SANE Scanner Access Now Easy sane-hpsj5s(5)
NAME
sane-hpsj5s - SANE backend for HP ScanJet 5S sheet-fed
scanner
DESCRIPTION
The sane-hpsj5s 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 improb-
able) that your scanner will be damaged.
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 EP (or EP]ECP )
mode to operate this scanner. Future versions will support
ECP and SP (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.
Current version implements only gray scale scanning. True
Color and B/W modes are not supported for now.
That said, TESTERS ARE WELCOME. Send your bug reports and
comments to Max Vorobiev .
DEVICE NAMES
This backend expects device names of the form:
special
Where special is the parallel port name in form, libieee1284
expects. It seems to be system dependent. Under Linux it's
parport0, parport1, etc.
CONFIGURATION
The contents of the hpsj5s.conf 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 hpsj5s.conf for this
moment. Future versions will support daisy chain selection.
TIPS
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.
FILES
/etc/sane.d/hpsj5s.conf
The backend configuration file (see also description of
SANECONFIGDIR below).
/usr/lib/sane/libsane-hpsj5s.a
The static library implementing this backend.
/usr/lib/sane/libsane-hpsj5s.so
The shared library implementing this backend (present
on systems that support dynamic loading).
ENVIRONMENT
SANECONFIGDIR
This environment variable specifies the list of direc-
tories 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 direc-
tories are searched after the explicitly specified
directories. For example, setting SANECONFIGDIR to
"/tmp/config:" would result in directories
"tmp/config", ".", and "/etc/sane.d" being searched (in
this order).
