NAME

6       sane-hp4200 - SANE backend for Hewlett-Packard 4200 scanners
7

DESCRIPTION

9       The  sane-hp4200  library  implements  a SANE (Scanner Access Now Easy)
10       backend that provides  access  to  the  following  Hewlett-Packard  USB
11       flatbed scanners:
12
13              ScanJet 4200 C
14              ScanJet 4200 Cxi
15              ScanJet 4200 Cse
16
17       More   details   can   be   found   on   the  hp4200  backend  homepage
18       http://hp4200-backend.sourceforge.net/.
19
20       This is BETA software. Keep your hand at the scanner's plug and  unplug
21       it, if the head bumps at the end of the scan area.
22
23       If  you  own a scanner other than the ones listed above that works with
24       this backend, please let us know this by sending  the  scanner's  exact
25       model   name   and   the   USB   vendor   and  device  ids  (e.g.  from
26       /proc/bus/usb/devices, sane-find-scanner or syslog) to us. Even if  the
27       scanner's  name  is  only  slightly different from the models mentioned
28       above, please let us know.

CONFIGURATION

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

FILES

42       /etc/sane.d/hp4200.conf
43              The  backend  configuration  file  (see  also   description   of
44              SANE_CONFIG_DIR below).
45
46       /usr/lib64/sane/libsane-hp4200.a
47              The static library implementing this backend.
48
49       /usr/lib64/sane/libsane-hp4200.so
50              The shared library implementing this backend (present on systems
51              that support dynamic loading).
52

ENVIRONMENT

54       SANE_CONFIG_DIR
55              This environment variable specifies the list of directories that
56              may contain the configuration file.  Under UNIX, the directories
57              are separated by a colon (`:'), under OS/2, they  are  separated
58              by a semi-colon (`;').  If this variable is not set, the config‐
59              uration file is searched in two default directories: first,  the
60              current working directory (".") and then in /etc/sane.d.  If the
61              value of the environment variable ends with the directory  sepa‐
62              rator character, then the default directories are searched after
63              the explicitly  specified  directories.   For  example,  setting
64              SANE_CONFIG_DIR  to  "/tmp/config:"  would result in directories
65              "tmp/config", ".", and "/etc/sane.d"  being  searched  (in  this
66              order).
67
68       SANE_DEBUG_HP4200
69              If  the  library  was  compiled with debug support enabled, this
70              environment variable controls the debug level for this  backend.
71              Higher debug levels increase the verbosity of the output.
72
73              Example: export SANE_DEBUG_HP4200=4

BUGS

88       Tested only with Linux.
89
90       Only 8 bit color mode works.
91
92       Scanning is slow due to backtracking.
