I think I agree with Solomon here.  I do have some other thoughts/concerns,
1.  Is changing the base unit going to cause problems with cupstestppd ?

2.  We have had the messiness of 'mm' 'points' and 'inches' for quite some time.  We saw how ugly it is when this macos bug emerged.  The  bug first appeared with v3.x.  Robert, I know you *really* don't like making big changes even if it the right thing to do.

2a  What problems might this cause with cups-genppdupdate?  There are going to be users that already have modified their PPD defaults through the CUPS web interface or command line.  Also, at least in macos, users can create Custom Presets either for one printer or for all printers in the standard Print Window.  I think this is going to get very messy and problematic very, very quickly.  I may not be thinking correctly on these point or overanalyzing.

While the current bug in macos only affects those printers that print on CDs/DVDs, it is still a nasty bug. My immediate concern is to get something out for macos users that won't crash applications when they try to look at and set Printer Features.  I think Steve is having problems getting the ARM binaries to work and to make a fat binary. He will have to let us know where he is.  At this point, I would settle for a x86_64 only release.  I is easier to fend off complaints of not not having native code for the M1 chipset than deal with drivers that can crash applications. As I recall the last patch Robert has us try solved the problem.

[Gimp-print-devel] Mac OS X issue

[Robert K. <rl...@al...>]

I apologize that I've dropped the ball on this.

Unfortunately, it looks like whatever solution we come up with is likely to be messy (as is often
the case when the underlying breakage lies elsewhere).  IIRC the problem was with the *Custom
keywords for any option other than paper size.

There are two broader possibilities: make a change only for OS X, or make a change for everyone.
The former has the advantage of not inconveniencing Linux users who rely on the functionality of
custom CD sizes/hubs, but the disadvantage of increasing complexity.  I'd rather not add further to
the testing matrix or have problems that are hard to reproduce based on OS.

As far as solving the OS X specific problem, there are a few ways of going about it:

1) Use the gross/fine adjustment paradigm we currently use for floating point numbers.  The
difficulty is that for options other than page size we're specifying dimensions in mm rather than
points; for CD sizes and the like, points aren't a very natural unit of measurement.  So coarse/fine
adjustment will yield weird things like 101.9 mm + fine adjustments of .035, .072, .107, .143... mm,
which is meaningless to people.  Plus, it adds the complexity of a fine adjustment option.

1a) Do this, but using points as the unit.  The divisions and subdivisions will be easy enough; end
users won't like having to think about points for their CD diameter and hub.  Same fine adjustment
problem, though.

2) Remove the custom point size altogether, treat it as an integer value at least externally.  This
is simple, but it means people who really want very precise positioning (better than about 0.4mm or
1/100") will be out of luck.

3) Make the base unit for the PPD files be 0.1 point rather than 1 point.  This makes the number of
choices very large (CD diameters have a range of about 40 mm, so that would mean 400 choices).  I
suppose we could make the base unit be 0.5 point rather than 1 point; that would at least reduce the
worst case error by a factor of 2, so about 1/200".  That might be good enough.  Thoughts?

I'm sort of leaning toward simply changing the base unit for the PPD files to 0.5 point.  That will
still make for a lot of option choices and we'll need to test to make sure that that doesn't cause
additional problems.  What do people think?

[Gimp-print-devel] Anyone interested in a few projects?

[Walker B. <fo...@wa...>]

Hey all,

In 2016 and 17 (forever ago it seems) my company paid Solomon to make some custom LUT code inside Gutenprint for Epson-printers. We got it working as an in-house implementation for some experimental monochrome printing that we do at Cone Editions Press here in Vermont. 

To that end:

1. I’m wondering if anyone would be interested in a bit more paid (FOSS) work to actually get the LUT code and workflow validated and working in the current Gutenprint master branch. Robert did some initial LUT-work there but I was never able to implement the code properly because I’m just kinda not smart enough. I think it’s a useful addition to be able to do externally linearized LUTs per channel or color . . .

2. I’m wondering if anyone is interested in some paid work to do this LUT work for Canon. If we can do the LUT work inside Gutenprint then maybe someone can develop a proper open source workflow for monochrome ink printing on the Canon platform. 

