Even the multi-fuction inkjet printers, which have scanner, printer and copier functions, are cheaper now-a-days. If you have a scanner or a multi-function printer, then you can scan any of your documents, pictures and anything on a paper and save it as JPEG image in your PC. While some of the scanners allow you to save the scanned documents as PDF files, others can only save in the BMP, JPG or PNG file formats.
