.SH NAME
sane\-pixma \- SANE backend for Canon Multi-Function Printers and CanoScan Scanners
.SH DESCRIPTION
The
.B sane\-pixma
library implements a SANE (Scanner Access Now Easy) backend that provides
access to Canon PIXMA / i-SENSYS / imageCLASS / imageRUNNER multi-function
devices (All-in-one printers) and the Canon CanoScan Flatbed/TPU scanners.
The backend implements both the USB interface and network interface 
(using Canon's BJNP and MFNP protocols). The network interface supports scanners 
over IPv4 as well as IPv6 (MFNP over IPv6 is untested).
.PP
Currently, the following models work with this backend:

The device name for USB devices is in the form pixma:xxxxyyyy_zzzzz
where x, y and z are vendor ID, product ID and serial number respectively.
.PP 
Example: pixma:04A91709_123456 is a MP150.
.PP
Device names for BJNP/MFNP devices is in the form pixma:aaaa_bbbbb
where aaaa is the scanners model and bbbb is the hostname or ip-adress.
.PP
Example: pixma:MF4800_192.168.1.45 is a MF4800 Series multi-function peripheral.
.PP
This backend, based on cloning original Canon drivers protocols, is in 
a production stage. Designed has been carried out without any applicable
manufacturer documentation, probably never available. However, we have tested 
it as well as we could, but it may not work in all situations. You will find 
an up-to-date status at the project homepage. (See below). 
Users feedback is essential to help improve features and performances. 
.SH OPTIONS
Besides "well-known" options (e.g. resolution, mode etc.) pixma backend also
provides the following
\#.B experimental
options for button handling, i.e. the options might change in the future.
.br
The button status can be polled i.e. with 'scanimage \-A'.
.br
Button scan is disabled on MAC OS X due to darwin libusb not handling
timeouts in usb interrupt reads, but may work when using the network protocol.
.TP
.I button\-controlled
This option can be used by applications (like
.BR scanadf (1)
and
.BR scanimage (1))
in batch mode, for example when you want to scan many photos or
multiple-page documents. If it is enabled (i.e. is set to true or yes), the
backend waits before every scan until the user presses the "SCAN" button
(for MP150) or the color-scan button (for other models). Just put the
first page in the scanner, press the button, then the next page, press
the button and so on. When you finished, press the gray-scan button. (For
MP150 you have to stop the frontend by pressing Ctrl-C for example.)
.TP
.I button\-update (deprecated)
(write only) In the past this option was required to be set to force 
reading of the button status for
.I button\-1
and
.I button\-2.
The 
.B sane\-pixma
no longer requires this option to be used: if no fresh data is available, it 
will be now requested automatically from the scanner. This option is left for 
backward compatibility reasons.
.TP
.I button\-1 button\-2
(read only) These options will return the value of the respective buttons.
value 0 means that the button was not pressed, 1 is returned when the button 
was pressed. Some scanners with more than two buttons send the button number
as target.
.TP
.I original
(read only) Returns the value of the type or size of original to be scanned
if the scanner provides that data. Known values of type: 1 = document, 2 = foto,
5 = film. Known values of size: 1 = A4, 2 = Letter, 8 = 10x15, 9 = 13x18, b = auto.
Not all scanners can provide this data.
.TP
.I target
(read only) Returns the value of the target of the scan operation if the scanner
provides that data. The values depend on the scanner type. Known values:
1 = save to disk, 2 = save to pdf, 3 = send to email, 4 = send to application
or 1 = JPEG, 2 = TIFF, 3 = PDF, 4 = Compact PDF. For some scanners this value
is equivalent to the number of the pressed button. Not all scanners can provide
this data.
.TP
.I scan-resolution
(read only) Returns the resolution of the scan operation if the scanner
provides that data. Known values: 1 = 75 dpi, 2 = 150 dpi, 3 = 300 dpi,
4 = 600 dpi. Not all scanners can provide this data.
.SH FILES
.TP
.I @LIBDIR@/libsane\-pixma.a
The static library implementing this backend.
.TP
.I @LIBDIR@/libsane\-pixma.so
The shared library implementing this backend (present on systems that
support dynamic loading).
