The HP ScanJet 5590 printer scan works like any other scanner but in the form of a printer. All you need to do is to set up the document to be scanned on the machine. Once your HP ScanJet 5590 printer has detected the document, change the settings of the machine to 'Scan' and allow it to scan the whole document. This can be saved as a digital document on your connected machine. After the connection has been built, you can start using the device for printing and scanning.
