Barcode Scanner & Barcode Printers

Barcode Printers
The bar codes originated from the Morse code. By extending the dots and dashes vertically.
At one point of time, Barcodes were put inside the packet! After that it was found to be much easier to print the codes on it instead. There has been over a hundred different types of bar codes invented. However only a half-dozen is used regularly.
A barcode printer is a machine that is designed to create barcode labels. These labels are attached to different products for various uses by small businesses and many industries as well. Mostly, two techniques are involved in the barcode printing process – direct thermal barcode printing or thermal transfer barcode printing technique.
A barcode printer creates labels for inventory, save money, increase efficiency and improve customer service. Barcode labels can be used to make checkout and inventory management easier in your retail store. Barcode printers print data formatted specifically for labeling.
Both barcode printer techniques apply heat to the label surfaces. Direct thermal printers apply heat directly to specially coated labels, which causes the paper to turn black. While a thermal transfer barcode printer applies heat to a ribbon, which melts a waxy resin substance on a ribbon. This substance is then transferred from the ribbon to the label.
Barcode printers are available in different varieties with different features. If you are a product-based company, you would need barcodes. Instead of using a third party to print the labels, it is always better to own a barcode printer.
Exclusive printers for barcodes are introduced in market with various compatibilities and features. Getting a compatible barcode printer for your business is never a complicated deal.

There are four basic types of barcode label printers: Ink Jet, Dot Matrix, Laser, and Thermal.
A barcode’s readability, or scan ability, depends on its print quality. Dot matrix printers create poor quality barcodes that can be difficult to scan. Dot matrix printers are also limited in print speed and size. They tend to be slow in printing and cannot print small barcodes. Laser and inkjet printers have great print quality, but they must print the barcode as an image, which uses more memory and slows down the print speed. Laser and inkjet printers must print an entire sheet of labels, instead of one at a time. They also have a very limited array of label face stocks on which they can print. Thermal barcode printers can print high quality text and graphics as well as barcodes. The barcode fonts reside in the thermal printer, so it will not slow down the print speed, which can get up to 12 inches per second. Thermal printers can print any number of labels from one at a time up to an entire roll. They can also print very small, high-density barcodes and can print on a wide variety of label sizes and face stocks.
Thermal barcode printers work by essentially using controlled heat to create an image onto the media. There are two thermal print technologies: direct thermal and thermal transfer.
In direct thermal printing the print head applies heat to coated thermal media (labels or tags), which turns dark where the heat was applied. There is no ink or toner consumable – the only supply needed is the direct thermal material. In contrast, for thermal-transfer printing, the print head heats a ribbon, which transfers wax or resin to the media.
Thermal barcode printers come in a variety of form factors: desktop, mid-range, industrial, and portable. One of the biggest factors to determine which barcode printer to select is the number of labels that are going to be printed daily.
Mid-range, or light industrial, barcode printers can handle a wide variety of media sizes, from very small serial barcode labels on cell phone components to very large chemical drum barcode labels. They can also handle a wide variety of media types, from basic paper barcode labels to synthetic barcode labels that are flexible enough to wrap around a vial or durable enough to withstand extreme weather conditions outdoors. Mid-range barcode printers are designed to print about a 1000 paper or synthetic labels a day. With faster processors and built-in memory, light industrial barcode printers are able to handle more complex barcode label designs quicker than a desktop barcode printer An industrial barcode printer is a device designed to print barcodes on labels or products.
Barcode printers usually come in the form of desktop label printers. They have interfaces through which specific information can be supplied, such as batch numbers for a production run or other details from a database.
Industrial barcode printers often have feature’s that standard computer printers do not support. For example, industrial barcode printers have automatic numerators that will ensure that a predefined higher or lower number in the required sequence is printed on each label.
Industrial barcode printers also have a date offset option that is of particular use to the packaging industry. This automatically moves the date forward from the current date by a specified number of days during printing so that the best before date can be automatically printed.

