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 coffee printer just like the Stand-Alone Scanner model? What about price, is the combined cost of Scanner and Printer far more than an All in One. Lets look at a few of these issues and more.
Most modern scanners used in the home as well as in small enterprises are used for optically scanning a graphic, a photo or a text document. The most famous kind of scanner available will be the flatbed scanner, sometimes also called the desktop scanner. Documents are typically placed on a sheet of glass and also the lid will then be closed during scanning. There are other handheld scanners and in addition scanners that move the object on the source of light, but we are going to concentrate on the flatbed scanner.
Flatbed scanners normally employ among two techniques for scanning a graphic, a Charge-Coupled Device (CCDD) or perhaps a Contact Image Sensor. The optical sensor, or array of sensors is generally on the moveable arm and possesses red, green and blue (RGB) filters. Quality is usually dependant on colour depth and manufacturers will usually quote the resolution in PPI or Pixels Per Inch, having a typical figure being around 5400 PPI.
In order to process the photo produced by a standalone flatbed scanner, then the link with a personal computer is needed and most flatbed scanners connect with the parent computer through a high-speed USB connection, although a Parallel Serial Port or SCSI (Small Computer Interface) is oftentimes used. A few of the clever stuff is not really within the scanner itself but is going to be located in the Computer Program which actually processes the image. These programs often provide a number of features made to correct difficulties with the image, such as brightness and glare. Another significant feature of these, often bundled software is the ability to edit the created images and to compress those images using some form of lossy compression format such as the popular JPEG format.
Unless the uv flatbed printer is surely an expensive, specialised scanner, then there is often little difference in quality in between the average flatbed scanner as well as a scanner that is certainly part of an All in One system. Among the important factors to consider is the fact that colour depth is at least 24-bit as well as the optical resolution is around 1200 dpi (dots per inch) or better, although a exdldi of 600 dpi is often sufficient if the majority of scanning will be text documents.
An often important factor of an Multi functional Printer, Copier, Scanner is the cabability to be connected to either a wired or wireless network, and quite often both. This allows the output of the scanning facility to shared on the network or easily transmitted being a file or even a file attachment with an email.
Personally, We have used both dtg printer and All in One systems over the years and discover little general difference in quality, however the All in One system is often more practical because of the space saving and the truth that another power outlet does not have to be found for the additional scanner. However, for a small company owner who scans lots of documents, a separate stand-alone scanner will often provide the opportunity to scan and print simultaneously and permit multiple users easier accessibility scanning device.
To summarize, there exists often little difference in quality between material produced with all the stand-alone scanner and that from the multi functional system, except maybe in expensive top end stand-alone models. The multi functional system can be a better purchase for the average home user, whereas a small business might think about the stand-alone choice for flexibility.
