[darktable-user] Printing

[Anders Lund]

Hello,

I just tried the printing functionality in dt.

First, I did not get presented with printer settings, so I had to set the
printer defaults (using kde systemsettings and system-config-printer in my
case).

The paper size list in the printing section of dt is not matching the list of
papers supported by the printer, and the very common (at least in europe) size
13*18cm is missing.

I wanted to apply a style, and selected one in the list - but it was not
applied.

My printer is an Epson 1500w, and the driver is the one provided by epson (and
recommended by openprinting).

Anyone knows if this part of dt is being worked on?

Kindly,
Anders

Hi,
I just got an Epson printer, and found the printer module to be working fine:

I am using Turboprint, including the printer setup tool, with one of their paper profiles. The colours are fine. Don't know about 13*18, though.

I am wondering if it is possible to print multiple images onto one page. This would be nice to e.g. quickly compare different processing variants of one image.

Cheers
Michael

Hi,

Which printer? And which driver? Is it a turpoprint provided one?

I don't have problems with printer/color quality. The stylus 1500W is a
"proconsumer" grade printer, and there is not direct access to using .icc
files, I believe it handles that internally based on paper choice.

The 13x18 paper can probably be achieved by using a custom paper size.

That is supported by the digikam printing tool, but not tested by me yet, and
not really useful for the described scenario, unless you export your photo

Hi,

it's the xp15000, with the Turboprint driver.
I will try digikam to print multiple images - of course it would be easier to just clone an image in darktable and make it e.g. half a stop lighter, but exporting is not so much more effort.

Cheers

More: I find that the dt printing tool handles margins correctly, as opposed
to the digikam printing tool. That is, with dt I can have a white border on my
prints using margin, I have not been able to achieve that using digikam yet.

As far as I know this is still impossible. This question has been
adressed couple times already, you can search mailing list for "printer
settings" and "printer colors". In my case (Turboprint drivers) I have
to set required settings (like paper type, color profiles) as default
and print from darktable with default settings. Or, which is more
convinient, from Turboprint's Gimp plugin.

Couldn't dt use the system printing dialog? (that could be a gtk one, if such
a thing exists?)

In digikams print creation tool, a dialog is displayed that includes the
printer specific options, using kde/qt ui.

It's better to address this issue to developers, e.g. Pascal Obry.

If you're using TurboPrint then yes there is a dialog displayed where
you can select all options.

Now this is not done for the standard Gtk+ dialog because it is not
possible to get good results if you change random values in the printer
driver like Gutenprint. Currently the color management in CUPS is
disabled (by dt) so all the jobs must be done before. When using
TurboPrint you'll see a message in printer ICC saying:

"color management in printer driver"

So for now I would highly recommend using TurboPrint to get high
quality print with darktable.

I'm not looking for color management, but for the ability to select
- print quality
- paper type
- boarderless on/off
- safe paper size selection (which is also likely simpler than the present
list)

I currently mostly prints with digikam print creator, since that is the
closest. I export my file using ProPhotoRGB profile from dt, and the printer
(or printer driver) handles the color management, likely based on paper type
selection.

I never tried using turboprint, but cups works with the driver provided by
epson, which is producing very good results.

I don't understand why using cups is a problem for dt, since other
applications use it without problems.

Maybe you are a lucky one with a perfect CUPS Gutenprint driver. But
this is very very rare and printing without color management with CUPS
is generally giving very bad (and yes I do mean very bad) results when
it comes to color rendered on paper.

And this is NOT only a GNU/Linux issue. I know nobody printing pictures
without a profile on Photoshop or Lightroom on Windows. Color
management is not an option when you want good quality. Now the
situation is a bit better on Windows where the drivers are more
neutral.

Sadly if you are speaking about https://epson.com/Support/wa00821 then
Epson is not providing drivers for Stylus Pro 3880 on GNU/Linux for
example :) So they are not covering all printers, I don't really know
what is the status of those drivers BTW.

If you are not speaking about this Web site, then Epson is nowhere in
the loop, CUPS and Gutenprint are Open Source and fully indépendant
from Epson. And not a single paper manufacturer are providing ICC for
CUPS Linux drivers.

A sad story, but that's the current state of things!

There is a Gutenprint driver for GNU/Linux (this is not dt specific).
The issue is the color rendering and management not the driver itself.
You can print on almost any printer with CUPS+Gutenprint.

Now the color management is a VERY hard issue and not something we can
do ourself. As I said the paper manufacturer are providing ICC profile
for all theirs papers for Windows and Mac drivers, but not for
GNU/Linux one.

That's why TurboPrint is a good solution, they come with a driver and
color management with a good set of paper.

Hope this clarifies the situation, sorry if I was not clear before.

Hi,

I think the icc profiles could be collected in an online database like dt styles or film development recipes. Probably there will be a need for some quality feedback mechanisms, like user reviews or something, but to my impression there are a quite a number of people out there with profiling hardware that may share their icc profiles.

In my view, the issue is hardware support. E. G. Gutenprint supports only one printer in the current xp range of Epson photo printers. That is understandable, but in this instance turboprint has better support.

