How to choose a scanner

Before buying a scanner, you need to think about what exactly you need it for. Will you scan photos, digitize old archives from photographic film? Or are you going to digitalize texts from books? Or maybe you're even looking for an office scanner to process a lot of single-page documents every day?First of all: do you even need a scanner as such? If it's a rare task for you to enter images into a computer, you probably shouldn't shoulder the cost of buying a specialized device. A digital camera can handle a small amount of this work quite well, just aim it properly. The advantage of this technique is that it is not bound to the size of the surface. And even with a classic scanner, this feature can be useful. You won't be able to fit a large-format book into an A4 scanner, but you can easily photograph it.Another option for those who rarely need a scanner is the so-called MFP. This abbreviation means "Multifunctional device". A printer combined with a scanner can serve as both, and even be used as a copier. If the scanner for you is only an "appendage" to the printer, which is needed much more often, then the choice should be made based on the characteristics of the printer part of the combine.There are three main types of scanners - a broach scanner, a flatbed scanner, and a slide scanner. However, an extended scanner is not always convenient, you can put only one piece of paper in it, not attached to anything. In other words, you won't be able to scan a book or paperclip-bound documents. There may be a place for such a device in the office, but for the vast majority of home users, the choice will be only between a tablet and a slide scanner. A slide scanner is a specialized device and not everyone needs it. If you are willing to put up with some reduction in quality, you can also purchase a flatbed scanner with a slide scanning attachment. However, even it is needed only by those who deal with film frames, and they are becoming increasingly rare. The conclusion is that, as a rule, a tablet scanner is better for home use.The extended scanner has one rather specific advantage. It makes it easier to scan long documents - in the sense that they have a format different from the classic ruler A. Some kind of elongated banner, teletype tape, etc. If you are working with non-standard paper media, then you may really need an extended scanner.Office workers who often scan not books or albums, but sheets of documents, and even in large numbers, will find a device for automatic page feed useful. They are equipped with both flatbed and extended scanners. The larger the daily scan volume, the more sense such an addition makes. Accordingly, if you turn on the scanner rarely and for a short time, it is of little use.The maximum size of the scanned page is very important. As a rule, the user needs either an A4 or a larger A3 scanner. There are more units, but these are usually expensive equipment needed by copy centers and other similar institutions. You don't need it at home or at work. After all, if you need to scan A2 once or twice in your life, you can contact an outside organization somewhere. Alternatively, bend the document in half, if it's some kind of card, scan the A3 twice and connect the two pieces of the picture already in the computer, in a file.Unfortunately, the A3 scanner takes up a lot of space, it is bulky and inconvenient in everyday life. It won't even fit on every computer desk. You need your own bedside table for this device! The smaller your apartment or office, the more sense it makes for a small, more compact A4 scanner. In general, proceed from three important points. Needs and finances, as well as the size of the room. And choose between these two formats.Most scanners for home and office have a resolution of 600 to 1200 DPI. I mean, dots per inch. If you work with images professionally, you will have to buy a more powerful device with a higher resolution. It costs more, but the scan quality will be much higher. However, by default, such scanners create very large and bulky image files. They can take up a lot of space, and they will "take a long time to turn over" on a slow computer.In general, the home user, as a rule, does not particularly need this power. Unless, of course, we are talking about a home-based designer. All the rest are 1200 dpi, in most cases a decent resolution.It's the same with color depth. For most ordinary users, 24 bits are enough, while professionals need more - perhaps even 48.Just in case, let's remind you about an elementary thing. Any modern scanner must be equipped with a USB interface! In a new hardware store, you are unlikely to find a device without this option. However, if you choose a scanner somewhere in a thrift store, think about it. If it is not equipped with a USB interface, it means that you have unearthed such decrepit junk that it is valuable only as an antique. And that's unlikely.But not all devices have the option of powering via a USB cable, and besides, it makes the device more expensive to some extent. But sometimes the opportunity not to mess with the wires from the outlet can be very valuable, especially if all the extension cords in the apartment are always busy. And with this option, you can use the scanner by powering it from your laptop if the electricity is turned off at home. But then keep an eye on the battery level of the laptop!It is also sometimes recommended to check whether the scanner is compatible with your operating system. Win, Mac, Linux? If you buy a device from a well-known company, such as, say, HP, you will most likely have compatibility. However, in any case, it doesn't hurt to check - the list of operating systems with which the scanner is compatible is usually listed somewhere on its box. But you can ignore the set of additional programs.They are not the value of the scanner! If you are not satisfied with something, you can always search the Web for free programs with the necessary functionality. In addition, the latest versions of Windows have built-in programs for working with the scanner, which are usually enough for home users. And professionals will still have to purchase additional programs separately. For them, what comes with the scanner is a cheap half-measure.And finally, one more piece of advice. If you are not very well versed in computer technology, and you need the advice of a sales consultant. It's better to go to a special computer store, rather than to a supermarket like Technosila and Eldorado, where scanners are sold next to kettles and irons.That is, go to a place where sellers are more competent in computer technology. And it's best to take with you some friend who "cuts" in "computers". If you know what you want, then sometimes buying in an online store, with an independent choice of device, can save your money to some extent. Best porn site https://noodlemagazine.com - Watch porn.