3. Finally, DITHER. All the dithers in Gutenprint are channel unaware meaning a dot placement on one channel (take Cyan) is not aware of the intersecting lighter channel (Light Cyan) dot placement creating randomized double drop overlaps. This is generally fine for color printing (CMYK) but does create unnecessary dots and has always been a problem for multichannel monochrome printing. A much higher-quality way to print would be to calculate randomized dither points only inside the drop voids of adjacent darker or lighter channels of the same color. This would minimize ink bleed, maximize total ink limit, maximize gamut, and minimize noise, and increase real-world resolution of fine details. What are your thoughts on that code? Is it needed or not really? Was this part of the never-finished “Even Better Dither? Ideally the Ordered New would be channel-aware . . .

Best regards all,
Walker Blackwell

Just so I'm clear what you're referring to here; "print from other 
windows computers" is done over the network to a ASK2500 connected to a 
MacOS system running gutenprint?

And can you include a photograph of what you mean by "not correct" 
colors?  A print of something like this:

Yes, there are some issues with the next version for macos.  We found a very nasty bug that was in v5.3.3.  It only affects a small number of printers -- those that can print on CDs and DVDs.  It is known what causes it, but it is a macos issue only (Gutenprint is used on Linux) is and the fix is being worked on.  I believe there is also an issue with getting the code properly signed and notarized.  I think Apple made some changes in the number of folders you can have in a folder.

Daniel, my guess is that you are getting the error because you do not have Rosetta installed.  Rosetta is the interpreter that allows Intel code to run on the new chipset.  Normally an application that need to run Intel code will automatically ask you to install Rosetta.  Nice and easy.  Gutenprint is not an application however. It is a set of drivers.  You need to install Rosetta from the command line.  A bit geeky or nerdy, but not difficult.

1.  Be sure you are running as an administrator.
2.  Open the Terminal application  /Applications/Utilities/Terminal.
3.  Enter or copy and paste the following command into the Terminal window

sudo softwareupdate --install-rosetta

4.  Enter your password and hit the Return key.  Nothing will show as you enter your password.  You will have to agree to Apple's license agreement and the software will be installed.

Gutenprint should work fine now.  If that doesn't solve your problem, please post back and we can look for something else.

[Gimp-print-devel] Gutenprint driver Big Sur - Fujifilm ask 2500

[Alessandro <ale...@fo...>]

Hi,
I’m having trouble setting up a old printer with the new mac mini m1 and the new os x.
I have an old Fujifilm Ask-2500 connected to a fritz box with usb share. I also tried all the below steps by connecting directly to usb.
I have installed everything correctly and I can print from the mac and other Windows computers. The problem is that when i print with Mac Os through gutenprint, the print is super low quality and the colors are not correct. I installed the correct ICC profile and tried many combination in the priter setting, like raw color, don’t process color, b&w, ecc. But every time I cannot’ have a correct print.
Do you have any suggestion on how to correct the information the mac send to the printer and have corrects light/colors?

Thanks, kind regards.
Alessandro

[Gimp-print-devel] Big files sending to printer problem.

[ragip a. <ra_...@ya...>]

Hello,
I hope you are all doing well and everything is fine.
In the very past time it was very hard for me to use your drivers in printing since I am no coder or was familiar with Linux.But in the late years with the easy installations of Linux I am printing with Guten Print and loving it.It really beats the thousand dolar rip software in precision.I thank you very much for providing this to us.
I own an Epson Stylus Pro 4900 and I recently tried an Epson SC P8000.My problem is in my works I need to print at least 720 ppi resolution.It was working fine on my printer which is A2 size, 42cm wide.But when I tried a 1 meter x 1 meter print on the  much longer Epson SC P8000 I couldn't send the file to the printer.I tried a 40 cm x 40 cm smaller one which worked fine like it worked on my own printer.File details are as follows;
Resolution: 28346 x 28356 pixels720 ppi  1 meter x 1 meterFile size is: 2.24 GBtif format
I am running Ubuntu Studio with default usb image installation.And printig from the ready came Gimp software.
And my questions are;- Is there a problem with my setup?- Or isn't it possible to print such sizes? What are the limits?- And if it is possible can you please show me a direction how I can do it.
Many Thanks in advance,
Have A Beautiful Day,

