Hi Solomon, thanks.

1) I can keep doing the tests I can on my printer.

2) If you can coach me on how to do this, I can try to help.


My thoughts on items 3-6:

It seems logical to finalize this release of gutenprint before
migrating to another hosting site, updating the website, and tackling
the migration to GIMP 3 and working up the printer application. If
nothing else, a reasonable way to break the whole shebang into
reasonable chunks.

I can certainly help with website updates once a new home (getting off
sourceforge) is chosen; maybe even do some work before then.

Regards,

Erik

> Solomon, how can I and others help?

It's those big ticket items.  

1) Testing on actual printers

 Other than my dyesub fleet I have no idea if anything else still works 
 on real hardware.  Not that there have been a lot (if any?) changes 
 elsewhere...

2) Regression testing vs older versions

 There is the src/testpattern/Checksums directory in the tree; I need to 
 figure out how to generate a new batch and compare it to the previous 
 release's run.  Then go through the ones that differ and make sure they
 were intentionally changed.

3) Update web site and other public documentation

 * Extract current printer lists for the www site and update accordingly
 * Make it clear everywhere that MacOS is no longer supported
   (at least outside of MacPorts or Fink or whatever)
 * (Really, the entire web site should probably be replaced..)

Longer-term things:

4) Port gimp plugin to GEGL and GIMP3

 Earlier tonight I started getting the basic plumbing in place to make a 
 gimp-3 plugin possible. While I don't expect the actual gimp-interacing 
 bits will be terribly complicated (beyond handing >8bpp image data 
 formats) the real uplift is porting the gutenprintui library from gtk2 
 to gtk3.

5) Picking up the Standalone gutenprint printer application

 The GSoC project completed the initial phase, but a lot of work remains 
 -- general integration and cleanup, the inevitable testing, and 
 (particularly important for me) getting the dyesub backend in, which is 
 likely to take some serious restructuring of how it is put together.

 This matters because it's realistically going to be the only usable 
 path forward for gutenprint in the medium term.
 
6) Getting off of sourceforge

 I'm personally partial to sourcehut, if only because they consider 
 mailing lists (and email in general) to be first-class tools.

 The only things on sourceforge that matter are the mailing list 
 archives and the old release archive.  Both are extractable, though 
 sourceforge now "helpfully" strips out email address.  I don't know if 
 that will prevent re-importing elsewhere.

That's off the top of my head...

Other than some minor fixes, nothing's happened.

I could just create a new tarball but there's still a lot of other stuff 
that historically has happened for releasees -- updated www site and 
other documentation, running and updating regression test suites, and 
more.  All of that takes time, especially when you have to figure it out 
first!

Other major stuff looming -- trying to pick up where the GSoC student 
left off with a native gutenprint Printer Application, and porting our 
GIMP plugin to the 3.0 release.

It has been reported that the p600 driver partially works with the p700.  There is a bug in Gutenprint on macos, however, that will prevent you from accessing any of the printer settings in the print window.  If you try the p600 driver and feel there may be enough usefulness, post back and I can provide an amended PPD for the p600 that will get around the bug.

It does appear that Epson does provide macos drivers for macos 10.13.x.

[Gimp-print-devel] 5.3.5 status?

[Greg T. <gd...@le...>]

I am just making sure I am not missing something, and don't mean to
demand that any person do anything.

I believe that where we are is that in July 5.3.5-pre1 was released, and
we had some discussion about a few minor issues.   And that there has
been no pre2, alpha, beta, rc or release.

(I'm happy to update pkgsrc locally to a new pre/whatever and test, or
to update to a release, when/if that occurs.)

The P600 or P800 might be close enough to work.

This email chain went private, but to follow up here, for the -SL 
variant, Mitsubishi used a unique USB PID and also changed the IEEE1284 
identification string.

Gutenprint has been updated to recognize these, but a week later have 
not heard back if this is sufficient to allow this model to print.

Gutenprint works purely with bitmap data. If the source material is not 
an image then something else has to convert it before it's handed to 
gutenprint.

That "something else" can be the application itself, the framework it's 
using to print stuff, or a filter in the CUPS processing chain (eg 
"pdftoraster").  Since you're seeing wonky fonts, it could be any of 
those layers -- the application (or framework) could be inserting bad 
font data, or the rasterizer could be mis-interpreting said font data.

But either way, by the time Gutenprint is handed the print data, it's 
already been converted to a bitmap.

