button-controlled This option can be used in combination with scanadf(1) and scanimage(1) in batch mode, for example when you want to scan many photos or multiple-page documents. If it is enabled (i.e. is set to true or yes), the backend waits before every scan until the user presses the "SCAN" button (for MP150) or the color-scan button (for other models). Just put the first page in the scanner, press the button, then the next page, press the button and so on. When you finished, press the gray-scan button. (For MP150 you have to stop the frontend by pressing Ctrl-C for example.)
