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

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