SANE Scanner Access Now Easy sane-hpsj5s(5)
NAME
sane-hpsj5s - SANE backend for HP ScanJet 5S sheet-fed
scannerDESCRIPTION
The sane-hpsj5s library implements a SANE (Scanner Access
Now Easy) backend that provides access to a parallel portHewlett-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. Itcannot 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 EPP (or EPP+ECP ) mode to operate this scanner. Future versions will support ECP and SPP (Nibble and Byte) modes also. It's planned tosupport 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. TrueColor 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. Emptylines 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 doessane-backends 1.0.19Last change: 24 Feb 2002 1

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 ofSANE_CONFIG_DIR below).

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). ENVIRONMENTSANE_CONFIG_DIR
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 thedirectory separator character, then the default direc-
tories are searched after the explicitly specifieddirectories. For example, setting SANE_CONFIG_DIR to
"/tmp/config:" would result in directories "tmp/config", ".", and "/etc/sane.d" being searched (in this order). sane(7) http://hpsj5s.sourceforge.net http://cyberelk.net/tim/libieee1284 AUTHOR Max Vorobiev Man page mostly based on canon.manATTRIBUTES
