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

       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

       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.

       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
       ignored.	 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.

	      The  backend  configuration  file	 (see  also   description   of
	      SANE_CONFIG_DIR below).

	      The static library implementing this backend.

	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

	      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	 /sys‐
	      tem/resources/sane-backends/1.0.18/etc/sane.d.  If the value  of
	      the environment variable ends with the directory separator char‐
	      acter, then the  default	directories  are  searched  after  the
	      explicitly   specified   directories.    For   example,  setting
	      SANE_CONFIG_DIR to "/tmp/config:" would  result  in  directories
	      "tmp/config",	".",	 and	 "/system/resources/sane-back‐
	      ends/1.0.18/etc/sane.d" being searched (in this order).

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

	      Example: export SANE_DEBUG_HP4200=4

       sane(7), sane-usb(5),

       Tested only with Linux.

       Only 8 bit color mode works.

       Scanning is slow due to backtracking.
