.SH NAME
|
||
|
|
sane-hpsj5s - SANE backend for HP ScanJet 5S sheetfed scanner
|
||
|
|
.SH DESCRIPTION
|
||
|
|
The
|
||
|
|
.B sane-hpsj5s
|
||
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
||
|
|
provides access to parallel port Hewlett-Packard ScanJet 5S scaner.
|
||
|
|
.PP
|
||
|
|
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.
|
||
|
|
.PP
|
||
|
|
LIMITATIONS: For now this backend works only at Linux+PC platform.This limitation
|
||
|
|
is due dependance on Linux loadable module. Will be fixed in future. Your system
|
||
|
|
should support
|
||
|
|
.B EPP
|
||
|
|
(or
|
||
|
|
.B EPP+ECP
|
||
|
|
) 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.
|
||
|
|
.PP
|
||
|
|
Current version implements only gray scale scaning. True Color and B/W modes are
|
||
|
|
not supported for now.

.SH "DEVICE NAMES"
|
||
|
|
This backend expects device names of the form:
|
||
|
|
.PP
|
||
|
|
.RS
|
||
|
|
.I special
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
Where
|
||
|
|
.I special
|
||
|
|
is the path-name for the special device that corresponds to hpsj5s scaner driver.
|
||
|
|
The special device name must be a link to device file or device file of hpsj5s.
|
||
|
|
Under Linux, such a device name could be
|
||
|
|
.I /dev/hpsj5s
|
||
|
|
for example.
|
||
|
|
|
||
|
|
.SH CONFIGURATION
|
||
|
|
The contents of the
|
||
|
|
.I hpsj5s.conf
|
||
|
|
file is a list of device 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
|
||
|
|
.IR hpsj5s.conf
|
||
|
|
for this moment.
|
||
|
|
|
||
|
|
.SH TIPS
|
||
|
|
.PP
|
||
|
|
It seems that HP ScanJet 5S scaner 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 scaner is 300 DPI. Other modes could be jagged in some
|
||
|
|
ways.

.SH FILES
|
||
|
|
.TP
|
||
|
|
.I @CONFIGDIR@/hpsj5s.conf
|
||
|
|
The backend configuration file (see also description of
|
||
|
|
.B SANE_CONFIG_DIR
|
||
|
|
below).
|
||
|
|
.TP
|
||
|
|
.I @LIBDIR@/libsane-hpsj5s.a
|
||
|
|
The static library implementing this backend.
|
||
|
|
.TP
|
||
|
|
.I @LIBDIR@/libsane-hpsj5s.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).
