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

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) 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

*** VERY IMPORTANT ***

In order to generate usable output, this family of printers require
the input data to be transformed using specific image processing
algorithms.

The library that implements this processing is dynamically loaded
at runtime. There is currently only one option:

* libMitsuD70ImageReProcess -- GPL'd re-implementation of the
Mitsubishi algorithms, available as source. No guaranteees are
made about its output quality as compared to Mitsubishi's
proprietary drivers, but it is generally considered quite good.

DISCLAIMER: Mitsubishi was not involved in the creation of
libMitsuD70ImageReProcess 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 Mitsubishi for support if you are using
any combination of gutenprint, selphy_print or libMitsuD70ImageReProcess.

(Please see the full disclaimer in libMitsuD70ImageReProcess.c)

Valid commands:

-j Query Job status
-k num Specify standby delay (1-60 minutes, 0 disables)
-s Query printer status
-w Wake up printer
-W Wake up printer (and wait)
-x num Set USB iSerialNumber reporting (1 yes, 0 no) [1]
-X id Cancel print job 'id' [2]

[1] Printer will need to be power-cycled for this to take effect.
[2] Job ID is the Internal Job ID (reported via job status query)

Please note: The CP-D90DW printer does not export a serial number
by default. This means that only one of these can be plugged into
the same system. If you wish to use more than one of these
simultaneously, you must enable the 'iSerial' mode by using the '-x'
command as described below.

Valid commands:

-i Query printer information
-j jobid Query job status [1]
-k num Specify standby delay (1-255 minutes, 0 disables)
-m Query printer media
-s Query printer status
-x num Set USB iSerialNumber reporting (1 yes, 0 no) [2]

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.
