.IX sane\-p5
|
||||
.SH "NAME"
|
||||
sane\-p5 \- SANE backend for the Primax PagePartner
|
||||
.SH "DESCRIPTION"
|
||||
The
|
||||
.B sane\-p5
|
||||
library implements a SANE (Scanner Access Now Easy) backend that
|
||||
provides access to the Primax PagePartner parallel port sheet fed scanner.
|
||||
.PP
|
||||
This backend handles 100, 150, 200, 300 and 600 dpi scan resolutions,
|
||||
in color and gray modes. The 600 dpi is actually 300x600 with lines
|
||||
enlarged to match the vertical resolution.
|
||||
.PP
|
||||
.B EPP/ECP MODES ONLY
|
||||
The current version of the backend uses only EPP or ECP mode to communicate
|
||||
with the scanner. It is
|
||||
recommended that you set your parallel port to EPP in BIOS with the current
|
||||
version of this backend. ECPEPP will only
|
||||
work if you use a 2.4 or 2.6 kernel with ppdev character device support.
|
||||
.PP
|
||||
|
||||
.SH "DEVICE NAMES"
|
||||
This backend expects device names of the form:
|
||||
.PP
|
||||
.RS
|
||||
.I port value
|
||||
.RE
|
||||
.PP
|
||||
Where
|
||||
\fBvalue\fR is :

||||
|
||||

|
||||
.TP
|
||||
auto
|
||||
autodetect all parallel ports and probe
|
||||
them for scanner
|
||||
.TP
|
||||
/dev/parport0
|
||||
uses linux ppdev device, depending on the
|
||||
number of available parallel port, you
|
||||
have to use /dev/parport1, /dev/parport2, ...
|
||||
.PP
|
||||
.RE
|
||||
You can rename any device using the
|
||||
.PP
|
||||
.RS
|
||||
.br
|
||||
.I option name my_name
|
||||
.RE
|
||||
.PP
|
||||
option. This option apply to the last port option.
|
||||
|
||||
.SH "CONFIGURATION"
|
||||
Please make sure to edit dll.conf
|
||||
.B before
|
||||
you use the backend, since this backend isn't enabled by default.

.SH "FILES"
|

.TP
|
||||
.I @CONFIGDIR@/p5.conf
|
||||
The backend configuration file (see also description of
|
||||
.B SANE_CONFIG_DIR
|
||||
below).
|
||||
.TP
|
||||
.I @LIBDIR@/libsane\-p5.a
|
||||
The static library implementing this backend.
|
||||
.TP
|
||||
.I @LIBDIR@/libsane\-p5.so
|
||||
The shared library implementing this backend (present on systems that
|
||||
support dynamic loading).
|
||||
|
||||
.SH "ENVIRONMENT"
|
||||
.TP
|
||||
.B 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 @CONFIGDIR@. 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
|
||||
.B SANE_CONFIG_DIR
|
||||
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
||||
"@CONFIGDIR@" being searched (in this order).
|
||||
.TP
|
||||
.B SANE_DEBUG_P5
|
||||
If the library was compiled with debug support enabled, this
|
||||
environment variable controls the debug level for this backend. E.g.,
|
||||
a value of 255 requests all debug output to be printed. Smaller
|
||||
levels reduce verbosity.

your @CONFIGDIR@/dll.conf.
