sane-hpsj5s - SANE backend for HP ScanJet 5S sheetfed scanner
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 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
Current version implements only gray scale scaning. True Color and B/W modes are not sup-
ported for now.
That said, TESTERS ARE WELCOME. Send your bug reports and comments to Max Vorobiev <pcwiz-
This backend expects device names of the form:
Where special is the parallel port name in form, libieee1284 expects. It seems to be sys-
tem dependent. Under Linux it's parport0, parport1, etc.
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.
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
The backend configuration file (see also description of SANE_CONFIG_DIR below).

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).