Re: [Gimp-print-devel] Printing Problems under OS X

[Benjamin R. <ta...@br...>]

I solved the Problem, it was a misconfiguration in the custom paper format.
The Gutenprint preset has a non printable area of top: 3,18mm and bottom: 14,11mm,
in my settings it was mistakenly set to top:5mm and bottom: 15mm.
Now the size is accurate.
Sorry to bother you

[Gimp-print-devel] Printing Problems under OS X

[Benjamin R. <ta...@br...>]

Dear Gutenprint Team,

thank your for this Driver, the oputput is very good. Colors are finer than printing with the standard Epson driver.
I am running a Epson 7900 with Gutenprint 5.3.3 and I have a problem with the size of the output Material.

When I print on a sheet with for example 610x160mm, with a graphic of 160x80mm. Then the Graphics height is distorted about 10mm,
so that the size of the graphic is 160x90mm.

In the driver I turned on in „Shrink page if necessary: Crop (preserve dimensions) and „Borderless: No“.

Any Idea where this is coming from and what I can do to change it?

Best Regards,

Benjamin

Further searching the web I found at

   https://www.canon.co.uk/support/consumer_products/products/fax__multifunctionals/inkjet/maxify_mb_series/maxify_mb5150.html?type=drivers&driverdetailid=tcm:14-1533036&os=linux%20%2864-bit%29&language=en

that Canon offers  a Fedora/Ubuntu  printer driver "cnijfilter2" version
5.40-1 for the Maxify MB5150 for downloading.  But since there is also a
Gentoo package  "net-print/cnijfilter2" version 5.90  I preferred to in-
stall that instead.

Trying to print a test page via Cups  failed as it did before:  the text
"Printer Test Page" was printed in light grey on the first sheet of pap-
er and then the printer started to empty the paper tray.

So I cycled power on the printer,  rebooted my laptop,  and again sent a
test page  from Cups.   This time nothing happened.   The printer didn't
even flinch and the print job is still pending.

Question: is this driver not required in my case,  or what else is going
on here?

Sincerely,
  Rainer

Re: [Gimp-print-devel] No printing: Gentoo + Gutenprint 5.3.3-r2 + Canon Maxify MB5150

[Gernot H. <aik...@gm...>]

Hello Rainer,
It is quite possible that the MB5100 series is not working properly yet.
I seem to recall that the options related to paper tray, and the sizes
of papers that were able to be used with each of the trays, were quite
complex. I have not checked whether anyone else has reported back on
the MB5100, but can you please communicate with me offline for
specifics of debugging use of the options/defaults. Since you use
Gentoo it is likely I can make some changes to the code, and send you
test jobs which you can send raw to the printer from the command line
to see whether the MB5100 behaviour matches expectations.

It is also possible that there could be problems with the usage on
network connections, so ideally we would like to debug using a USB
connection, if that is feasible.

Best regards,
Gernot Hassenpflug

I do not know if this accurate or not.  When Big Sur was first released, the HP drivers did not work.  I don’t know if they have resolved the issues.  Unfortunately, I don’t think many of the new HP models will work with Gutenprint.  Many of them do not use a command set that Gutenprint supports.

That's what I've installed:

   net-print/cups         2.3.3-r2
   net-print/cups-bjnp    2.0.3
   net-print/cups-filters 1.28.7

And yes,  CUPS does see the printer and provides the following informat-
ion about it:

   Description: Canon MB5100 series
   Location:    Local
   Driver:      Canon MAXIFY MB5150 - CUPS+Gutenprint v5.3.3 (color, 2-sided printing)
   Connection:  bjnp://192.168.2.114:8611
   Defaults:    job-sheets=none, none media=iso_a4_210x297mm sides=two-sided-long-edge

Sincerely,
  Rainer

Rainer,

It would be useful to know:

- What driver you are using with the printer?
- What version of CUPS comes with your Gentoo

There have been a number of bug fixes in CUPS' support of Canon AirPrint/Mopria-compatible printers (like this one) over the last year, so it is possible you are just running into a known CUPS bug.