Cheers
Michael

No, and that's the whole issue. An ICC profile depends on the paper, the
printer and the driver. That's why the WIndows and Mac ICC are not the
same. And until the paper manufacturer see GNU/Linux as a market there is
no luck.

My older Epson was lucky to have native Linux driver (P50) and that was
a very sad story. AFAIR, it was not actually developed by Epson but
rather subcontractor hired by Epson. It lacked ICC color management,
just paper presets (sure, only for Epson paper), maximum resolution
(available in Windows) was not available and many other marketing
limitations. Though it was capable of decent quality but was never
satisfied with it. Sure, you better try it yourself. If you print more
than 50-100 picture a year it totally worth it, IMO.

AFAICT the epson inkjet driver for my printer is on par with the windows one.
No feature mentioned in the printer documentation is missing, although an
extra application is required for checking ink levels, and initiating cleaning
and nozzle check from the PC. icc support is not available in windows/mac
drivers either, but that is of course a problem if using non-epson papers and/
or inks. However, it does produce nice prints, to my limited understanding.

Then I wonder how you used Photo RGB and Adobe RGB, official drivers
for consumer printers are sRGB calibrated by default and Adobe RGB
option is available only for selected models. Sure it will print
something, but I doubt that color reproduction will be right.

Problem is that (as far as I understand) prorpietary Epson driver
expects printed picture to come in sRGB (unless you are lucky to have
AdobeRGB option in you driver) and if you feed it with AdobeRGB it will
give nothing but a bit desaturated colors. With ProPhoto RGB effect
probably will be more pronounced. Maybe you will find this effect more
pleasing (let's say more "natural" colors), but it has nothing todo
with correct reproduction.

So I installed Turboprint, and got the daemon running. I can now select a
turboprint version of my epson printer in dt.

Turboprint does not provide a paperclass for my semigloss paper, they suggest
glossy, but recommends a specific profile, that they will sell (which is fine,
when I get decide on some media to work on).

Bu I still do not get to configure printer settings, like quality and optional
borderless printing in digikam, I have to do it in the turboprint ui.
Something to check for each print or set of prints. It would be nice if the
settings dialog were displayed by dt prior to actually printing. Another
benefit of this would be the preview the dialog provides, it would for example
show the nagware logo.

This setup apparently does not provide any means for controlling crop, but my
2:3 photos needs to be cropped to actually fille a DIN A4 paper, so to produce
a print filling the paper, I first need to use the crop and rotate module.
Given a margin, this would require math skills applied and a custom crop, so
it would be nice if the print view could provide a cropping tool.

Turbo

So I did this:
Selected a photo for printing
Crop to DINA aspect for printing on A4
Margins set to 0
An additional style selected, append mode.
Enabled borderless in Turboprint control for the printer
Selected "Glossy" paper type in turboprint control.
Selected high quality in the turboprint control.

I printed on a Epson premium semigloss paper.

Result:
Turboprint is faster than the epson driver printing in "Photo Best" quality.
Very nice quality print, good, clear colors and no problems with ink :-)
Style was not applied. (I use style in a similar way in export presets, for
example for adding watermarks, there it works.)
A BIG, UGLY turboprint logo on the print, even their docs says it will appear
AFTER the 30 day free trial period, only if you don't buy a licence. I
installed from aur (archlinux user repository), which may differ from the
trial package one can download from turboprint.info.

Conclusion:
I'd really like to try printing without the nagware logo before buying a
licence, althoug the price isn't a problem.

Good support in dt is missing, as in the printing options are not made
available prior to printing. It is really not better than using the epson cups
driver in this respect. Not sure about the quality yet.

This setup apparently does not provide any means for controlling
crop, but my 
2:3 photos needs to be cropped to actually fille a DIN A4 paper, so
to produce 
a print filling the paper, I first need to use the crop and rotate
module. 
Given a margin, this would require math skills applied and a custom
crop, so 
it would be nice if the print view could provide a cropping tool.
Turbo
So I did this: 
Selected a photo for printing
Crop to DINA aspect for printing on A4
Margins set to 0
An additional style selected, append mode.
Enabled borderless in Turboprint control for the printer
Selected "Glossy" paper type in turboprint control.
Selected high quality in the turboprint control.
I printed on a Epson premium semigloss paper.
Turboprint is faster than the epson driver printing in "Photo Best" 
quality.
Very nice quality print, good, clear colors and no problems with
ink  :-)
Style was not applied. (I use style in a similar way in export
presets, for 
example for adding watermarks, there it works.)
A BIG, UGLY turboprint logo on the print, even their docs says it
will appear 
AFTER the 30 day free trial period, only if you don't buy a licence.
I 
installed from aur (archlinux user repository), which may differ from
the 
trial package one can download from turboprint.info.
I'd really like to try printing without the nagware logo before
buying a 
licence, althoug the price isn't a problem.
Good support in dt is missing, as in the printing options are not
made 
available prior to printing. It is really not better than using the
epson cups 
driver in this respect. Not sure about the quality yet. 
Kindly,
Anders

As already explained here : none less costly

Or just print as-is but don't expect exhibition like quality.

