sane-hpsj5s - SANE backend for HP ScanJet 5S sheet-fed scanner
|

|
|
<H2>DESCRIPTION</H2>
|
|
|
|
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.
|
|
<P>
|
|
|
|
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.
|
|
<P>
|
|
|
|
LIMITATIONS: For now this backend works only on Linux. This limitation
|
|
is due to dependence on the libieee1284 library. If your system supports libieee1284 too,
|
|
this backend should work. If you ported libieee1284 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. Support for multiple scanners could
|
|
be implemented too.
|
|
<P>
|
|
|
|
Current version implements only gray scale scanning. True Color and B/W modes are
|
|
not supported for now.
|
|
<P>
|
|

<H2>DEVICE NAMES</H2>

This backend expects device names of the form:

<P>
|
|
|
|
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>
|
|
|
|
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.

<P>

It seems that HP ScanJet 5S scanner uses software noise correction. This
|
|
feature is not implemented for now. So does gamma correction and calibration.
|
|
I'll handle it in future versions.
|
|
Native resolution for this scanner is 300 DPI. Other modes could be jagged in some
|
|
ways.

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</B>
|
|
|
|
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
|
"@CONFIGDIR@" being searched (in this order).
