 ***************************************************************************

  This intelligent backend is needed to utilize many common dye-sublimation
  photo printers under Linux, OSX, and other UNIX-like operating systems.

  Although these printers advertise themselves as standard USB Printer Class
  devices, they do not actually obey those specifications and require
  special two-way handshaking in order to successfully print.

  This backend can only be used in conjunction with Gutenprint 5.2.10 or
  newer. Please see the Gutenprint README file (section II D) for more
  information on use of this backend and integration into CUPS.

  While this repository is considered the canonical upstream source for
  this code, code snapshots are bundled with each Gutenprint release.
  Generally speaking, the code in this repository will require the current
  Gutenprint release (or pre-release) to generate the actual print jobs.

  As such, when compared to any given Gutenprint release, the code found
  here is usually newer, with additional features, device support, and
  bugfixes.  At the same time, it may have half-developed features that
  don't quite work, with giant bugs that come out at midnight to eat
  your cat.

  With few exceptions, all printer support in selphy_print (and Gutenprint)
  was developed without any assistance from the printer manufactuers,
  relying on reverse-engineering and a great deal of experimentation.

  On that note, please keep in mind that this software distributed
  in the hope that it will be useful, but WITHOUT ANY WARRANTY WHATSOEVER.

 ***************************************************************************

  This backend also supports a "standalone" mode that performs various
  utility functions for most models, such as querying status and
  configuring parameters. The exact commands supported for each
  printer are documented below.

 ***************************************************************************
  Compilation:

     This tool requires libusb 1.0 to build.  We highly recommend
     v1.0.16 or newer due to general stability improvements. Versions
     older than 1.0.10 will require -DLIBUSB_PRE_1_0_10 to be defined
     (see the Makefile).

     To further complicate things, libusb-1.0 had a temporary fork called
     libusbx, but that was merged back into libusb as of v1.0.18.
     Consequently, your distribution package for libusb-1.0 may be
     called libusbx instead.

     Additionally, you will need the CUPS development packages installed,
     so we can figure out how the local CUPS instance is configured.

     Lastly, in order to integrate the backend into an existing Gutenprint
     installation you will need to install the Gutenprint development
     headers.

     Fedora/RedHat:
	yum install libusbx-devel libusb1-devel cups-devel gutenprint-devel
     Debian/Ubuntu
	apt-get install libusbx-dev libusb-1.0-0-dev libcups2-dev gutenprint-dev

   All you need to do after that is type 'make'

 ***************************************************************************
  CUPS backend usage:

   DEVICE_URI=someuri \
       gutenprint52+usb job-id user title num-copies options [ filename ]

    The backend generates output for CUPS to parse, including logging
    print counts, and if the printer supports it, reporting media type and
    remaining media counts.

    Please note that this backend merely handles the low-level
    communication with the printer!  Actually generating print jobs requires
    use of Gutenprint compiled with support for CUPS.

   DEVICE_URI=someuri FINAL_CONTENT_TYPE=application/vnd.cups-command \
       gutenprint52+usb job-id user title num-copies options [ filename ]

    This parses a CUPS command file and performs actions listed in the file.

     Implemented commands:

       ReportLevels        Report the marker (ie media) type and levels.

     Other commands may be implemented in the future.  Individual printer
     models may not implement these commands.

  Other Notes:

    'someuri' is the URI returned by the backend when it probes for supported
    devices.  is invoked by calling the backend with no arguments.

    The backend supports multiple URI schemes.  First, the "modern" one:

     gutenprint53+usb://backendname/serialnum

    And the old/legacy/classic one:

     gutenprint52+usb://manufacturer/model/?backend=backendname&serial=serialnum

    The URI scheme generated at device probing depends on the version of
    gutenprint installed.  By default, the modern scheme is used when compiled
    against Gutenprint 5.3 or newer, and the legacy scheme is used with
    Gutenprint 5.2.

    Regardless of the scheme generated at probe time, the backend will continue
    to detect and parse both schemes indefinitely as to not break backwards
    compatibility with existing deployments.  To manually switch the URI
    scheme type generated at runtime, set the OLD_URI_SCHEME environment
    variable to either 0 or 1, as appropriate.

***************************************************************************
  Standalone usage:

    This backend is set up as a multi-call executable; that is to say
    behaivor changes based on the name used to invoke the executable.
    When compiled, a set of symlinks are created, corresponding to the generic
    name of each of the internal backends.  Alternatively you may set
    the BACKEND environment variable to force a specific backend to be used.
    These commands are equivalent:

         BACKEND=backend ./gutenprint52+usb [ arguments ]
	 ./backend [ arguments ]

    The 'backend' name is any one of the names listed when invoking the
    executable with no arguments.  For example:

       ./dnpds40
       DEBUG: Multi-Call Dye-sublimation CUPS Backend version 0.88
       [ ... ]
       DEBUG: Standalone DNP DS-series / Citizen C-series backend version 0.106
       DEBUG:   supporting: dnp_citizen dnpds40 dnpds80 dnpds80dx dnpds620 dnpds820 dnprx1 citizencw01 citizencw02 citizencx02
       [ ... ]

     The first entry after 'supporting' is the generic backend name, while
     the others correspond to specific models the backend supports.  Any one
     can be used as the 'backend' name.

