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 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.  Under UNIX, the directories
              are separated by a colon (`:'), under OS/2, they  are  separated
              by a semi-colon (`;').  If this variable is not set, the config-
              uration 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/lo-
              cal/etc/sane.d" being 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.
