Scanning methods are differentiated by the amount of operator manipulation needed:
- Pen or wand type readers: needs the operator to filch the pen over code
- Semi-automatic handheld readers: the operator doesn’t need to filch but it need to position the reader close to the label.
- Fix-mount readers for the purpose of automatic reading: this reading is done by passing the label over the reader.
- Reader gates for doing automatic scanning: placement of code should be under the gate for short time, letting the scanner sweep to get the code target effectively.
Here is some of the type of readers:
Pen type readers
This type of readers has a light source and a photodiode which are placed next to each other on the tip of a wand or a pen. For reading the barcode, the tip of pen swings across the bar in a stable proposition. Photodiode measures the intensity of light which is reflected back from the source of light and get to generate a waveform which is used to measure the width of bars and space in the bar code. Dark bars which is placed in the bar code is used to absorb light and the white spaces is used to reflect light so that the voltage which is created by the generation of waveform by the photodiode is an representation and pattern of space in the bar code.
The working of laser scanners is same as the working of pen type readers except the fact that they use a laser beam as the source of light and engage a reciprocating mirror or a rotating prism for scanning the laser beam back and forth across the bar code. In case of pen type readers, photodiode is used for measuring the light intensity. While in laser scanners, laser beam is used.
CCD readers take into account use of plenty of tiny light sensors which are lined up in a row in front of the reader. Every sensor measures the light intensity instantly in front of it. Every individual light sensor in the CCD reader is very minute and as there are plenty of sensors lined up in a row, a pattern of voltage which is similar to the pattern in bar code is created. The main difference between CCD reader and the pen readers and laser scanner is that CCD measures the emitted light from the bar code and pen and laser measures the reflected light frequency.
Camera based readers
The newest and the most unique type of bar code reader which is available are camera based readers. It takes into use a small video camera to take an image of a bar code. The reader then makes the use of high qualitative digital image processing techniques for decoding the bar code. This video camera uses the same technique as in the CCD bar code reader but instead of having single sensor row here it has plenty of rows of sensors for the generation of image.
Today’s time is really expensive, every single thing is costing more than you have expected. Thus its very important to find ways to save on some of the cost.

Last week Samsung unveiled its next Smartphone, Galaxy S5 officially at the Mobile World Congress. Living up to its set standards, the Korean telecom company hasn’t been shy at all about loading the phone with fantastic specs.
The wow factor of this phone is its processor which is a Quad Core Snap Dragon 805 that runs at a blazing 2.5GHz speed. Unlike the S4 model, the S5 will not come out with octo-core, at least not in the recent future. Add a RAM of 2GB to it, and you are pretty much sorted. With this speed, throw any app at it and it will run as smoothly as ever.
The Operating System:
The power packed device comes with the most recent version of android, 4.4 KitKat and newer version of TouchWiz interface.
The Samsung Galaxy S5 comes with a battery of 2800mAH which should be enough to give you backup of a day at least. Samsung assured a continuous twenty one hour of backup.
The phone will be available in two versions 16GB version and a 32GB one. The storage is expandable up to 64GB via a micro SD card. For quick transfer of data the phone comes with a 3.0 microUSB port.
The Galaxy S5 is equipped with a 5th gen Wi-Fi 802.11ac and a 4GLTE and 2X2 MiMo. An added feature of the device is the Download Booster, where both the connectivity platforms (4G and Wi-Fi) are used simultaneously to speed up your download procedure.
As far as the look is concerned the S5 matches Samsung standards of super chic, slim, light weight phones. It is expected to feature a metal body unlike its usual polycarbonate body. The back is going to be matt soft touch and dimpled all over, which looks better than the faux leather finish other higher range phone features. The phone also features IP67 waterproofing, unlike its last version. This feature prevents it from any water and dust damage. You can submerge the device for as long as half an hour without any damage to it. It will be available in different colors namely Charcoal Black, Electric Blue and Copper Gold and Shimmery White.
The device features a 2560×440 quad HD touch screen. The S5’s AMOLED screen is larger than previous version at 5.1 inches.
The camera is 16PM with LED flash, a post shot focusing feature a much improved HDR mode. The post shot focusing allows you to click 2 images as soon as you tap the shutter with differently focused backgrounds (sharply focused and defocused). The blazing .03 seconds autofocus speed of the device is worth on mention.
There are many printers available now days in the market. To choose the best among them is indeed a difficult job. The best printer that is suggested for official purposes is the laser printer. It is a multi purpose gadget which is best suited for all your needs. With the passage of time the price of the printers falls and the choices that are available increase. It must be noted here that the printers with the lowest price is not always the best one to choose. On the contrary the one which is the most expensive is of no use either.
One of the first steps that you must take before purchasing a laser printer is to set a budget. You must conduct a full fledged research and find out the average range of the printers and the features that accompanies each one of it. You must take into account the toner cartridges as they are important for determining cost printing. Color laser printers are costlier and so are the color toner cartridges.
The price of the printers may vary a lot when colored and monochrome models are taken into consideration. If you run a graphic designing or a printing company then, you may require a color laser printer. In order to produce high quality print outs the cartridges will be required in large quantities that may drain it quickly and you will have to incur more costs.
If you require laser printers for text document printing, then you must opt for a standard monochrome printer. This will require less toner and will save on some money. For the purpose of printing color documents a cheaper inject printer can be bought which need not be of a very high quality. Inject cartridges can be bought at cheaper rates and this will conveniently do your job for occasional color prints instead of buying color laser printers.
You must have an idea about the number of pages and the number of times you will be requiring the printer in a month. Slow printing can cost you less but at the same time can take around 10 seconds for the printing of one page. But if you are working in a busy office then a laser printer can do the job quickly at a slightly higher cost.
Are you planning to buy an inkjet printer off late? Well, inkjet printers are fast becoming popular especially for those in quest of a cost-effective printing solution. There are ample inkjet printers in market but if you want the best buy- here are some tips to check out.

If you are looking to print photos with your inkjet printer, check out beforehand that your chosen machine is engineered to manage the photo paper. The business users would look for duplexing function in the printer- the ability of printing on legal-size paper & envelopes.
The inkjet all-in-one printers are excellent for business houses as these are designed to carry on important office tasks like photo printing, scanning and faxing too, along with general text printing.
Make sure that the printer you are taking to comes with minimum 600 by 600 dpi in regards to text and 1200 by 600 dpi at least for photos and graphics.
Printing medium compatibility
All inkjet printers are not compatible with every print medium. Thus, if you are in frequent need of printing on different mediums, added to paper, you have to check out the printing medium capability of the device. The premier inkjet printers are engineered to suit several mediums such as variety of papers, envelopes, cardstock, vellum, labels, glossy photo-paper, transparencies, matte photo-paper & even DVDs and CDs.