.TP
.I @CONFIGDIR@/pixma.conf
The backend configuration file (see also description of
.B SANE_CONFIG_DIR
below). The files contains an optional list of networked scanners. Normally 
only scanners that can not be auto-detected because they are on a different 
subnet shall be listed here. If your OS does not allow enumeration of 
interfaces (i.e. it does not support the getifaddrs() function) you may need 
to add your scanner here as well.
.PP
Scanners shall be listed as:
.PP
.RS
.I <method>://<host>[:port] 
.RE
.RS
.PP
where method indicates the protocol used (bjnp is used for inkjet multi-functionals
and mfnp is used for laser multi-functionals).
.PP
host is the hostname or IP address of the scanner, e.g. bjnp://10.0.1.4 
for IPv4, bjnp://[2001:888:118e:18e2:21e:8fff:fe36:b64a] for a literal 
IPv6-address or bjnp://myscanner.mydomain.org for a hostname.
.PP
The port number is optional and in normally implied by the method.
Port 8610 is the standard port for mfnp, 8612 for bjnp.
.PP
Define each scanner on a new line.
.SH USB SUPPORT
USB scanners will be auto-detected and require no configuration.
.SH NETWORKING SUPPORT
The pixma backend supports network scanners using the so called Canon BJNP 
protocol and MFNP protocol. Both IPv4 and IPv6 are supported, but IPv6 is as
yet untested with MFNP. Please report your results on the mailing list.
.PP
Configuration is normally not required.
The pixma backend will auto-detect your scanner if it is within
the same subnet as your computer if your OS does support this.
.PP
If your scanner can not be auto-detected, you can add it to the pixma 
configuration file (see above).
.SH FIREWALLING FOR NETWORKED SCANNERS
The sane pixma backend communicates with port 8610 for MFNP or port 8612 
for BJNP on the scanner. So
you will have to allow outgoing traffic TO port 8610 or 8612 on the 
common subnet for scanning.
.PP
Scanner detection is slightly more complicated. The pixma backend sends
a broadcast on all direct connected subnets it can find (provided your OS 
allows for enumeration of all netowrk interfaces). The broadcast is sent FROM 
port 8612 TO port 8610 or 8612 on the broadcast address of each interface.
The outgoing packets will be allowed by the rule described above.
.PP
Responses from the scanner are sent back to the computer TO port 8612.
Connection tracking however does not see a match as the response does not come
from the broadcast address but from the scanners own address.
For automatic detection of your scanner, you will therefore have to allow 
incoming packets TO port 8612 on your computer. This applies to both MFNP and
BJNP.
.PP
So in short: open the firewall for all traffic from your computer to port 
8610 (for MFNP) or 8612 (for BJNP)
AND to port 8612 (for both BJNP and MFNP) to your computer.
.PP
With the firewall rules above there is no need to add the scanner to the
pixma.conf file, unless the scanner is on a network that is not directly
connected to your computer.
.SH ENVIRONMENT
.TP
.B SANE_DEBUG_PIXMA
If the library was compiled with debug support enabled, this environment
variable controls the debug level for this backend itself. Higher value increases
the verbosity and includes the information printed at the lower levels.
.RS
0  print nothing (default)
.br
1  print error and warning messages (recommended)
.br
2  print informational messages
.br
3  print debug-level messages
.br
4  print verbose debug-level messages
.br
11 dump USB traffic
.br
21 full dump USB traffic
.br
.RE
.TP
.B SANE_DEBUG_BJNP
If the library was compiled with debug support enabled, this environment
variable controls the debug level for the 
.B BJNP and MFNP
network protocols for this backend. Higher value increases
the verbosity and includes the information printed at the lower levels.
.RS
0 print nothing (default)
.br
1 Print error and warning messages (recommended)
.br
2 Print high level function tracing information
.br 
3 Print more detailed protocol tracing information
.br
4 Print protocol headers
.br
5 Print full protocol contents
.RE
.TP
.B PIXMA_EXPERIMENT
Setting to a non-zero value will enable the support for experimental models.
You should also set SANE_DEBUG_PIXMA to 11.
.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).
