I suspect the problem here is that the version of Gutenprint you are 
using is outdated -- about two years ago we fixed a long-standing bug in 
the dyesub gamma correction code but I don't believe that this fix has 
shipped in any Raspbian OS version.

These instructions should suffice for rebuilding Gutenprint on a RPi:

  https://www.peachyphotos.com/blog/stories/building-modern-gutenprint/

 (Since you're using an RX1, you can stop after the 'service cups restart' 
  step in those instructions)

Once you have that updated version installed, make sure the 'Legacy 
Dyesub gamma curve" option is set to False (double-check in the CUPS 
user interface) -- Then the color output will be indistinguishable from 
Windows. Note that you will still need to use DNP's provided ICC profile 
with profile-aware image processing/printing flows in order to get the 
best results.

The "Generic PCL 6 LF Printer wide margin" might work for you. It may not have all the features of the Sharp driver. Someone else may know if one of the other Sharp printers Gutenprint lists might work better. Gutenprint only supports the printer function of multifunctional devices.  For the copier part of the printer, you could try Apple's Image Capture application included with the operating system.  There are several third party scanner applications (they cost money).  I like and use VueScan.  Not an endorsement, just a happy customer.

Let us know if the Generic PCL LF Printer driver works for you. If it works, we will probably add the printer to the list of printer Gutenprint supports.

[Matteo S. <de...@ou...>]

Hello,

I am not sure what the proper path is to request the addition of a printer driver to Gutenprint, so I have sent it here.

I have a Sharp AR-M355N printer that does not provide a driver for the newest macOS versions and I was wondering if you would be able to add support for it in Gutenprint.

Thank you for your assistance and let me know if you require any further information.

Was there something in particular that wasn't working?  Perhaps there wasn't a driver for your printer?

There is an Uninstall Gutenprint application on the disk image that has the installer.  You will manually have to remove any printers you created.

[Gimp-print-devel] DS-RX1HS color shift when print via Gutenprint/CUPS vs Windows

[David L. <da...@pa...>]

Hello Support,

I am a relatively new owner of a DNP DS-RX1HS printer. I've been using it
for about six months with all printing via Windows 10. Now, I am trying to
add some automation to my workflow, and I set up a print server on a
raspberry pi using CUPS/Gutenprint. Unfortunately, the color of the 4x6
prints differs between Windows 10 and CUPS via raspberry pi. I'm using
default configurations of each.

At first, it seemed that the prints from CUPS/Gutenprint were faded. The
colors didn't have the same pop as when printed on Windows. However, I
think there is a bit of a red shift distorting the color. Everything I
print via CUPS has the same issue. I don't see a specific CUPS driver on
the DNP support page nor any further documentation on the settings
available to me in the CUPS settings for the printer. I tried a few
different settings (default type = photograph, best color, RGB vs CMYK
mode) without much success. It doesn't seem to matter whether it is an
image from Illustrator, a photobooth collage from Wifibooth, or a snapshot
from an iPhone, all of the prints suffer from a color problem when printed
to the RX1HS over CUPS/AirPrint on raspberry pi connected via USB. The same
files print great when using the regular Windows 10 driver and direct USB
connection. Unfortunately, I need Airprint to work for my photobooth
(currently Wifibooth).

For better or worse, I have a photobooth event soon and it seems I have to
choose between a) no automation with Windows and better color, or b)
automated printing via CUPS/Gutenprint with poor color.

Please send recommendations for further troubleshooting and/or resolution.

Best regards,

David

Hello Konrad,
When you connect directly to the Mac, are you doing so via USB, and
what driver are you using on the Mac where you say it is working fine?
The gutenprint driver?

The screen bit depth should have no effect on Gutenprint; it doesn't use the GPU in any way.

Can you check what driver you're actually using with your printer?  You mention both Gutenprint and
TurboPrint; which one are you actually using, and what printer?

The LaserJet P1102w uses a proprietary printer language that Gutenprint does not support.  In addition, I think this is one of the HP printers that needs to have the firmware sent to it every time the printer is powered up.  The firmware also would be proprietary.

Try one of the similar printers, and see whether selecting the matte black ink set actually does
select matte black vs. photo black.

[Gimp-print-devel] bug Gutenprint ?

[Michael <die...@we...>]

Hallo,
mit gutenprint habe ich große Probleme:
1. Gimp druckt nicht, wenn ich Gutenprint auswähle.
2. Gimp druckt ca. 8% zu klein, wenn ich den normalen Druck, vermtulich
CUPS auswähle. Erst wenn ich Gutenprint deinstallilere, druckt Gimp in
der exakten Größe.
Mein System Manjaro XFCE.
Ist dieser Fehler bekannt?
Schöne Grüße

Michael

------------------------------------

Hello,
I have big problems with gutenprint:
1. gimp does not print when I select gutenprint.
2. gimp prints about 8% too small when I select the normal print,
presumably CUPS. Only when I uninstall Gutenprint, Gimp prints in the
exact size.
My system Manjaro XFCE.
Is this error known?
Greetings

On a lot of printers, matte vs. photo black is selected via the init sequence, not by ink channel ID.

Epson introduced violet with the SureColor line as their “commercial” 99% Pantone match color. It’s for contract proofing, etc.

Because its now a live-channel (not a damper switch channel) I think this may be different.

It may be the 11880 (also live black) selector . . . I’ll test next week unless someone else wants to install and mess with the P800 driver (which does work for PK btw).
