sane-hpsj5s - SANE backend for HP ScanJet 5S sheet-fed scanner
The sane-hpsj5s library implements a SANE (Scanner Access Now Easy)
backend that provides access to a parallel port Hewlett-Packard ScanJet
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.
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 EPP (or EPP+ECP ) 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.
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 <firstname.lastname@example.org>.
This backend expects device names of the form:
Where special is the parallel port name in form, libieee1284 expects.
It seems to be system dependent. Under Linux it’s parport0, parport1,
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
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.

The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
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
/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 directories. For
example, setting SANE_CONFIG_DIR to "/tmp/config:" would result
in directories "tmp/config", ".", and "/etc/sane.d" being
searched (in this order).
