sane-hpsj5s(5) SANE Scanner Access Now Easy sane-hpsj5s(5)NAMEsane-hpsj5s - SANE backend for HP ScanJet 5S sheetfed
scanner
DESCRIPTION
The sane-hpsj5s 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
EPP (or EPP+ECP ) mode to operate this scaner. Future ver-
sions 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.
That said, TESTERS ARE WELCOME. Send your bug reports and
comments to Max Vorobiev <pcwizard@yandex.ru>.
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 selec-
tion.
TIPS
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.
FILES
/usr/freeware/etc/sane.d/hpsj5s.conf
The backend configuration file (see also
description of SANE_CONFIG_DIR below).
/usr/freeware/lib32/sane/libsane-hpsj5s.a
The static library implementing this backend.
/usr/freeware/lib32/sane/libsane-hpsj5s.so
The shared library implementing this backend (pre-
sent on systems that support dynamic loading).
ENVIRONMENT
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 /usr/freeware/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 spec-
ified directories. For example, setting SANE_CON-
FIG_DIR to "/tmp/config:" would result in directo-
ries "tmp/config", ".", and "/usr/free-
ware/etc/sane.d" being searched (in this order).
