sane-hpsj5s - SANE backend for HP ScanJet 5S sheetfed scanner

<H2>DESCRIPTION</H2><PRE>
|
|
|
|
|
The <B>sane-hpsj5s</B> library implements a SANE (Scanner Access Now Easy)
|
|
|
|
|
backend that provides access to parallel port Hewlett-Packard ScanJet
|
|
|
|
|
5S scaner.
|
|
|
|
|
|
|
|
|
|
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 unprobable) that your scanner will be damaged.
|
|
|
|
|
|
|
|
|
|
LIMITATIONS: For now this backend works only at Linux platform.This
|
|
|
|
|
limitation is due dependance on libieee1284 library. If your system
|
|
|
|
|
supports libieee1284 too, this backend should work. If you ported
|
|
|
|
|
libieee1284 for you platform, please let me know.Your system should
|
|
|
|
|
support <B>EPP</B> (or <B>EPP+ECP</B> ) mode to operate this scaner. Future versions
|
|
|
|
|
will support ECP and SPP (Nibble and Byte) modes also. It's planned to
|
|
|
|
|
support for scaners not only at 0 daisy-chain position, but at any one.
|
|
|
|
|
Support for multiple scaners could be implemented too.
|
|
|
|
|
|
|
|
|
|
Current version implements only gray scale scaning. 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, libieee1284 expects.
|
|
|
|
|
It seems to be system dependent. Under Linux it's parport0, parport1,
|
|
|
|
|
etc.

|
<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.

<H2>TIPS</H2><PRE>
|
|
|
|
|
It seems that HP ScanJet 5S scaner uses software noise correction. This
|
|
|
|
|
feature is not implemented for now. So does gamma correction and cali-
|
|
|
|
|
bration. I'll handle it in future versions. Native resolution for
|
|
|
|
|
this scaner is 300 DPI. Other modes could be jagged in some ways.

<H2>ENVIRONMENT</H2><PRE>
|

|
|
|
<B>SANE_CONFIG_DIR</B>
|
|
|
|
|
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
|
|
|
|
|
/usr/local/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 directo-
|
|
|
|
|
ries. For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:"
|
|
|
|
|
would result in directories "tmp/config", ".", and
|
|
|
|
|
"/usr/local/etc/sane.d" being searched (in this order).
