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)

500TODOOther printersInvestigate Shinko S8145Assigned2015-08-26 Task Description

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

520Feature RequestOther printersInvestigate Sony UP-CR20L aka DNP SL-20Assigned2018-12-29 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.

538Feature RequestDNP/CitizenAdd support for DS80DXRequires testing2018-10-02 Task Description

It has all the joy of the DS80, but also supports sheet-fed simplex and duplex operation. It's a veritable mess to support cleanly.

564Bug ReportMitsubishi CP-D70 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.

569Feature RequestMitsubishi CP-9xxx 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..)

585Feature RequestOther printersAdd support for Zebra or other ID card printers.Assigned2017-11-24 Task Description

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.