     All backends support the following invocations:

        backend [ arguments ]
	backend [ arguments ] filename
	backend [ arguments ] - < filename
	somecommand | backend [ arguments ] -

      The 'filename' here refers to the raw spool data generated by
      Gutenprint (eg via its gimp plugin) or the Windows print-to-file
      output.

      All global arguments:

	   -D                 Increment debug level                      [1]
	   -G                 Display GPL text
	   -f                 Enable fast return mode if possible        [2]
	   -d numcopies       Print 'numcopies' of the supplied job
	   -v                 Silence all output except for warnings/errors

       [1]  This argument can be repeated to increase the debug level.
            Alternatively, the 'DYESUB_DEBUG' environment variable can be
	    used.  For example, '-DDD' and 'DYESUB_DEBUG=3' are equivalent.

		DYESUB_DEBUG=1		Enable debug output
		DYESUB_DEBUG=2		Dump contents of short messges
		DYESUB_DEBUG=3		Dump contents of all messages

       [2]  This terminates the backend as soon as the printer has
	    accepted the print job, without waiting for the print job
	    to complete.  Not all printers support this feature. This
	    can also be enabled by setting the 'FAST_RETURN' environment
	    variable.  This is the default behavior when using this backend
	    with CUPS.

      Finally, some backends support additional arguments; see their details
      below.

 ***************************************************************************
  Other Environment Variables:

      If you have multiple models of the same printer family connected
      simultaneously, the backend will choose the first one it finds.
      If you wish to target a specific device, you may specify its
      serial number using the 'SERIAL' environment variable. For example:

            SERIAL=N782 backend filename [ arguments ]

       All backends support an additional operational mode, to test out
       unknown models. To use this mode, specify the VID, PID and its
       internal device type as environment variables:

            EXTRA_VID=04a9 EXTRA_PID=3ab1 EXTRA_TYPE=7 backend filename

       The VID and PID are specified in hexidecimal, and the TYPE is
       the P_XXX enumeration defined in backend_common.h. The '7' in this
       example corresponds to most Canon SELPHY CP models, and is what you
       would use if you were trying to get the backend to detect an
       otherwise unrecognized SELPHY CP model.

       If you are able to successfuly print using this technique,
       please let us know so we can add the apppriate entry to the
       internal database.

       For debugging USB operation, there following environment variables
       can be set:

           MAX_XFER_SIZE     Maximum transfer size, in bytes.
	   XFER_TIMEOUT      Timeout, in milliseconds, for all USB operations

         for example:

           MAX_XFER_SIZE=32768 XFER_TIMEOUT=30000 backend filename

       Finally, BACKEND_QUIET can be set to a non-zero value to silence all
       output other than warnings and errors.

   *** VERY IMPORTANT ***

     In order to generate usable output, the Sinfonia CHC-S6145 printer
     (and its siblings listed above) require the input data to be
     transformed using specific image processing algorithms.

     The library that implements this processing is dynamically loaded
     at runtime. There are three options:

       * libS6145ImageProcess -- Supported by Sinfonia, this is a proprietary
         library only available for x86 and x86_64 linux targets. It can be
	 obtained by politely contacting your local Sinfonia distributor.

         If you have the appropriate permission fron Sinfonia and its
	 technical and legal limitations are acceptible to you, we recommend
         you use the supported libS6145ImageProcess library, as it will
	 generate the highest quality output.

       * libS6145ImageReProcess -- GPL'd re-implementation of the Sinfonia
         algorithms, available as source.  It is a drop-in replacement
	 that appears to generate identical output to the proprietary
	 Sinfonia library.

	 DISCLAIMER: Sinfonia Inc was not involved in the creation of
	 libS6145ImageReProcess and is not responsible in any way for any
	 deficiencies in its output. They will provide no support if it is
	 used.

         Do *NOT* contact Sinfonia for support if you are using
	 libS6146ImageReProcess!

	    (Please see the full disclaimer in libS6145ImageReProcess.c)

       * If neither of the above libraries are found, the backend will
         fall back to a very crude algorithm that generates low-quality
	 results not suitable for photographic output

     As selphy_print is released under the terms of the GPL, it cannot
     normally be combined with proprietary libraries.

     Therefore, the authors of selphy_print grant its users an additional
     permission (under section 7 of the GPLv3) to combine and/or redistribute
     it with the libS6145ImageProcess library.  For the full text of this
     license exception, please see the header of backend_shinkos6145.c

  Notes:

    [1]  **** VERY IMPORTANT ****

    The CP-98xx family is similar to the CP-D70 family in that it requires
    the input data to be gamma corrected (and likely transformed in other
    ways) before it is sent to the printer.

    Unlike the D70 family, the data tables used are embedded into the driver
    instead of being bundled separately, further complicating the process
    of figuring out how everything works.  Some progress has been made,
    allowing for proper gamma correction/linearization to at least generate
    usable prints, although the quality is not considered up to par.
