Scan wirelessly from old and modern network scanners and multifunction printers without installing manufacturer drivers. Bring old scanner back to life, this app quickly discovers old and new scanners that are wifi connected. We made this app as our Samsung and HP multifunction printer/scanners were no longer supported in macOS or iOS. We found out the scanners used common protocols so developed this app. It should support most modern and older scanners if they support AirPrint or Windows wireless scanning. This scanner app supports the two most common driverless scanning standards used by todayβs wireless scanners: Apple AirScan/eSCL and Microsoft WSD/WS-Scan. In most cases, simply open the app and it will automatically detect compatible scanners on your network. Scan documents, letters, receipts, photos and paperwork directly from your iPhone, iPad or Mac. Choose colour or black-and-white scanning, automatically crop pages, and save your scans as PDF, PNG or JPG files. Works with many major scanner and MFP brands including Brother, Canon, Dell, Epson, HP, Kyocera, Lexmark, OKI, Panasonic, Pantum, Ricoh, Samsung, Sharp and Xerox. Features: * eSCL/AirScan and WSD/WS-Scan support; * Automatic scanner detection, colour or black-and-white scanning; * PDF/PNG/JPG saving; * Automatic document cropping; * Oo manufacturer scanner driver required; Compatibility: Most wireless scanners and multifunction printers that support eSCL/AirScan or WSD/WS-Scan are expected to work.
