[Gimp-print-devel] gutenprint prints to smal

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

Hello,
I have Manjaro Linux and the latest Gutenprint. When I print with it,
the images just get too small no matter what I do.
I have to set the scaling to 106% before, then the size is right.
Do you know the problem?
What can be done?
If I uninstall Gutenprint and then the prints get exactly the size they
should. Strange.

Schöne Grüße von Michael

Re: [Gimp-print-devel] Gutenprint 5.3.3 support for Monterey

[Andrey K. <An...@Ka...>]

Dear Matt, 

  The installation as per the provided instructions went smoothly. 
  After the installation I Reset Printing system and installed the Guteprint driver for my legacy HP printer. 
 
  Let me test the driver for some time. 
  I will come back with a report on testing results.

Yes, Gutenprint 5.3.3 will install and work on Monterey running on the M1 chip.  The M1 chip necessitates the presence of Rosetta.  If you have not already installed Rosetta, open the Terminal.app (/Applications/Utilities/Terminal.app).  In a Terminal window, copy and paste the following command and hit Enter.  You will be prompted for you administrator's password for your user account.  Be aware that nothing will appear on the screen as you enter you password.  Hit Enter after you enter your password.

It could be that you had been using an older version of Gutenprint or perhaps something else went wrong in the transfer.  You should be able to just install the current version of Gutenprint 5.3.3 to solve the issue.
gutenprint-5.3.3_rev.dmg <https://sourceforge.net/projects/gimp-print/files/gutenprint-5.3/5.3.3/gutenprint-5.3.3_rev.dmg/download>

If your new computer uses Apple's own processor, you will have to have Rosetta installed.  If you have not already been prompted to install Rosetta, you will have to do it manually.  Open the Terminal.app (/Applications/Utilities/Terminal.app).  In a Terminal window, copy and paste the following command and hit Enter.  You will be prompted for you administrator's password for your user account.  Be aware that nothing will appear on the screen as you enter you password.  Hit Enter after you enter your password.

sudo softwareupdate --install-rosetta --agree-to-license 

The uninstaller seldom works after a system upgrade.  The software receipt is frequently not copied over to the new system.

[Gimp-print-devel] Different 'B' of 'RGB' is printed with Canon and Gutenprint driver on Ubuntu 22.04

[Ray X. <sno...@gm...>]

Dear Developer,

I tried to install my MG3080 inkjet printer on Ubuntu. Firstly I had added
the printer with the default driver Gutenprint 5.3.3 before I found the B
of RGB a bit deeper blue. Then I installed the official Canon driver then I
found the color is much better.

So I think there may be some issues with the Gutenprint driver.

The attachments are the files I scanned for reference.

Well, what I said is basically interpretation of what Mike says - in 
case you need further functionality, write/use a printer application 
(basically future term for printer driver :) ) - there is even a legacy 
printer application which accepts filters and PPDs once you upload them 
into it. It seems you've misunderstood the change - PPD support are 
going away from CUPS, but not from OS - they move to printer 
applications (which are already written for existing driver packages in 
Ubuntu), so you still can use old PPD on Linux. The printer application 
translates all the PPD stuff into IPP and CUPS automatically picks it up 
via mDNS on localhost (it is not shared on public IP, only on your 
localhost address). This way PPD support in Linux stays, CUPS doesn't 
have to check every change it does whether it works with PPDs and do the 
option transformation from PPD to IPP and vice versa and can focus on 
implementing newer IPP features meant for enterprises and better user 
experience.

Any new model support should be written as a native printer application 
instead of classic PPD though, since the current printer application are 
meant for retrospective support (models with PPDs for Linux to keep 
working with PPDs). Gutenprint here will be the first one with native 
printer application so far :)

That is a much more agreeable procedure and attitude in this camp. A 
breath of fresh air. Mike wants to do away with ppd's and that is not 
going to be acceptable as long as there are folks who /will/ spend the 
sheckles to get
the features or performance they want/need.

Doing away with ppd's is a bad idea. I didn't put $750 on my card half a 
decade ago to have it treated
like a $40 Kodak special that WalMart or Target might sell to starving

but its now its bash scripts and g-code  for cnc machinery I've made

Thank you very much, Zdenek Dohnal. I have no clue where you hail from,

Take care and stay well.

AirPrint/IPP Everywhere works over wired network as well, no need to 
require wifi.

AFAIK the reason why some features are missing doesn't have to be only 
because AirPrint/IPP Everywhere design. There can be an issue in 
printer's IPP implementation or in CUPS itself. IMO driverless protocols 
tend to supply basic functionality, so you don't have to worry whether 
your device will be supported on a different OS.

