These scanners offer more than the 24 bits of color (8 bits each for red, green, and blue) you’ll find on lower-end models. These timesaving features are useful, but you can achieve the same results with a scanner and the appropriate software. All but the CanoScan let you send a scanned image directly to a printer, attach it to an e-mail, run it through an OCR program to convert it to editable text, and even share it on the Web, by using buttons on the scanners themselves. High-resolution scanning isn’t the only thing these scanners are good for. All the scanners include TWAIN drivers to provide easy access to applications that support this feature, such as Adobe Photoshop, Microsoft Office, and OCR (optical character recognition) software such as OmniPage. Precisionscan Pro’s interface, for example, felt very Mac-centric, with intuitive controls and menu structures that put the important features in the main window. All the scanners’ software had these controls, but HP’s Precisionscan Pro software and Canon’s CanoScan software lead the rest in terms of usability. Scanning software should be easy to use and flexible enough to guide novices through useful presets while allowing experts to change parameters such as gamma curves, shadow and highlight control, brightness and contrast, and color correction.
