NAME

       sane-hp4200 - SANE backend for Hewlett-Packard 4200 scanners

DESCRIPTION

       The  sane-hp4200  library  implements  a SANE (Scanner Access Now Easy)
       backend that provides  access  to  the  following  Hewlett-Packard  USB
       flatbed scanners:

              ScanJet 4200 C
              ScanJet 4200 Cxi
              ScanJet 4200 Cse

       More   details   can   be   found   on   the  hp4200  backend  homepage
       http://hp4200-backend.sourceforge.net/.

       This is BETA software. Keep your hand at the scanner's plug and  unplug
       it, if the head bumps at the end of the scan area.

       If  you  own a scanner other than the ones listed above that works with
       this backend, please let us know this by sending  the  scanner's  exact
       model   name   and   the   USB   vendor   and  device  ids  (e.g.  from
       /proc/bus/usb/devices, sane-find-scanner(1) or syslog) to us.  Even  if
       the scanner's name is only slightly different from the models mentioned
       above, please let us know.

CONFIGURATION

       The  contents of the hp4200.conf file is a list of usb lines containing
       vendor and product ids that correspond to USB scanners.  The  file  can
       also  contain  the  names of device files that correspond to an HP 4200
       scanner.  Empty lines and lines starting with a hash mark (#)  are  ig-
       nored.   The  scanners  are  autodetected  by  usb vendor_id product_id
       statements which are already included  into  hp4200.conf.   "vendor_id"
       and  "product_id" are hexadecimal numbers that identify the scanner. If
       autodetection does not work, add the device name of your scanner to the
       configuration file, e.g.  /dev/usb/scanner0.

FILES

       /usr/local/etc/sane.d/hp4200.conf
              The  backend  configuration  file  (see  also   description   of
              SANE_CONFIG_DIR below).

       /usr/local/lib/sane/libsane-hp4200.a
              The static library implementing this backend.

       /usr/local/lib/sane/libsane-hp4200.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).

ENVIRONMENT

       SANE_CONFIG_DIR
              This environment variable specifies the list of directories that
              may contain the configuration file.  On *NIX systems, the direc-
              tories are separated by a colon (`:'), under OS/2, they are sep-
              arated  by a semi-colon (`;').  If this variable is not set, the
              configuration file  is  searched  in  two  default  directories:
              first,  the  current working directory (.)  and then in /usr/lo-
              cal/etc/sane.d.  If the value of the environment  variable  ends
              with  the directory separator character, then the default direc-
              tories are searched after the explicitly specified  directories.
              For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
              sult in directories tmp/config, ., and /usr/local/etc/sane.d be-
              ing searched (in this order).

       SANE_DEBUG_HP4200
              If the library was compiled with debug support enabled, this en-
              vironment  variable  controls  the debug level for this backend.
              Higher debug levels increase the verbosity of the output.

              Example: export SANE_DEBUG_HP4200=4

BUGS

       Tested only with Linux.

       Only 8 bit color mode works.

       Scanning is slow due to backtracking.