Barcode Scanner
A barcode reader is a scanner capable of reading barcodes by means of a laser or imager area reader. It is an electronic device whose main function is to scan these codes and send the data, via a Wi-Fi antenna, Bluetooth or cable, to a handheld or computer that will manage and store the information obtained from the readings taken.
It is an essential device in sectors such as industry, retail or logistics, in short, in any business that has a warehouse or shop. Where you can’t afford mistakes that cause you to lose customers, slow down work or mismanage labelling or inventory. You need a barcode reader that is agile, that allows you to read at the distance you need, that reads different types of codes, that is robust. In other words, a reader capable of working smoothly, whatever the application or environment.
Barcode scanners are categorized based on their functionality and form factor including: handheld barcode scanner guns, 2D barcode scanners, corded, cordless, presentation, barcode scanners with keypad, mobile computers, in-counter, wearable, sled, and fixed mount. Each form factor offers advantages and features designed for specific environments, applications, and industries. Available in various configurations, industrial barcode scanners are ideally suited for a wide variety of industries and applications around the world such as retail, healthcare, manufacturing, grocery, and postal delivery services.
The device consists of a light source, a lens and a light sensor translating optical impulses into electrical ones.
Barcodes, also known a universal product codes (UPCs), are machine-readable data representations made up of bars of dark and light areas which represent a set of data, often a string of numbers. These codes are printed by a standard printer onto a label or other visible surface.
Reading a barcode involves a method to detect the code and transform it into a digital representation. The most common method uses light that is aimed onto one part of the code at a time and detected by a light sensor that reads the reflected light.
A dark area will not reflect as much light as a light-colored area. The difference is detected with the sensor and sent to the computer. The code is determined by the thickness and spacing of the dark and light areas. A very basic barcode scanner uses a single LED light and light sensor. In this case, the user would need to slide the reader directly over the code.
More advanced readers use a laser beam that is automatically scanned over the code with a rotating mirror to illuminate one part of the code at a time. Other methods include a camera to see the code which is interpreted into the corresponding light and dark areas.
Each scanner type has its own advantages and disadvantages. The best type of barcode reader is one that’s best suited for the barcoding system followed, the working environment, the required reading range, the total cost of ownership, and other key characteristics.
That’s why it’s wise to consult with an expert like Barcoding when evaluating the choices. At Aslink Computers our Process, People, Technology (PPT) philosophy focuses on workflows and the people performing the tasks before making technology, system, or device recommendations.
1D and 2D Barcodes
While early barcodes were simple one-dimensional symbols, many modern barcode systems use two dimensional shapes like squares or dots. These 2D barcodes, such as QR codes and a number of industry-specific standards, can hold much more information per unit area than linear 1D codes. While 2 D scanners can read both 1D and 2D codes, 1D scanners can only read linear codes. For settings which require 2D codes, or might utilize them in the future, make sure to purchase 2D scanners.
Today there are many types of stationary and mobile scanners, the ones we will discuss are laser scanners, image scanners, 2D area imagers, CCD barcode scanners, and pen readers/barcode wands.
following barcode scanner buying guide to determine which type and format would make the best barcode scanner for your retail store or operation:
Laser Scanners
The laser scanner is one of the more high-tech tools for barcode reading. In scanners of this type, the laser serves as a light that reflects through a series of mirrors or prisms that read the barcode
Laser scanners are designed to read linear 1D barcodes and can read anywhere from six inches to two feet away. As such, laser scanners consist of multiple internal glass or plastic parts that move with each scan — making the laser scanner more vulnerable to breakage than an image scanner. Aside from the laser factor, barcode scanners of this type function in a similar manner to pen readers.
Wireless Barcode Scanner
If you need added mobility when scanning, a wireless scanner may be right for you. These barcode scanners use Bluetooth or RF radios to send data to a communications cradle connected to your computer, allowing you to travel up to three hundred feet from your computer to scan barcodes. Bluetooth models have the added bonus of compatibility with Bluetooth-compatible mobile computers, laptops, or smartphones, giving you greater mobility.
Scanner / Scale Combination
Commonly seen in grocery stores and hardware stores, combination scanner / scale devices give you a mix of fast omni-directional barcode scanning and weighing of products. These are a great space-saving solution if you sell products by barcode as well as weight. Although more expensive than other scanners, a scanner / scale combination provides tremendous durability and longevity, maximizing your return on investment.
Wand Barcode Scanners
Wand scanners, also known as barcode wands or pen scanners, use a light source and sensor embedded in the end of a pen-like instrument. This wand is dragged over the barcode at an even speed, and the reflection from the light is measured to read the barcode. Pen-style readers are simple and inexpensive, making them perfect for small scale settings. However, they are typically slower than other technologies, and are sensitive to user error.
Industrial Scanners
Some handheld scanners are made with increased durability and ruggedness, perfect for industrial uses. Many of these units are shock and water resistant, and some are dust or contaminant proof, making them suitable for outdoor use. Industrial scanners are usually distinguished by their yellow or red cases, rubber housing, and larger size.
