The question whether to get a Stand-Alone Scanner or choose an All in One printer raises many questions. Have you got space for a scanner and a printer? Is the scanning function and resolution pretty much as good with an Multi functional printer similar to the Stand-Alone Scanner model? What about price, is the combined cost of Scanner and Printer a lot more than an All in One. Lets consider many of these issues and more.
Most modern scanners used in the house as well as in small companies can be used for optically scanning a picture, a photograph or perhaps a text document. The most famous form of scanner to get found is definitely the flatbed scanner, sometimes also known as the desktop scanner. Documents are normally put on a sheet of glass and the lid is then closed during scanning. There are more handheld scanners and in addition Coffee Printer that move the object on the light source, but we are going to concentrate on the flatbed scanner.
Flatbed scanners normally employ certainly one of two techniques for scanning a picture, a Charge-Coupled Device (CCDD) or perhaps a Contact Image Sensor. The optical sensor, or selection of sensors is normally over a moveable arm and has red, green and blue (RGB) filters. Quality is generally dependant on colour depth and manufacturers will often quote the resolution in PPI or Pixels Per Inch, having a typical figure being around 5400 PPI.
In order to process the picture produced by a standalone flatbed scanner, then a link with a personal computer is required and many Uv Printer connect with the parent computer through a high speed USB connection, although a Parallel Serial Port or SCSI (Small Computer System Interface) may also be used. A few of the clever stuff will not be in the scanner itself but is going to be found within the Computer Program which actually processes the picture. These programs often provide a number of features designed to correct problems with the picture, such as brightness and glare. Another significant feature of these, often bundled application is the cabability to edit the created images and also to compress those images using some type of lossy compression format like the most popular JPEG format.
Unless the flatbed scanner is surely an expensive, specialised scanner, then there is often little difference in quality involving the average flatbed scanner as well as a scanner that is certainly part of an All in One system. One of the important factors to consider would be that the colour depth are at least 24-bit as well as the optical resolution is approximately 1200 dpi (dots per inch) or better, although a resolution of 600 dpi is often adequate if nearly all scanning is going to be text documents.
An often important aspect of the All in One Printer, Copier, Scanner is the opportunity to be attached to either a wired or wireless network, and quite often both. This enables the production of the scanning facility to shared on the network or easily transmitted as a file or even a file attachment for an email.
Personally, I actually have used both Tshirt Printer and Multi functional systems through the years and discover little general difference in quality, nevertheless the Multi functional system is often more practical as a result of space saving and the truth that a separate power outlet does not have to get found for that additional scanner. However, for a small company owner who scans a whole lot aiszqz documents, a different stand-alone scanner will often provide the ability to scan and print simultaneously and permit multiple users easier access to the scanning device.
To summarize, there is often little difference in quality between material produced using the stand-alone scanner and this in the all in one system, except maybe in expensive top end stand-alone models. The all-in-one system can be a better buy for the normal home user, whereas your small business might take into account the stand-alone option for flexibility.
