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

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

This is BETA software. Keep your hand at the scanner's plug and unplug it, if
|
2005-08-13 15:30:02 +00:00
|
|
|
the head bumps at the end of the scan area.
|
|
|
|
.PP
|
|
|
|
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
|
|
|
|
.IR /proc/bus/usb/devices ,
|
|
|
|
.I 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.

.SH CONFIGURATION
|
|
|
|
The contents of the
|
|
|
|
.I 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
|
|
|
|
.B usb vendor_id product_id
|
|
|
|
statements which are already included into
|
|
|
|
.IR 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.
|
|
|
|
.IR /dev/usb/scanner0 .
|
|

|
.SH FILES
|
|
|
|
.TP
|
|
|
|
.I @CONFIGDIR@/hp4200.conf
|
|
|
|
The backend configuration file (see also description of
|
|
|
|
.B SANE_CONFIG_DIR
|
|
|
|
below).
|
|
|
|
.TP
|
|
|
|
.I @LIBDIR@/libsane-hp4200.a
|
|
|
|
The static library implementing this backend.
|
|
|
|
.TP
|
|
|
|
.I @LIBDIR@/libsane-hp4200.so
|
|
|
|
The shared library implementing this backend (present on systems that
|
|
|
|
support dynamic loading).
|
|
|
|
.SH ENVIRONMENT
|
|
|
|
.TP
|
|
|
|
.B 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 configuration file
|
|
|
|
is searched in two default directories: first, the current working
|
|
|
|
directory (".") and then in @CONFIGDIR@. If the value of the
|
|
|
|
environment variable ends with the directory separator character, then
|
|
|
|
the default directories are searched after the explicitly specified
|
|
|
|
directories. For example, setting
|
|
|
|
.B SANE_CONFIG_DIR
|
|
|
|
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
|
|
|
"@CONFIGDIR@" being searched (in this order).
|
|
|
|
.TP
|
|
|
|
.B SANE_DEBUG_HP4200
|
|
|
|
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
|
