CHANGES
- Amended for Linux-2.3.40
- Updated for multiple scanner support
INTRODUCTION
This document will hopefully provide enough info on how to get SANE
working with a Hewlett Packard USB capable scanner using the USB
interface. The majority of HP Scanners support the Scanner Control
Language (SCL) which is both published by HP and supported by SANE.
The only HP Scanners that I'm aware of that do not support SCL are the
4200C and the 3300C. All other HP scanners with USB interfaces should
work (4100C, 5200C, 6200C, and 6300C). Of course as HP releases new
scanners this information may change.
REQUIREMENTS
In order to get this running you'll need USB support in your kernel in
addition to USB Scanner support. Please refer to scanner.txt for
issues pertaining to Linux USB and USB Scanner support.
An installed version of SANE which is available from
http://www.mostang.com/sane/. Testing has been performed using
version SANE-1.0.1. For instructions on building and installing SANE,
refer to the various README files within the SANE distribution.
The latest SANE HP backend is available from http://www.kirchgessner.net.
At the time of this writing, version 0.83 was available.
OK, I'VE INSTALLED SANE. SO WHAT DO I DO NOW?
NOTE: $INSTALL_DIR is the location where SANE is installed. It may
be /usr/local, /usr, /opt or somewhere else. If you don't know, ask
your system administrator.
1) Make sure that you have the libsane-hp.* libraries under the
$INSTALL_DIR/lib/sane/ directory. If you don't, then the HP backend
was either not compiled or installed properly.
2) Under the directory $INSTALL_DIR/etc/sane.d/ edit the following
files: dll.conf, hp.conf.
dll.conf: Make sure that the 'hp' entry is present and uncommented.
hp.conf: This should contain two lines:
/dev/usbscanner
option connect-device
NOTE: If you are using multiple scanners, make sure to have the correct
devince, ie /dev/usbscanner0. See scanner.txt for more info.
3) You should now be able to use SANE (xscanimage or scanimage).
Don't forget to read any relevant man pages regarding the usage of
SANE. If you have other entries uncommented in dll.conf, you may have
to specify the device to (x)scanimage. Again, `man` is your friend.
The xscanimage (1) man page has info on how to get 'The Gimp' to work
with xscanimage. Note that Gimp support must be compiled into SANE
for it work. If you are dealing with a RedHat system, this means that
you'll also need to install the gimp-devel rpm package.
NOTE: The issues regarding core dumping by (x)scanimage have (or seem
to be thus far) been resolved with version 0.2+ of the USB scanner
driver which should be available in linux-2.3.23. If you notice
otherwise, please contact me.
