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. David /\/elson [e-mail] http://www.jump.net/~dnelson
