.SH "DEVICE NAMES"
This backend's default device is:
.PP
.RS
.I 0x378
.RE
.PP
This "default device" will be used if no configuration
file can be found. It is the base address of the parallel port
on i386 machines.
.PP
As the backend supports up to four devices, it is possible to
specify them in the configuration file
.PP
.RS
.I @CONFIGDIR@/plustek_pp.conf
.RE
.PP
See this file for examples.
.PP
.SH "CONFIGURATION"
.PP
This section describes the backend's configuration file entries.
The file is located at:
.I @CONFIGDIR@/plustek_pp.conf
.PP
For a proper setup, you will need at least two entries:
.RS
.PP
.I [direct]
.br
.I device 0x378
.RE
.PP
.I direct
tells the backend, that the following devicename (here
.IR 0x378 )
has to be interpreted as parallel port scanner device. In
fact it is the address to use. Alternatively you can use
.I /dev/parport0
if the backend has been compiled with libieee1284 support.
.PP
Further options:
.PP
option warmup t
.RS
.I t
specifies the warmup period in seconds
.RE
.PP
option lampOff t
.RS
.I t
is the time in seconds for switching off the lamps in
standby mode
.RE
.PP
option lOffonEnd b
.RS
.I b
specifies the behaviour when closing the backend, 1 --> switch
lamps off, 0 --> do not change lamp status
.RE
.PP
option mov m
.RS
.I m
is the model override switch, which only works in direct mode.
.TP
.IR m " = 0"
default: no override
.TP
.IR m " = 1"
OpticPro 9630PL override (works if OP9630
has been detected) forces legal size (14")
.TP
.IR m " = 2"
Primax 4800Direct override (works if OP600
has been detected) swaps red/green color
.TP
.IR m " = 3"
OpticPro 9636 override (works if OP9636 has
been detected) disables backends
transparency/negative capabilities
.TP
.IR m " = 4"
OpticPro 9636P override (works if OP9636 has
been detected) disables backends
transparency/negative capabilities
.TP
.IR m " = 5"
OpticPro A3I override (works if OP12000 has
been detected) enables A3 scanning
.TP
.IR m " = 6"
OpticPro 4800P override (works if OP600
has been detected) swaps red/green color
.TP
.IR m " = 7"
Primax 4800Direct 30bit override (works if
OP4830 has been detected)
.RE
.PP
See the
.I plustek_pp.conf
file for examples.

.SH "PARALLEL PORT MODES"
.PP
The current driver works best, when the parallel port
has been set to EPP-mode. When detecting any other
mode such as ECP or PS/2 the driver tries to set to a
faster, supported mode. If this fails, it will use the
SPP mode, as this mode should work with all Linux supported
parallel ports. If in doubt, enter your BIOS and set it to
any mode except ECP.
.PP
Former Plustek scanner models (4830, 9630) supplied a
ISA parallel port adapter card. This card is
.BR not
supported by the driver.
.PP
The ASIC 96001/3 based models have sometimes trouble with
high resolution modes. If you encounter sporadic corrupted
images (parts duplicated or shifted horizontally) kill all
other applications before scanning and (if sufficient
memory available) disable swapping.
.PP
See the
.I plustek_pp.conf
file for examples.
.PP
.SH FILES
.TP
.I @CONFIGDIR@/plustek_pp.conf
The backend configuration file
.TP
.I @LIBDIR@/libsane\-plustek_pp.a
The static library implementing this backend.
.TP
.I @LIBDIR@/libsane\-plustek_pp.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. On *NIX systems, 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
.IR @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
.IR "tmp/config" ,
.IR "." ,
and
.I "@CONFIGDIR@"
being searched (in this order).
.TP
.B SANE_DEBUG_PLUSTEK_PP
If the library was compiled with debug support enabled, this
environment variable controls the debug level for this backend. Higher
debug levels increase the verbosity of the output.
Example:
export SANE_DEBUG_PLUSTEK_PP=10
.SH "SEE ALSO"
.BR sane (7),
.BR xscanimage (1),
.br
.I @DOCDIR@/plustek/Plustek\-PARPORT.changes
.SH "CONTACT AND BUG-REPORTS"
Please send any information and bug-reports to:
.br
.B SANE Mailing List
.PP
Additional info and hints can be obtained from our
.br
Mailing-List archive at:
.br
.I http://www.sane\-project.org/mailing\-lists.html
.PP
To obtain debug messages from the backend, please set the
environment-variable
.B SANE_DEBUG_PLUSTEK_PP
before calling your favorite scan-frontend (i.e.
.BR xscanimage (1)), i.e.:
.br
.I export SANE_DEBUG_PLUSTEK_PP=20 ; xscanimage
.PP
The value controls the verbosity of the backend.

.SH "KNOWN BUGS & RESTRICTIONS"
.PP
* The Halftoning works, but the quality is poor
.PP
* Printers (especially HP models) will start to
print during scanning. This in fact is a problem
to other printers too, using bidirectional protocol
(see www.plustek.com (TAIWAN) page for further details)
.PP
* The driver does not support these manic scalings up
to 16 times the physical resolution. The only scaling
is done on resolutions between the physical resolution
of the CCD-sensor and the stepper motor i.e. you have a
600x1200 dpi scanner and you are scanning using 800dpi,
so scaling is necessary, because the sensor only delivers
600dpi but the motor is capable to perform 800dpi steps.
.PP
* On some devices, the pictures seems bluish
.PP
.I ASIC 98001 based models:
.PP
* The 300dpi transparency and negative mode does not work
correctly.
.PP
* There is currently no way to distinguish a model with
and without transparency unit.
.PP
* The scanned images seem to be too dark (P9636T)
.PP
.I ASIC 96003/1 based models:
.PP
* 30bit mode is currently not supported.
.PP
* On low end systems under heavy system load the
driver may lose data, which can result in picture
corruption or cause the sensor to hit the scan bed.
.PP
* The scanning speed on 600x1200 dpi models is slow.
.PP
* The scanning quality of the A3I is poor.
