NAME
sane-hp5400 - SANE backend for Hewlett-Packard 54XX scanners
DESCRIPTION
The sane-hp5400 library implements a SANE (Scanner Access Now Easy)
backend that provides access to the following Hewlett-Packard USB
flatbed scanners:
ScanJet 5400C
ScanJet 5470C
ScanJet 5490C
More details can be found on the hp5400 backend homepage
http://hp5400backend.sourceforge.net/.
This is ALPHA software. Keep your hand at the scanner's plug and unplug
it, if the head bumps at the end of the scan area. See also the BUGS
section.
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 hp5400.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 54XX 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 hp5400.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
/etc/sane.d/hp5400.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/usr/lib/arch_triplet/sane/libsane-hp5400.a
The static library implementing this backend.
/usr/lib/arch_triplet/sane/libsane-hp5400.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
configuration file is searched in two default directories:
first, the current working directory (".") and then in
/etc/sane.d. 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 SANE_CONFIG_DIR to "/tmp/config:" would result
in directories "tmp/config", ".", and "/etc/sane.d" being
searched (in this order).
SANE_DEBUG_HP5400
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_HP5400=4

BUGS
Scanning is only tested with Linux/ix86/gcc. Be careful when testing on
other operating systems and especially on big-endian platforms. The
scanner may get wrong data.

Opportunity
Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
Free Books
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Education
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
