Gutenprint / CUPS Dye-sublimation drivers

This is my personal to-do list for printer-related tasks, encompassing both Gutenprint (http://gimp-print.sf.net) development and CUPS backend work (http://git.shaftnet.org/cgit/selphy_print.git)

580Bug ReportCanon Selphy CP/ESDetect when on battery power and handle it gracefullyNew2021-03-04 Task Description

User reported the CP800 failed to print when on battery power, turns out one of the status fields changed causing us to fail.  I believe that's resovled for the older SELPHY CP models, but the newer ones (including the CP790) and the ES series are likely to have a similar problem.

Not sure what can be done about this without getting the battery and experimenting...

588Bug ReportMagicard familyRegistration/Alignment issue with Black planeNew2018-01-04 Task Description

K extraction appears to work well, but when printing there's a registration problem.  The black layer appears to print several pixels higher than the color layers.

I'm not sure if this is something that needs a fixed offset applied, or is something that can vary printer-printer.

520Feature RequestSony UP-D printersInvestigate Sony UP-CR20L aka DNP SL-20Requires testing2020-11-10 Task Description

Sony sold their printer line to DNP, which rebranded these two models.

Investigate their Spool format, and find out if they need an intelligent backend.

521Feature RequestHiTi familyInvestigate HiTi 510L, P530D, P310W, X610, and others?Waiting on Customer2021-04-19 Task Description

P310W is consumer model; the rest are workhorse kiosk printers.

P530D is a duplexing variant of the P52x series. 

X610 is a tandem printhead high-throughput model that can spit out panoramas over 4 feet long.

P510 series has a binary-only driver but HiTi has provided sources.

aP110 series has a binary-only driver

537Feature RequestOther printersWrite backend for Shinko DP-1045 and Kodak D4000New2019-05-14 Task Description

Aka ColorStream D3

They're the same thing, an 8" wide duplex printer. No support in Gutenprint yet.

548Feature RequestShinko CHC-S6145/S2245Add support for Sinfonia CHC-S6145-5A (aka CS2-c)New2019-06-04 Task Description

It's a card-sized variant of the CS2.  89mm cards of various widths.

556Feature RequestSony UP-D printersstatus queries and flow controlResearching2021-08-15 Task Description

It would be really nice if we could figure out how to query the UP-DR200's printer status, media counts, flow control, etc etc.

557Feature RequestSony UP-D printersInvestigate Sony DPP-FP30New2019-03-26 Task Description

And other members of that consumer printer family.  Not sure if they're still relevant commercially.

565Feature RequestMitsubishi CP9xxx familyCP-9600 family supposedly supports some sort of multicu...New2017-03-23 Task Description

http://www.mitsubishi-photo.cz/drivers/drivers_printers/cz_en/(%20+firmwaredrivers_printers_digi_en.htm

This references a lot of firmware images, including 'Firmware CP9600 for 13x18,10x15(x2),11.5x15(x2).zip -- None of those sizes are covered in the current Gutenprint code.

567Feature RequestMitsubishi CP-Dxx familyFigure out how to query the overall job status on the D...New2017-03-23 Task Description

The command I know about just returns an endless status stream..

569Feature RequestMitsubishi CP9xxx familyFigure out image processing algorithms for CP-98xx fami...Requires testing2020-06-20 Task Description

They're an older-generation of the D70 family's.  Data tables are unfortunately embedded inside the drivers, which makes this a lot more challenging. Sigh.

(If nothing else, simply obtaining the RGB->YMC conversion/gamma tables would make the printers immediately useful..)

572Feature RequestMitsubishi MedSciFigure out how to set printer sharpening on the P95DNew2020-02-27 Task Description

The P93D supports it via the driver, but the P95D doesn't.  However, it can be set on the front panel..  It's in there somewhere, I bet.

Bonus -- Can we enable/disable iserial support?

585Feature RequestZebra printersAdd support for Zebra ID card printers.New2020-03-17 Task Description

I have a P120i that is in perfect working order.

590Feature RequestOther printersInvestigate Kodak D4600 / Mitsubishi CP-W5000New2019-07-08 Task Description

Duplexing 8x12" models, capable of cuts along both axes.

613Feature RequestMitsubishi CP-Dxx familyFigure out how to pipeline jobs with D70 familyNew2021-02-20 Task Description

Right now the backend won't attempt to send anything over if a given deck is printing. However, the printer has 4*num_banks buffers that can be used to pipeline jobs!

So, try to figure out a way to overlap things. We'll have to be smarter about jobids..

624Feature RequestKodak 605/70xxFigure out backprinting on Kodak 7010 and 7015Requires testing2019-09-23 Task Description

No documentation, no driver option, no idea how to drive it

629Feature RequestHiTi familySupport the HiTi CS-2xx card models.New2019-10-05 Task Description

HiTi supplied source code, in an "open source all rights reserved" drop

632Feature RequestMitsubishi CP-Dxx familySupport Panorama on CP-D90DW familyRequires testing2021-07-13 Task Description

Printer supports combining two or three 6x8 prints into 6x14 or 6x20 panoramas. Figure out how to do this.

633Feature RequestDNP/CitizenSupport Panorama on DS620 and DS820 familiesResearching2021-07-13 Task Description

DS620 supports 6x14 and 6x20" prints, and DS820 supports 8x18/8x26 and 8x20/8x32 sizes.

634Feature RequestShinko CHC-S6245/ Kodak 8810Support Panorama sizes on EK8810Requires testing2021-07-13 Task Description

EK8810 in the APEX system supports:

8x14, 8x16, 8x18, 8x20, 8x22, 8x24, 8x32, and 8x36 print sizes.

(8x32, and 8x36 are presumably only available on 8x12 media)

Figure out how to make this happen. And what needs to be done on the overlapping areas.

635Feature RequestMitsubishi CP-Dxx familyFigure out job control / pipelining on D90 & M1New2020-03-05 Task Description

We can tell if the printer is idle or busy, but don't know how to query active jobs, free buffers, and so forth.

651Feature RequestSony UP-D printersbrightness/contrast, etc on the UP-D898 familyNew2021-09-08 Task Description

There's presumably a way to configure this stuff from the host side,  In a FILE output mode the Windows drivers don't allow these settings to be changed, so to make this happen I'll have to obtain sniffs.

652Feature RequestSony UP-D printersPrint combining for UP-DR200New2020-12-02 Task Description

The UP-DR200, under Windows, will automatically combine two 4x6 copies into a single 8x6" print.  I have a sniff of this happening; figure out how it works, and implement in the backend if feasible.

653Feature RequestMitsubishi MedSciImplement Sharpening on the CP9xxx and CP30 printer fam...New2020-12-06 Task Description

I _think_ it's the same algorithm for both.  So use the CP30 to work out what's needed, and test it out.

The library API is already there, so once ready it should just be drop-innable.

Note:  This will also require extracting the data tables from the CP30 driver.

657Feature RequestMitsubishi CP-Dxx familyQuery and set vertical calibrationAssigned2021-05-16 Task Description

A user has a EK305 that cuts about 1mm off.  Mitsubshi's service manuals reference a "Service Tool" that can adjust this calibration (and other things)
