(Sorry for the inconvenience)
Beginning with PC-BSD® 9.1, Control Panel provides an icon for accessing XSane, a graphical utility for managing scanners.
To use your scanner, make sure the device is plugged into the PC-BSD® system and click the Scanner icon in Control Panel or type xsane from the command line. A pop-up message will indicate that XSane is detecting devices and will prompt you to accept the XSane license if a device is detected. If a device is not detected, search for your device at the list of supported scanners.
NOTE: if the scanner is part of an HP All-in-One device, make sure that HPLIP is first installed in Control Panel -> System Manager -> System Packages -> Hardware-Drivers.
Figure 8.13a shows the XSane interface running on a PC-BSD® system attached to an HP OfficeJet.
