The program that came bundled with your scanner is probably good for controlling the quality of your scans but that’s just half the job done because image scans aren’t searchable and are therefore impossible to manage in the long term. The scanner helps you bring existing paper documents like letters, invoices, books and faxes into the computer while the OCR software converts these scanned images into editable and searchable formats like PDF or Microsoft Word. A scanner and an OCR software are the key components of a “paperless office”.
