[Gimp-print-devel] Printer Drivers for printers not on the list

[Claus Pfisterer]

Hello

I searched for printer drivers which i could install on a raspberry pi to use with one these two printers. when i looked for printer drivers from the manufacturer, i realized that they only support windows and mac.

is there a way to find a solution for these two printers?

Hello Claus,
I assume both of these are dye-sublimation printers?
You are in luck, a pre-release of 5.2.10 has just been made available,
and the Mitsubishi is experimentally supported (extracts from the NEWS
file below).
So testing is most welcome!

The Sony one is not currently know, so perhaps that can be supported
if you can send the requisite printjobs and be available for testing?

Known Sony dye-sub printers:
- Sony Dye-Sublimation printers:

Sony UP-DR150

Support for the Sony UP-DR150 was greatly improved through the
addition of an intelligent CUPS backend.

Sony UP-DR200

The Sony UP-DR200 requires the use of an intelligent CUPS backend.

http://www.graphicart.ch/de/produkt/197/mitsubishi-cp-d70dw

Known Mitsubishi dye-sub printers:
- Mitsubishi Dye-Sublimation printers:

Mitsubishi CP9810D/DW

This model has been verified to work

Mitsubishi CP3020D/DU/DE (EXPERIMENTAL)
Mitsubishi CP3020DA/DAE (EXPERIMENTAL)
Mitsubishi CP9550D/DW (EXPERIMENTAL)
Mitsubishi CPD70D/DW (EXPERIMENTAL)
Mitsubishi CPD707D/DW (EXPERIMENTAL)
Mitsubishi CPK60DW (EXPERIMENTAL)
Mitsubishi CP3800DW (EXPERIMENTAL)

None of these models have been tested and confirmed to work
(or not), so feedback is welcome.

NOTE: With the exception of the CP-K60DW-S, all Mitsubishi
printers with red faceplates and/or model designations ending with
an '-S' suffix are not supported.

The CP-D70DW and CP-D707DW (and likely the CP-K60DW) require use of
an intelligent backend, which is bundled with Gutenprint.

As Gernot has already mentioned, this isn't supported at all, but it's
possible it's similar to one of the other supported models. Please
contact me off-list and we can try to figure out what it will take to
get this model supporable.

The good news is that this printer *should* work with the upcoming
5.2.10 release. The bad news is that it requires an intelligent
backend, and while one has been written, it hasn't received any testing
at all.

So, if you are willing to do some testing for us, and have the ability
to compile stuff for/on the RPi, please contact me off-list and we can
ensure the final 5.2.10 release works properly with the CP-D70/D707
printers.

I did a little digging last night, and I think this (and the DNP
SL-10) should be straightforward to support. Their printjob is
structured similar to the UP-DR150/DR200, and the existing UP-DR150
backend will probably work too.

With access to the printer, I can probably make this work in time for
the 5.2.10 release.

(As an aside, the UP-CR20L and the DNP SL-20 are radically different,
apparently using a variation of HP PJL. I don't know if the printer
actually expects this stream as-is)

I just need to confirm that the backend works.

I just need to confirm that the backend works.

I recently got hold of a Mitsubishi CP-D70DW on loan and can confirm that I
can print to it using 5.2.10-pre2. The colors are off, though. Yellow seems
ok but Cyan Magenta and Black are dark enough to make photographs
unrecognizable. Have tried adjusting the advanced settings but I really
don't know what I'm doing so I just end up printing lots of junk. Any tips
for calibrating it? Thanks!

I made a pile of changes after -pre2 was released, but they should only
affect paper sizes and lamination. Any chance you could try the current
CVS code?

I'm not sure why one color would be good but not the others, but this
should be relatively straightforward to test.

Can you send me a photo of the output next to some sort of reference of
what it should look like? Or better yet, print out some sort of color
test target (eg Loading Image...)?

Thanks,

I pulled the latest code from CVS (well, as of 2 days ago) and here's a
side-by-side scan with Windows on the left:
Loading Image...

The artifacts at the top, bottom and right are from tape I used to stick it
to the same piece of paper while the splotches over dark area of the Linux
print actually do appear in the printout.

Thanks for looking at this!

https://dl.dropboxusercontent.com/u/93068/WindowsLeftGutenprintRight.jpg

At first glance it would appear that the input data and the printer
need different linearization/gamma curves.

I'm guessing you're not using an ICC profile for the printer under
Linux -- and I want to eliminate this as the source of problems before
anything else.

So, grab the Printer's ICC files out of your Windows installation, or
from here:

http://git.shaftnet.org/cgit/selphy_print.git/tree/icm/Mitsu_CP-D70x

The three files correspond to STandard, UltraFine, or SuperFine modes.
(I'm guessing you're using STandard for these prints)

If you're using a Linux distro that lets you assign color profiles to
your printers, associate it and re-print. Otherwise, you'll
need to convert the underlying image before printing:

convert source.png -profile sRGB.icm -profile CPD70_ST.icc out.png

And then print 'out.png' instead.

Let me know how that looks!

Unfortunately the output looks identical. I'm hoping I did something wrong
here..

I didn't seem to have an sRGB.icm lying around so I used
sRGB_IEC61966-2-1_black_scaled.icc from
http://www.color.org/srgbprofiles.xalter

Also, I used the default Ubuntu 12.04.4 image viewer (Eye of GNOME I
believe) to command the print.

Any ideas? Thanks!

Steven

Sorry about the delay in getting back to you; I thought I'd already
responded.

I'm not sure if that was the right thing to use, but in the end, I don't
think it would have mattered.

IIRC Ubuntu 12.04 doesn't have an ICC-managed printing stack, so I don't
think it's Ubuntu specifically screwing things up here.

I'm guessing we're going to need to implement some sort of color curve
for the Mitsubishi printers inside of Gutenprint. Right now it's
linear, and that's clearly no good. The complication is figuring out
what the curve should be, and that's going to require a fair amount of
trial and error, preferably with a coloriometer.

At this point I'm not sure where to go next. I'm trying to get my hands
on a D70/D707/K60, but that's not likely to happen anytime soon.

Oh, one other question -- When you printed, did you select matte finish?
If you did, can you repeat it without it and tell me if the printer
generated a glossy print?

Thanks,

- Solomon
