The question whether to buy a Stand-Alone Scanner or go for an All in One printer raises many questions. Do you have space for a scanner and a printer? Is the scanning function and resolution as good with cafe printer just like the Stand-Alone Scanner model? Have you thought 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 your home as well as in small companies can be used as optically scanning a picture, a photograph or even a text document. The most popular kind of scanner to be found is definitely the flatbed scanner, sometimes also referred to as the desktop scanner. Documents are normally put on a sheet of glass and the lid will be closed during scanning. There are more handheld scanners and also scanners that move the object within the source of light, but we are going to concentrate on the flatbed scanner.
Flatbed scanners normally employ among two methods for scanning an image, a Charge-Coupled Device (CCDD) or a Contact Image Sensor. The optical sensor, or variety of sensors is usually on the moveable arm and contains red, green and blue (RGB) filters. Quality is generally based on colour depth and manufacturers will usually quote the resolution in PPI or Pixels Per Inch, using a typical figure being around 5400 PPI.
To be able to process the picture produced by a standalone flatbed scanner, then a connection to a computer is required and most flatbed scanners get connected to the parent computer by means of a high speed USB connection, although a Parallel Serial Port or SCSI (Small Computer System Interface) is sometimes used. Some of the clever stuff is not really within the scanner itself but is going to be based in the Computer Program which actually processes the picture. These programs often provide numerous features created to correct difficulties with the picture, including brightness and glare. Another important feature of the, often bundled software is the cabability to edit the created images and to compress those images using some form of lossy compression format like the popular JPEG format.
Unless the phone case printer is surely an expensive, specialised scanner, then there is often little difference in quality between the average flatbed scanner and a scanner which is element of an All-in-one system. One of the important things to look for is the fact that colour depth reaches least 24-bit and the optical resolution is approximately 1200 dpi (dots per inch) or better, although a exdldi of 600 dpi is usually adequate if nearly all scanning is to be text documents.
An often important factor of an All in One Printer, Copier, Scanner is the opportunity to be linked 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 method is often more practical as a result of space saving and the fact that another power outlet does not have that can be found for the additional scanner. However, for a small company owner who scans lots of documents, a different stand-alone scanner will often provide the opportunity to scan and print simultaneously and permit multiple users easier accessibility scanning device.
To summarize, there is certainly often little difference in quality between material produced with all the stand-alone scanner which from the all in one system, except maybe in expensive top end stand-alone models. The multi functional system is usually a better purchase for the typical home user, whereas your small business might think about the stand alone option for flexibility.
