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.

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.

651Feature RequestSony UP-D printersbrightness/contrast, etc on the UP-D898 familyNew2020-12-02 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.

649TODOShinko CHC-S6145/S2245Support the Kodak 6900 and HiTi M610Requires testing2020-08-27 Task Description

The Kodak 6900 is actually the CHC-S2245-6A

HiTi M610 is also a rebadged S2245

We have the USB VID/PIDs already; just need a printer to test with.

641TODOCommon CodeRewrite README into more structured ocumentationNew2020-03-05 Task Description

I'd like to use this as an opportunity to learn ReStructuredText, and the Sphinx documentation system.

How far I take this is another matter..

639TODOHiTi familyAdd job combining support for HiTi familyNew2020-01-22 Task Description

P520/P525 and P720/P750

3.5x5 -> 7x5

4x6 -> 8x6

Combined size is slightly smaller (4 and 23 rows respectively) so we'd have to trim the ends off. Not a big deal.

While I have a P520 printer, I don't have the necessary media to test this.

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.

634Feature RequestShinko CHC-S6245/ Kodak 8810Support Panorama sizes on EK8810New2020-02-27 Task Description

EK8810 in the APEX system supports 8x18/8x26 and 8x22/8x32 sizes (plus 8x14/16/20/36?)

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

633Feature RequestDNP/CitizenSupport Panorama on DS620 and DS820 familiesResearching2021-01-17 Task Description

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

632Feature RequestMitsubishi CP-Dxx familySupport Panorama on CP-D90DW familyRequires testing2021-01-17 Task Description

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

630TODOCanon Selphy CP/ESInvestigate port 59223 on wifi-enabled Selphy modelsResearching2020-02-27 Task Description

On CP900, CP910, CP1200, and CP1300, a telnet interface is present on port 59223. Upon connecting, it prompts for an unknown password.

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

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

613Feature RequestMitsubishi CP-Dxx familyFigure out how to pipeline jobs with D70 familyNew2020-08-20 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..

608TODOCommon CodeMake Gutenprint more cross-compile friendlyNew2020-03-27 Task Description

The problem is that, at compile time, we rely on some host-compiled stuff to generate data files and whatnot. We need to compile the same stuff for the target.

I wonder if it may be worth moving to a more unified Make environment..

592Feature RequestSony UP-D printersInvestigate Sony UPCX1New2019-03-26 Task Description

300 dpi, 4" or 5" wide media.

Not sure if it uses sheet or roll media.

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

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

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.

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

I have a P120i that is in perfect working order.

580Bug ReportCanon Selphy CP/ESDetect when on battery power and handle it gracefullyNew2017-04-11 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...

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?

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..)

568TODOMitsubishi CP-Dxx familyFigure out how to set the "user string" that's supposed...New2017-03-23 Task Description

There's a proper serial number returned so that's not so critical.

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..

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

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.

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.

556Feature RequestSony UP-D printersstatus queries and flow controlResearching2020-11-24 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.

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.

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.

533TODOShinko CHC-S6245/ Kodak 8810Verify support for S6245 (and HiTi P910L)Requires testing2020-03-27 Task Description

Code complete, but needs testing.

521Feature RequestHiTi familyInvestigate HiTi 510L, P530D, P310W, X610, and others?Waiting on Customer2020-12-02 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

P110 series has a binary-only driver

There are also other unknown variations, P518A, P728, P310L.

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.

505TODOOther printersVerify support for Mitsubishi CP3020D/DA printersRequires testing2019-12-26 Task Description

Experimental support is in gutenprint, but this needs testing.

502TODOOther printersVerify support for Kodak 8500 and 9810/8800.Requires testing2016-08-18 Task Description

The 8500 is a rebadged Mitsubishi CP3020, but the 9810 and 8800 is unique.

Both need sniffs to determine if they need an intelligent spooler.

500TODOOther printersInvestigate Shinko S8145New2019-05-23 Task Description

The T1/S8145 is a fancy "silver foil" thingey with two print heads.