You may also want to create your own profile:
https://encrypted.pcode.nl/blog/2018/06/18/practical-printer-profiling-with-gutenprint/

I had done so, and wrote also so article about this. But at some point the
rendering was broken and I didn't have the energy to recreate for the 3rd
time my profiles. Also not the energy to create a profile for all my
papers. At the end of the day TurboPrint is far less costly and works very
nicely.

Definitely true, but printing by yourself offers more choice of paper and a quicker processing of test prints.

If you can get the settings right, printing for yourself is cheaper, I
believe. Plus it is instant, and more versatile.

Manufacturer provided drivers of good quality is one of the reasons for
getting an Epson printer. :)

Linux drivers from Epson have mediocre quality often with lower
resolution and no advanced features like color management. Works for
office job, but this is not why we buy Epson printers...

http://nc.alweb.dk/index.php/s/WEI1JVN4Af7lfnm

Here is a (mobile) photo of two prints of the same image, the turboprint
result on the right have a grenish tint, compared the the result of the epson
driver. Of cause this may be fixed by fiddeling with the color controls in the
turboprint driver settings, but it does not appear an easy task! Alternative
could be to buy a profile from zedonet. The turboprint print also have better
contrast in the shadows (the trees in the background, the wawes and dark
clothing)

Both prints are printed on epson semigloss paper in best quality (as provided
by each driver).

The epson driver print looks much more like what is on my screen, and both the
exported jpeg (srgb) and the digikam darkroom and print view display of the
photo.

I did a test more, trying to compensate for the green tint on the turboprint
print, with some degree of succes. However, I can't seem to get it to print
borderless from dt. This is a key issue for me, does that work for you out
there?

I know nothing about printing from dt, I just don't use it. Regarding
your green tint problem: it would be nice to see original digital
picture for fair judgement. Comparing display with prints gives little
information if your display is not color calibrated. In my case the
only thing I play with is brightness — I increase it a bit for pictures
with lots of dark shades before printing.

Yes. In the turboprint control, in the layout tab, A4 is selected and
Borderless checkbox checked. This is also displayed as expected in the printer
properties dialog in digikam print creator, as the page size is shown as "A4
Borderless". Judging from the docs, this is how it works in tp, if you want to
create a custom page size, you have to decide if it is for borderless or not.

I wrote zedonet and asked if this is a nagware issue, because actually I'm in
doubt, but no answer so far.

Never tried custom paper sizes, but regular sizes works for me. Just
double checked both border and borderless modes from Gimp Turboprint
plugin (version 2.46).

Anyone knows if this part of dt is being worked on?

A good reason for working on this: Printing from digikam, without having to
export a jpg first, yelds significantly better results here, when exporting
sRGB jpeg. Colors are simply not as good after the jpeg step.

I'm yet to try exporting using adobeRGB and/or prophoto colorspaces, which may
help a bit.

Post by Anders Lund
sRGB, and that is clearly visible in the prints, while on my laptop display

(very poor) the difference is very small. Probably, exporting to high quality
tiff or png is also better than using jpeg.

If you have digikam installed, you can
cp /usr/share/digikam/profiles/prophoto.icm ~/.config/darktable/color/out/
and restart dt to use the ProPhotoRGB colorspace in the color/output color
profile module. (you probably need to create ~/.config/darktable/color/out
first).
The similar paths for windows/mac are unknown to me.

In my own opinion Adobe RGB give much better results regardless bit
depth of file (8 or 16 bit). Exporting to TIFF is not a problem in dt.
Difference between JPG and TIFF (both in Adobe RGB, 8 bit) is
negligible on small formats like A4-A3. But you better make your own
tests with something like this — https://drive.google.com/open?id=1wXnh

Hello,
I just tried the printing functionality in dt.

I tried it some while ago and was both impressed (with the work that had been
done) and frustrated )in that it seemed to suffer from tunnel vision).

Post by Anders Lund
First, I did not get presented with printer settings,

I did, and that was the problem.
I have a B&W laser; a very nice one, but it is B&W.

If I want colour I have to ship the images off to one of the on-line services.
This isn't too bad. I can make custom seasonal greeting cards that way for
around $0.15 each, which is actually better than store bought ones. (perhaps
they have to recover the cost of copyright on the tacky image and the tacky
verse inside whereas I can supply my own tacky image and my own tacky verse.)

The downside is that these services are hung up on traditional sizes that photo
shops have been dealing with for more than a century now, and that doesn't quite
correspond to the size of the images that I generate. But the DT print module
does supply those constraints :-)

I have an inkjet printer in the basement, a discard. I found it was more
trouble than it was worth for the use I made of it. I don't need colour
printing in my day to day work flow, only occasionally, and then in batches, and
that type of printer is not suited to batches. That's why I use the print
services. A fast (aka laser) colour printer is beyond my budget.

So my problem is that while the DT print tool is very nice, it outputs to the
printer and not a JPG or TIFF that I can send off to the print service.
I have to work out the rations by hand and do a regular export.

Or is there an export function in the print module that I missed?
