What is the barcode printer?

Barcode printers belong to a special category of printers that facilitate printing of tags or barcode labels which can be directly attached to physical objects. They are commonly employed in labeling retail items or cartons with European Article Numbers or Universal Product Codes before shipment. Hospitals or event organizers use these barcodes for personal identification.

Why are bar-codes used?

The graphic structure of a bar code is very simple; it comprises only dark areas and light areas which humans see as the familiar "bars". These bars form a binary system of representation, in other words the barcode symbol has only two states -- "light" and "dark" --- there is no third state. The graphical simplicity means that it is very easy to place a barcode onto an object. Barcodes can cheaply and easily be printed onto many different materials. Because of this graphical simplicity it is also quite easy to create an electrical gadget that can "see" the barcode. The electronics of the gadget needs to be able to distinguish between "dark" and "light" and that is not technically difficult. Within the software of the gadget the barcode can be represented by a binary numbering system "1" and "0". Consequently it is very easy to interpret that number and convert it to the letters and digits that we humans usually read. Additionally a barcode can suffer quite a lot of damage before it becomes unreadable. The machine reading the barcode only needs to find a straight line (any straight line) between one end of the bar code and the other. That line can be diagonal. If it is possible to draw a line that crosses every bar and does not cross any smudges or gaps then the bar code can, theoretically, be read. There are many different bar code formats in use. Some of them can only represent numbers and some can also represent letters. Some barcode formats also contain extra information that can be used to check that the barcode has been read correctly. This means that if part of the barcode label is missing so that some bars are missing, the barcode read will know that what it is seeing is not a valid barcode. The machine that is reading the barcode can know immediately if it has seen a valid barcode or not. If it cannot see a valid barcode then it can immediately alert the operator of the machine so that they can correct the problem in some other way. These characteristics mean that in many situations a barcode is a very reliable way to transfer information because it is quite easy to avoid false reads and often even damaged barcode labels can still be read very easily. It is hypothetically possible to create a barcode of any length but, in practice, most barcode readers can only read quite short barcodes. Consequently barcodes are used where the information to be transferred is very simple. For example, most of the barcodes used on things that are bought in shops contain only eight, twelve or thirteen digits.

Are bar codes read optically or with a digitizing device?

Your question is a little nonsensical. let me explain.The information that makes up a barcode is visual information, therefore any process to capture information from that barcode must be retrieved optically.Secondly a digital computer requires that any information it receives to process, must be digitally encoded. Therefore any input is by default must have been digitised. barcode images, key presses, sound, all must be converted to numbers before they can be processed.There are two methods which are used to retrieve barcode data. The first is the type you see at the supermarket. This uses a laser to scan the barcode. the reflection of the laser light off the barcode produces a binary code which is sent to the CPU for processing.The other method of reading a barcode uses a camera (Digitiser) to take a picture of the barcode this picture is stored in the memory of the computer then image processing algorithms are used to distinguish the white and black bars and the code is read.So to answer your question both options are true Barcodes are read optically and digitised.

I am assuming that your question is "What is an example of an intoduction?", although it could be "How do you write an example of an introduction?", or "Is Paradise Lost an example of an introduction?" Now, to answer your question, or what I presume to be your question. What is an example of an introduction? That was.
