Documentation/usb/scanner-hp-sane.txt

-Copyright (C) 1999, 2000 David E. Nelson
-
-April 26, 2000
-
-CHANGES
-
-- Amended for Linux-2.3.99-pre6-3
-- 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 ,3300C, and the PhotoSmart S20.  All other HP scanners with USB
-interfaces should work (4100C, 5200C, 6200C, and 6300C) as do models
-that are derived from the models above. ie the 6350C which is a 6300C
-with a transparency adaptor included with the scanner at time of
-purchase.  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
-device, 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 to work.  If you are dealing with a RedHat system, this
-means that you'll also need to install the gimp-devel rpm package
-prior to compiling SANE.
-
-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.
