|
|
sane-hpsj5s - SANE backend for HP ScanJet 5S sheet-fed scanner
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-hpsj5s</B> library implements a SANE (Scanner Access Now Easy)
|
|
backend that provides access to a parallel port Hewlett-Packard ScanJet
|
|
5S scanner.
|
|
|
|
IMPORTANT: this is alpha code. Don't expect this to work correctly.
|
|
Many functions are missing, others contain errors. In some cases, your
|
|
computer might even hang. It cannot be excluded (although I consider it
|
|
extremely improbable) that your scanner will be damaged.
|
|
|
|
LIMITATIONS: For now this backend works only on Linux. This limitation
|
|
is due to dependence on the <B><A HREF="libieee1284.3.html">libieee1284(3)</A></B> library. If your system sup-
|
|
ports <B><A HREF="libieee1284.3.html">libieee1284(3)</A></B> too, this backend should work. If you ported <B>li-</B>
|
|
<B><A HREF="bieee1284.3.html">bieee1284(3)</A></B> for your platform, please let me know. Your system should
|
|
support <B>EPP</B> (or <B>EPP+ECP</B>) mode to operate this scanner. Future versions
|
|
will support ECP and SPP (Nibble and Byte) modes also. It's planned to
|
|
support scanners not only at daisy-chain position 0, but anywhere. Sup-
|
|
port for multiple scanners could be implemented too.
|
|
|
|
Current version implements only gray scale scanning. True Color and B/W
|
|
modes are not supported for now.
|
|
|
|

<H2>DEVICE NAMES</H2><PRE>
|
|
This backend expects device names of the form:
|
|
|
|
<I>special</I>
|
|
|
|
Where <I>special</I> is the parallel port name in form, <B><A HREF="libieee1284.3.html">libieee1284(3)</A></B> ex-
|
|
pects. It seems to be system dependent. Under Linux it's parport0, par-
|
|
port1, etc.
|
|
|
|
|
|
</PRE>
|
|
<H2>CONFIGURATION</H2><PRE>
|
|
The contents of the <I>hpsj5s.conf</I> file is a list of parport names that
|
|
correspond to HP ScanJet 5S scanners. Empty lines and lines starting
|
|
with a hash mark (#) are ignored. Only one device name can be listed
|
|
in <I>hpsj5s.conf</I> for this moment. Future versions will support daisy
|
|
chain selection.
|
|
|
|
|
|
</PRE>
|
|
<H2>TIPS</H2><PRE>
|
|
It seems that HP ScanJet 5S scanner uses software noise correction.
|
|
This feature, along with gamma correction and calibration, are not im-
|
|
plemented for now. They will be handled in future versions. Native
|
|
resolution for this scanner is 300 DPI. Other modes may present alias-
|
|
ing artifacts.
|
|
|
|
|
|
</PRE>
|
|
<H2>FILES</H2><PRE>
|
|
<I>/usr/local/etc/sane.d/hpsj5s.conf</I>
|
|
The backend configuration file (see also description of
|
|
<B>SANE_CONFIG_DIR</B> below).
|
|
|
|
<I>/usr/local/lib/sane/libsane-hpsj5s.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-hpsj5s.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_CONFIG_DIR</B>
|
|
This environment variable specifies the list of directories that
|
|
may contain the configuration file. On *NIX systems, the direc-
|
|
tories are separated by a colon (`:'), under OS/2, they are sep-
|
|
arated 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 <I>/usr/lo-</I>
|
|
<I>cal/etc/sane.d</I>. 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 <B>SANE_CONFIG_DIR</B> to "/tmp/config:" would re-
|
|
sult in directories <I>tmp/config</I>, <I>.</I>, and <I>/usr/local/etc/sane.d</I> be-
|
|
ing searched (in this order).
|
|
|
|
<B>SANE_DEBUG_HPSJ5S</B>
|
|
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.
