666 | Feature Request | Other printers | Support Kodak D4600 | Requires testing | 2023-10-01 |
Task Description
This is a rebadged version of the Mitsubishi CP-W5000. It likely has a unique USB VID/PID but it may also require tweaks to the command stream. Until someone pops up with one of these, it's not going to happen. |
|
611 | Feature Request | Other printers | Support Kodak 6900 (aka HiTi M610 / X610) | Closed | 2019-05-13 |
Task Description
The Kodak 6900 looks to be a rebadged HiTi M610, which itself is closely related to the X610.
Figure out the spool format to get preliminary support! |
|
674 | Feature Request | Other printers | Support iDRPT 4x6 printer (Zeva 1966) | New | 2023-09-27 |
Task Description
4x6, sheet fed, has USB port. |
|
668 | Feature Request | DNP/Citizen | Support Fujifilm ASK-400 | Waiting on Customer | 2023-12-31 |
Task Description
Appears to be a rebadged Citizen CX-02 / DNP DS620 Main questions are what the VID/PID/IEEE1284 IDs are, and what firmware features were stripped out vs the other models. (Eg rewind support, partial matte, and more) |
|
602 | Feature Request | Common Code | Support combining print jobs | Closed | 2020-01-22 |
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. |
|
625 | Feature Request | Shinko CHC-S6245/ Kodak 8810 | Support and Custom sizes and cuts on EK8810 | Closed | 2019-12-12 |
Task Description
EK8810 supports arbitrary print sizes (up to media max) and full cutter control. See if it's feasible to export "custom" sizes, asymmetric sizes (eg 8x6+8x4 on 8x10 media), and maybe even allow the cutter to be directly controlled. |
|
556 | Feature Request | Sony UP-D printers | status queries and flow control | Researching | 2021-08-15 |
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. |
|
573 | Feature Request | Shinko CHC-S6145/S2245 | S6145: Have Gutenprint generate planar YMC directly | Closed | 2019-08-13 |
Task Description
That way the backend won't have to do the conversion, saving some processing overhead.
(Re-purpose an unused field in the header, and clear it afterwards. Not unlike how the D70 backend does it!) |
|
574 | TODO | Other printers | S6145 -- don't generate an OC layer if not needed | Closed | 2017-03-30 |
Task Description
And don't bother sending it over unless it's a matte print.
Actually I think the library already handles this okay, but we still have to allocate the space and generate things regardless. A waste of CPU cycles, but otherwise harmless. Probably not worth doing without direct access. |
|
476 | Bug Report | Shinko CHC-S2145 | s2145 hangs on subsequent requests | Closed | 2013-07-16 |
Task Description
The first request succeeds, but subsequent requests hang when trying to talk to the printer. I suspect what's going on here is that the response buffers we're posting are simply too small and the printer loses its mind. |
|
641 | TODO | Common Code | Rewrite README into more structured ocumentation | New | 2020-03-05 |

|
530 | Feature Request | Mitsubishi CP-Dxx family | Reverse-engineer color scaling/dithering algorithm | Closed | 2016-10-07 |
Task Description
Mitsubishi CP-D70, D707, K60, D80, and their siblings (Kodak 305, Fuji ASK300) all rely on the driver to dither/scale their output data based on an unknown algorithm.
Figure out what this is, so that these printers can be properly supported. |
|
627 | Feature Request | DNP/Citizen | Report media type for DS820 in CUPS marker messages | Closed | 2019-09-22 |
Task Description
There are two medias, SD and PP. We should report this (along with the size) in the marker message.
Additionally, the DS40/620/820 support a variety of "luxury" medias. Figure out if we can detect this in software, and report that too.. |
|
588 | Bug Report | Magicard family | Registration/Alignment issue with Black plane | New | 2018-01-04 |
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. |
|
518 | Feature Request | Canon Selphy CP/ES | Recover from Error conditions (ES models) | Closed | 2014-03-12 |
Task Description
There's a special command the driver sends to clear the printer's error state. We know this for the CP-series, but none of the ES-series. The backend supports this just fine now, but we don't know how the ES models recover. |
|
657 | Feature Request | Mitsubishi CP-Dxx family | Query and set vertical calibration | Assigned | 2021-05-16 |
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) |
|

Task Description
It's most obvious when printing something with a deep black; you'll see it bleed past a bit.
It's worse in Fine, better in SuperFine/UltraFine.
|
|
559 | TODO | Common Code | Pull copy generation out of backend | Closed | 2017-11-09 |
Task Description
Gutenprint 5.2.12 now supports generating multiple copies. The backend shouldn't do it internally (nor should it print hte PAGE output)
* Printers that have a copy count in the job header -- use the printjob number if it's >= the cmdline copy one.
* Otherwise, backend should loop and generate copies.
* If *not* invoked from within CUPS, print the PAGE output. |
|
523 | Feature Request | Common Code | Proper media/ribbon status messages | Closed | 2016-08-21 |
Task Description
CUPS has a standard reporting mechanism for attributes, including media/ribbon/etc levels. The general syntax is:
ATTR: foo=bar[,baz,etc]
There's also the notion of state that can be reported in a unified manner:
STATE: +media-empty [reasontext]
STATE: -media-empty
So:
1) Altering backends to report media empty using this mechanism
2) Alter backends to report remaining media, if known, using this mechanism.

652 | Feature Request | Sony UP-D printers | Print combining for UP-DR200 | New | 2020-12-02 |
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. |
|
560 | Bug Report | Mitsubishi MedSci | P95: Failure to parse printjob when 'clear memory' is e ... | Closed | 2017-02-12 |
Task Description
The problem is that two commands of different length use the same 2-byte prefix. To distinguish between them we'll need to read the third byte, but only in that case as there are some commands that are only 2 bytes.
Or re-architect the command parser to handle this without extra hacks. |

664 | Bug Report | HiTi family | P525 1.28 firmware "doesn't print" | Closed | 2023-03-20 |
Task Description
User report. Claims it works on older fw, but unable to report the precise version that works vs doesn't. Supposedly using recent-ish selphy_print, unknown version. Need to update P520L printer to this FW and see what happens. |
|
525 | Bug Report | Mitsubishi CP-Dxx family | Output on CP-D70 is way too dark | Closed | 2015-07-23 |
Task Description
This suggests we need to apply a correction curve to the raw 16-bit data sent to the printer. Uncertain if user was using the ICC profile. Unfortunately it'll probably take some careful analysis of printing calibration targets to come up with an appropriate correction factor. |
