[Gimp-print-devel] Advice on how to add the Epson SL-D700

[Solomon P. <pi...@sh...>]

I'm trying to make sense of the ESC/P2 driver xml files to add support 
for the commercially-focused SL-D700 printer.  It's roll-fed, 
1440x720dpi, 180-mozzle variable-dropsize printhead), and uses a 6-ink 
set ("Ultrachrome D6-S" CcMmYK).  According to the IEEE1284 data, it 
supports the ESCPL2, BDC, D4, and D4PX command sets.

If I understand things correctly, I will need to create a new 
model(+baseline?) xml file, which in turn will reference media, 
inputslots, qualitypresets, inkgroup, and mediasiszes xml files, along 
with a metric boatload of miscellaneous parameters.

I will be able to derive a lot of what will go into these secondary XML 
files, though a lot of additional tuning will probably be necessary, but 
when it comes to the stuff that goes into the baseline/model files, I'm 
wondering if there is a good candidate to use as a quasi-sane starting 
point.

I know I'm going to make a lot of mistakes, so any advice on how to 
minimize footgunning myself will be appreciated.

Thanks,

 - Solomon

Hi,

I'm afraid I don't understand your question.  Gutenprint is not by itself a RIP; it's simply the
drivers required for the printer to print.

Hi,

In response to your questions:

1) We don't have any Android support in Gutenprint.  It might be possible to port; I don't know
whether anyone has done it and I personally have no Android experience.

2) The same applies to the NDK.  In addition, be aware that if you want to redistribute the result,
you may only do so under the terms of the GPL(v2 or later).  If you intend to use this only
personally without redistribution there are no restrictions.  You will need to make that
determination; I can't give you any legal advice beyond what I said, as I'm not a lawyer.

[Gimp-print-devel] [5.3.4] Fixes for XML files

[Zdenek D. <zd...@re...>]

Hi,

we ran XML linter as a part of rpminspect project[1] on any package 
containing XML files during CentOS Stream development and found out the 
linter reports errors (attached file 'errors') for several XML files in 
Gutenprint 5.3.4.

The attached patch applies cleanly on current GIT master of gutenprint 
and linter in rpminspect doesn't report errors for XML files anymore.

Would you mind applying the patch to the project?

Thank you in advance!

Addendum.  I tried Image Capture with my Epson three in one on Intel chipset.   I don't think that Image Capture is designed to work with  a scanner to print directly or automatically.  It makes a scan and places the file on your hard disk for printing from a different application.  I also ran into problems with Image Capture telling me that there was no document loaded.  I had to set whether the document was on the flatbed or in the document feeder.  I hope this helps.,

Also, you might want to check /Library/Image Capture/TWAIN Data Sources to see if the is an entry for Canon.

Gutenprint does have plans to release a version that is native to the M1 chip.  The current Mac release does work however with the M1 chip as long as Rosetta is installed.  Sorry to say that Gutenprint does not support scanners.

It's not as easy as it sounds.  In 4.x (when it was called Gimp-Print), it dithered multiple shades
together by creating "virtual" shades, the product of the drop size and the relative darkness of the
ink.  For some things it worked quite well, but it had some problems that I don't remember off the
top of my head.

With the standard Ordered dither it's very hard to do this, since it's using a fixed mask.  That's
not the best way, but it's very fast and with small-drop, multi-shade inks, it's almost as smooth as
the best error diffusions that we've tried with none of the quirks of the latter.

Raph Levien came up with Even Tone Screening (which I implemented) and later came up with Even
Better Screening (which I didn't; it was rather thorny).  I don't remember whether there's any
handling of multi-shade inks in that.

Dear devs,

I’m looking Gutenprint code and trying to determine if each channel is dithered independently of every other channel or if they take into account darker shades as no-go placement-points for lighter shades (or vis versa). 

Eg: For Vivid Magenta dots, no Light Magenta dots should be printed at the same coordinates. Is this what “masking” is in the code? If each channel is independently dithered I’d be interested in funding per-color channel-aware dithering . . .

Hello Jim,
Thank you for the report.
I can only speak for the gutenprint driver, although I find it hard to
believe that the Canon driver does not work, since that would be the
official driver provided by the manufacturer. That leads me to think there
might be something else going on.
I believe that the iP90 should work bascially, given the length of time it
has been supported, but there could well be bugs.

Can you set the logging to debug in CUPS, including suiteable maximum log
site (unlimited would be good maybe), and then print using a monochrome
resolution setting (not automatic) and grayscale, on plain media. That
would be the simplest test. You can send me the logfile as a zipped

This printer uses printer code that Samsung developed for many of their printers.  It is not a common set of commands.  Gutenprint does not have anyone to develop a compatible code, therefore, Gutenprint will not be providing drivers for this.  I did notice that Samsung provided Mac drivers through Mac OS X 10.7 only.

Hello,

 

I am a photographer based in the UK and I tried using your printer driver with my Epson P9000 (which your website says is supported but with the label “EXPERIMENTAL”) but the printer would return an error (Ink sets do not match). I think it must be because the P9000 has 10 inks and your driver has a maximum of 8. I tried using the Greyscale setting but that didn’t work either.

 

Do you know if there is a way of making it work?

 

I’ve heard so many good things about your driver that I am keen to try it.

You can subscribe to the gimp-print-devel mailing list via
https://lists.sourceforge.net/lists/listinfo/gimp-print-devel

Gutenprint is licensed under the GPL.  This imposes no restrictions of any kind on use; the license
restrictions only come into play if you want to redistribute it to others.

As for whether your printer is supported, you'd have to specify what it is.  Also be aware that we
only support Linux and Macintosh (currently through roughly 10.14); we're having some issues with
Mac support.  We don't support Windows, although anyone who wants to port it is welcome.

Hi,
Thank you for your interest.
Feel free to ask.
gutenprint also has a license, so you would have to refer to that to see
whether it meeds your needs if the Canon driver license does not.
Most users are concerned about whether they can print from particular
systems, or at specific qualities, or accessing particular options.
So whether gutenprint can do what you want better than the official Canon
driver is dependent on the particular requirement.