And if user is satisfied with features provided by AirPrint/IPP 
Everywhere (which is subjective), I wouldn't push him to a printer 
driver/printer application. In case he needs further features of the 
printer, use printer driver or printer application.

Let me put it this way, since any such access is not seen locally, it 
only uses my bandwidth
as its fed directly to my circuit by way of the radio in my router. The 
clue was my net bill
which for my use runs about 30G a month, and did not hit my limit which 
is close to a TB
a month, but I noticed that it was up to around 80G a month. So I 
finally found the pw and
logged into dd-wrt to find a strange lease so I bounced him. Back in 5 
seconds, he had
some cracking thing on his cell so his traffic to net surf didn't show 
on his cel bill.
I made a new 25 char pw, bounced him, back in 30 secs. So since I wasn't 
actively using it,
I turned off the radio. I have one of those $100/yr cel phones, normally 
turned off. I keep it
charged so it ready to go if I decide to goto to some kin of my wife for 
a day or 2, something
I can yell for help with if my old ford runs into trouble. Suddenly I 
couldn't keep it charged,
something was turning it on by remote without making a sound locally but 
using up the battery.
I quit trying to keep it charged.

He was a mailman but is now in jail for non-delivery. they raided his 
place and found half a
ton or more of undelivered mail, still in uspo carry bins in his garage. 
So peace has returned
to my locale. But during his reign I had to turn of the radios in 
everything here to keep him out.
At one point he was coming in thru the radio in the rpi4b I run my big 
lathe with. Quite a game
of cat and mouse. In the last couple months I've added a couple rock64's 
to the local net, to
run 3d printers with but I've not enabled either ones wifi. Much saner 
life w/o it. So 100% of
my net is wired. No microphones plugged into any these machines either. 
If some 3 letter
agency wants to hear what I think, let em bring the big truck, easier 
target to hit.

Its options for instance, do not include the choice of which paper tray 
to use, nor does it include using the
color trim options in the ppd. When Mike decides to support the printers 
features, I might consider using
it his way. Until then . . .

I have an advantage over most of you, I've known Mike since the middle 
80's. Long before cups.

Do you let a nearby unknown cellphone into your local network? mDNS 
works by default only in the same network.

And in case you don't want to use mDNS, you can still install the 
printer permanently via IPP port and get the options via IPP as AirPrint 
can do (however you lose the automatic installation...), so in that case 
the attacker would have to get into your network and find out printer's 
IP or hostname (because mDNS doesn't advertise anything).

I consider Airprint a huge security hole, just waiting to be abused by a

Get rid of cups-browsed, and brothers own drivers can use every feature 
these printers have,
including excellent color re-production on good paper.

Hi,

the device supports Airprint, so I would go for IPP Everywhere, just 
don't use lpd:// connection if you want Airprint to work (needs IPP port 
on the printer to be enabled).

IPP device uri you can probably use (if it doesn't work, check your 
printer's manual for proper uri):

ipp://<IP/hostname>:631/ipp/print

where <IP/hostname> is printer's IP or its hostname.

Only if Airprint does not work or its set of options do not match your 
needs, I would recommend using classic Brother driver.

Brother has a driver installer that works extremely well if you remove 
cups-browsed
as it won't allow the brother drivers to be used. It works well here on 
my home network,
and my rpi4, and a pair of rock64's, all armhf or arm64's can all use my 
2 printers. The
big one just happens to be the same as yours.

This is a 6 core i5 machine, so I can't say if they have drivers for 
arm's. But my arm stuff
can see, and use either printer. Just as if it was local to that machine.

Hi Robert.K,

The driver i was using didn't have duplex in the ppd (that i could find).

So i was looking at other drivers and wondering how to find the best 
match to the printer.

Does the PPD file not offer duplex as an option?  The XML files look like duplex should be enabled.

Those refer to the page margins if duplexing is enabled, in points.

Unfortunately, the only documentation is in the contents of the files and the code.

Hi,

I found the printer has duplexing but the driver has not.

In gimp-print-source/src/xml/escp2/model/model_134.xml, it has:
   <margins duplex="duplex">9 9 27 27</margins>

Where do i find what these numbers mean ?

Where do i find what is allowed in any of the xml files ?

[Gimp-print-devel] Banding on prints using custom profiles

[Robin S. <ro...@le...>]

Good afternoon,

I am getting banding in areas of gradual luminance gradient when printing with Gutenprint, as described below.

