CUPS Dyesub Backends

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

535Feature RequestOther printersWrite backend for Kodak 8810 and 7000/7010/7015Assigned2019-05-21 Task Description

The 8810 is also known as a Shinko CHC-S1845-5A.

It appears closer to the S1245 mechanically, but S6245 programically.

The 7000/7010/7015 models are Shinko CHC-S1645-5A/5B/5C, respectively.

Probably not worth wasting any time on unless someone steps up with docs and hardware.

612TODOCommon CodeUnify the various Shinko/Sinfonia backendsAssigned2019-05-14 Task Description

For the most part, the shinko/sinfonia printers are quite similar in how they operate. There are unfortunately differences in specific commands and how some of the fields in the headers are parsed.

So, now that the backend infrastructure is decoupled from the "model name", look into unifying:

  • Sinfonia S2145
  • Sinfonia S6145
  • Sinfonia S6245
  • Kodak 605

These two are different than the others, but close to each other:

  • Sinfonia S1245
  • Kodak 6800/6850

Meanwhile, these new models are likely similar to models in the first set:

  • Sinfonia 2245
  • Kodak 7000/7010/7015
  • Sinfonia 8145
  • Kodak 8810
  • Sinfonia DP-1045
  • Kodak D4000

What I expect to do is that when/if support for one or more of these new models is implemented, it will be bolted onto an existing backend, and that will be the basis for merging in the others.

602Feature RequestCommon CodeSupport combining print jobsAssigned2018-06-21 Task Description

As a way to prevent wasting media, when using 6x8" media, automagically combine consecutive 4x6" jobs to a single 8x6" print and submit that to the printer behind the scenes.

The D90 and Kodak 68xx do this automatically in the printer, and others (eg Mitsu D70 family) do this in the driver.

Extend the backend core to support this generically, and try to add specific support to printers/families that can use this feature.

520Feature RequestSony UP-D printersInvestigate Sony UP-CR20L aka DNP SL-20Requires testing2019-04-21 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.

500TODOOther printersInvestigate Shinko S8145Assigned2019-05-14 Task Description

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

569Feature RequestMitsubishi CP9xxx familyFigure out image processing algorithms for CP-98xx fami...Requires testing2018-06-18 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..)

564Bug ReportMitsubishi CP-Dxx familyD70 fails to print on Raspberry Pi systemsResearching2018-02-26 Task Description

We get failures when sending the printjob to the printer, with libusb reporting USB timeouts at random places.  There seems to be no consistency to when a transfer fails.  Using a hub makes this worse.

I have an additional two reports of a RPi3 failing USB transfers to a D80 when there is no ethernet cable plugged into the interface!

 

The K60/EK305 appears to work okay.
