The question if you should buy a Stand-Alone Scanner or opt for an Multi functional printer raises many questions. Do you have 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? How about price, is the combined price of Scanner and Printer a lot more than an All in One. Lets look at some 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 picture or even a text document. The most famous form of scanner to be found will be the flatbed scanner, sometimes also known as the desktop scanner. Documents are usually put on a sheet of glass and the lid will then be closed during scanning. There are many handheld scanners and in addition scanners that move the object within the source of light, but we are going to concentrate on the flatbed scanner.
Flatbed scanners normally employ one of two options for scanning an image, a Charge-Coupled Device (CCDD) or perhaps a Contact Image Sensor. The optical sensor, or selection of sensors is usually on the moveable arm and has red, green and blue (RGB) filters. Quality is usually 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.
To be able to process the image produced by a standalone flatbed scanner, then the connection to a personal computer is required 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 number of the clever stuff is not really within the scanner itself but will be located in the Computer Program that actually processes the picture. These programs often provide a number of features designed to correct problems with the image, such as brightness and glare. Another essential feature of such, often bundled software is the opportunity to edit the created images and also to compress those images using some form of lossy compression format just like the popular JPEG format.
Unless the uv printer is definitely an expensive, specialised scanner, there is often little difference in quality involving the average flatbed scanner as well as a scanner that is certainly element of an All in One system. One of the important things to look for is that the colour depth is at least 24-bit and also the optical resolution is approximately 1200 dpi (dots per inch) or better, although a exdldi of 600 dpi is often adequate if the majority of scanning will be text documents.
An often important factor of your Multi functional Printer, Copier, Scanner is the opportunity to be linked to either a wired or wireless network, and sometimes both. This permits the production of the scanning facility to shared on the network or easily transmitted as a file or possibly a file attachment with an email.
Personally, We have used both t-shirt printer and All-in-one systems over time and find little general difference in quality, however the All in One product is often more practical because of the space saving and the fact that a different power outlet does not have to be found for that additional scanner. However, for a small business owner who scans a lot of documents, another stand-alone scanner will usually provide the opportunity to scan and print simultaneously and enable multiple users easier access to the scanning device.
To sum up, there is often little difference in quality between material produced with all the stand-alone scanner and this of the all-in-one system, except maybe in expensive top end stand-alone models. The all-in-one system is often a better purchase for the normal home user, whereas your small business might consider the stand alone choice for flexibility.