[Gimp-print-devel] Some fonts produce complete garbage on the printer (OKi MC362DN)

[Shanti-Dominique <mi...@mi...>]

Hello,

I have an OKi printer that worked fine until a few months back. On some 
fonts, it started producing garbage, I suspect that is because the font 
format evolved and the printer does not recognize it. When upgrading myu 
computer to a newer version of Linux, the fonts included have newer 
freetype features that are not supported.

For example, Libre Baskerville is complete garbage. Some other fonts are 
ok, some have minor issues on some letters.

I know that Chromium has an option to print a PDF as an image, and it 
solves the problem, but I cannot print everything from Chromium.

Is there an option to sanitize fonts before they are sent to the 
printer, or to force printing as image?

Thank you.

Mildred

Mitsubishi typically produced special variants of each model, typically 
tied to some vendor's specific kiosk solution (a German company called 
"Silverlab solutions" in this case) *and* additionally being locked to 
vendor-specific media.

Depends on what you mean by "does not work" -- ie what is the specific 
error?

Historically Mitsubishi has changed the USB IDs and tweaked the "start 
print" command slightly vs their standard commercial model.  I don't 
know what they might have done for the CPD90DW-SL.

When you say "did not work" what precisely is the issue or error?

Gutenprint's UP-DR80MD support was written in late 2019 via 
reverse-engineering, ie without any support from Sony.

It is certianly possible that Sony changed something during the 
production run, but one of the points of the "MD" model designation is 
that it's a certified device that doesn't change during its extended 
product lifecycle.

A few other things to check with both the old and new models:

 * What is the 'lsusb' output ?
 * What is the output of 'sudo /usr/lib/cups/backend/gutenprint53+usb' ?
 * What is the output of 'sudo /usr/lib/cups/backend/usb' ?

I wanted to apply the patches as-is, but they mostly fail to apply:

So... I don't know what you used as the "before", but the files you're 
modifying haven't changed since 2019 and 2017, respectively.  Maybe you 
had non-local commits?

Instead of trying to diff two separate git trees, you could make sure 
you have your local WIP repo up-to-date, and generate a patch with 
something like:

  git diff origin/master

Or, if you have these things committed locally, you could do something like

  git format-patch origin/master

And that will generate one patch file for each commit missing upstream.

(Make sure you do a 'git pull --rebase' first though)

The libusb files are used for dye-sub printers only.  You don't need any of the files and may delete them.  Hopefully there will be some documentation for this if there is another Mac release.

The printer should appear in the list of available printers when you go to add it through Printers & Scanners.  You actually don't need to have drivers installed for it to be recognized and listed.  You could use System Profiler or System Information app (/Applications/Utilities/System Profiler.app)  to double check the presence of the printer.  Launch the app and highlight USB in the left side.  If the printer is recognized by the computer, it should appear somewhere  on the right hand side.  If it isn't there, then there is a communication problem between the printer and the computer that will have to be resolved.  Be sure you are using the USB port on the back of the printer.  The USB port on the front is for a USB memory stick.  Also make sure the USB cable is not properly inserted.

[Gimp-print-devel] Trouble setting up printer using your driver Gutenprint 5.3.3

[me2u <me...@ho...>]

I’ve just installed your Gutenprint 5.3.3 on my computer, running macOS
10.13.6, High Sierra. When I opened it, I saw the 6 files in it, including
the installer, but also another one named
libusb—1.0.22.high_sierra.bottle.tar.gz.

I proceeded to install gutenprint-5.3.3.pkg.

I then opened (decompressed) libusb—1.0.22.high_sierra.bottle.tar.gz, since
I running High Sierra. It just puts out a lot of files. What is that for,
what am I to do with those files? Or, is that just something the installer
will use when it sees it is installing to High Sierra?

I restarted the computer, just to be sure.

I then went to try to set up my Canon Pixma MX922, which your Website said
is supported by Gutenprint 5.3.3. The printer is turned on, I am connected
with a USB cable (which works fine on my Epson, so it is a good cable). But
when I click in the System Preference pane Printers & Scanners, the Canon
is not listed under the Printers list on the left. OK, maybe when I seek to
add it.

I clicked on the + sign, the window to add it opened, but it is blank. (It

I *think* Robert used the prefix STP because the first drivers he worked on were for the EPSON Stylus Photo printer (STP), but I'm not 100% sure.
