39 <para>
40 <application>SANE</application> is short for Scanner Access Now Easy.
41 Scanner access, however, is far from easy, since every vendor has their
42 own protocols. The only known protocol that should bring some unity into
43 this chaos is the TWAIN interface, but this is too imprecise to allow a
44 stable scanning framework. Therefore, <application>SANE</application>
45 comes with its own protocol, and the vendor drivers can't be used.
46 </para>
47
48 <para>
49 <application>SANE</application> is split into back ends and front ends.
50 The back ends are drivers for the supported scanners and cameras. The
51 front ends are user interfaces to access the backends.

169 To access your scanner, you will probably need the related kernel
170 drivers and/or additional support packages. A SCSI scanner will need SCSI
171 drivers, a parallel port scanner needs parallel port support (you should
172 use enhanced EPP modes) and perhaps <ulink
173 url="http://cyberelk.net/tim/libieee1284/">libieee1284</ulink>, and a USB
174 scanner will need the <xref linkend="libusb"/> package. For HP devices,
175 you may need <ulink
176 url="http://sourceforge.net/projects/hplip/files/hplip/">hplip</ulink>.
177 Ensure you have the necessary drivers properly configured to access
178 the devices.