OpenSUSE Tumbleweed KDE, plasma version 5.25.4
Kernel 5.19.1-1-default (64 bit)
Gutenprint version 5.2.15
CUPS version 2.4.2
Epson Surecolor P600 printer

In order to obtain accurate colours with the printer, I have custom ICC profiles created by the suppliers of the photo papers I use. The suppliers' templates (patch files) are printed from Darktable v4.0 in the normal way by turning off all colour management in Gutenprint and Darktable. The resultant ICC profiles are very good for colour accuracy. However, where a print has an area of gradually changing luminance, visible banding occurs. This is most obvious in desaturated regions; it also happens in more saturated areas but is much less marked.

Darktable's soft proofing displays exactly the same banding. I have created two simple monochrome images with linear luminance gradients and taken screenshots of the results in Darktable with soft proofing on and off respectively. The results are attached.

I have so far had 5 custom profiles created from three different suppliers. All of them show the banding to a greater or lesser extent. The same image files printed on Windows computers and the same model of printer, using the Epson driver and custom profiles for that combination do not show any banding. The conclusion must be that the custom profiles created via Darktable and Gutenprint/CUPS are somehow faulty, i.e. the patch files have not been created correctly.

I also occasionally use Qimage Ultimate v2023.100, a Windows program running under WINE. The ICC profiles created via Darktable produce prints (and soft proofs) in Qimage which are virtually indistinguishable from those in Darktable, i.e. the ICC profiles are fully interchangeable between Darktable and Qimage. Furthermore, if I print the colour patches from Qimage instead of from Darktable, the results are exactly the same. This leads me to believe that the problem cannot lie with either Darktable or Qimage, since the colour patches are printed independently and give identical results.

I cannot compare with images printed directly from GIMP as the ICC profiles created with Darktable or with Qimage are not interchangeable with GIMP - the colours are no longer accurate. I do not know why.

Perhaps I should also mention that prior to using Gutenprint I worked with TurboPrint and results from this show no banding at all.

The only common factor is therefore Gutenprint/CUPS, hence I can only conclude that this is very likely to be a Gutenprint bug.

Kind regards,

Robin Simmons

[Gimp-print-devel] Brother MFC-J6720DW

[Superma <Su...@we...>]

Dear all,

I try to make my brother MFC-J6720DW printer running with CUPS on my
NEXTCLOUDPI Rasperry.

I have already tried with the following print drivers:

  * Brother MFC-9600
  * Generic IPP Everywhere Printer
  * Brother MFC-6550MC
  * Brother MFC-8300
  * Brother MFC-9500
  * Brother DCP-1200
  * Brother MFC-9840CDW BR-Script3

Everytime I am getting the same  / following result:

 1. Print Test Page
 2. Testpage is shown on the spool queue:
 3. Printer is starting and showing "Receving Data"
 4. Printer goes back to standby without printing anything
 5. Printjob is removed from the queue:


Im am having:

  *

What else can I do?
Do I need a separate printer driver file?

Thank you very much for your help.

Manuel

I found at the end of the manual that the 2850 has the same nozzle configuration 
as the 2750.

Hi,

We do not have anybody working on HP printers at this point in time, so it's not going to be
supported unless someone steps up to do the work and testing.

There haven't been any security fixes, so it's not essential that you upgrade if your printer is
working properly.  Still, be aware that 5.2.13 is quite old.

[Gimp-print-devel] Epson Ecotank ET-2850

[Russell S. <rj...@ne...>]

Hi,

I wanted to get this printer but can't find anyone that has tried the Ecotank 
ET-2800 series.

The Ecotank ET-2700 series is on the supported-list.

<https://www.epson.com.au/products/ecotank/ET-2850.asp>

<https://www.epson.com.au/products/ecotank/ET-2750.asp>


The gutenprinted supported ET-2750 has:

   EcoTank ET-2750 	C11CG22501
   PRINTING METHOD 	On-demand Inkjet (piezoelectric)
   NOZZLE CONFIGURATION 	180 nozzles Black, 59 nozzles each colour
     (Cyan, Yellow, Magenta)
   MINIMUM INK DROPLET VOLUME 	3 Picolitres
   5760 x 1440 optimised dpi with (with Variable Sized Droplet Technology)




The ET-2850 has:

   RODUCT CODE 	C11CJ63501
   PRINTING TECHNOLOGY 	4-Colour (CMYK), drop-on
     demand MicroPiezo® inkjet technology
   MAXIMUM PRINT RESOLUTION 	5,760 x 1,440 dpi


The resolution is the same, but the epson specs don't state the nozzle 
configuration for the ET-2850.

Both use the same T502 ink.


I suppose it's luck whether it'll work or not ?
