speed and with a low noise level. These printers have very low or negligible noise levels because they do not use a striking mechanism in which the printing head contacts the ribbon and paper. Instead, they use a completely silent process of depositing ink or toner onto the paper.
Non-impact printers print graphics and characters onto paper using a laser, a spray of special ink, or heat and pressure. The print quality of a non-impact printer is better than that of an impact printer. Toner (dry ink) or liquid ink cartridges are used in these printers to print on paper. These printers utilize the latest printing technologies, and they are more costly than other printers.
Types of Non-Impact Printers
There are various types of non-impact printers. Some important types of non-impact printers are as follows:
1. Laser Printer
A laser printer that utilizes electrostatically charged areas on a photosensitive drum to attract toner (or dry ink powder) to generate significant printing material. A heating process transfers the toner to a piece of paper and glues it together.
A plotter is comparable to an inkjet printer. However, it is useful for printing on larger-sized paper rather than standard paper. These are mostly utilized for setting out and printing engineering drawings such as building plans, mechanical component drawings, assembly drawings, etc.
It may print both colour and black and white documents. Drum plotters and flat-bed plotters are the two types of plotters. Drum plotters roll the paper over the drum. On the other hand, a flat-bed plotter employs plotting pens over which the paper is positioned.
3. Inkjet Printer
The mechanism of an inkjet printer differs greatly from that of an impact printer in that it ejects minuscule drops of ink via small ink nozzles in the print head. It employs a resistive heating effect to heat each nozzle in microseconds selectively. Its heating action aids in the expansion of ink in the cartridge and nozzle ejection onto the paper.
The ink from the nozzle generates small dots, which combine to form characters or images. The instructor specifies the movement of the cartridge using the printer, and it normally advances sideways. A roller was used to roll the paper for the printer to produce the next line.
4. Thermal Printer
The output characters of thermal printers are generated by a specific heating element that is combined with special heat-sensitive waxy paper, which forms darkened dots when the element reaches a threshold temperature.
Advantages and Disadvantages of Non-Impact Printer
There are various advantages and disadvantages of non-impact printers. Some important advantages and disadvantages of non-impact printers are as follows:
Key Differences between the Impact and Non-Impact Printers
Here, you will learn the various key differences between impact and non-impact printers. Various differences between impact and non-impact printers are as follows:
Head-to-head comparison between Impact and Non-Impact Printers
Here, you will learn the head-to-head comparisons between impact and non-impact printers. The main differences between impact and non-impact printers are as follows:
Both kinds of printers have advantages and downsides. According to the above analysis, it is very clear that non-impact printers are more accurate and cost-effective than impact printers. Impact printers are the standard method of printers that may not print multiple copies of a document and be utilized for basic printing. On the other hand, non-impact printers are new printers built to improve regular printers' features. These can make duplicates of a document.
