It looks to me like it is the right one.  I found this in packet #634.  This is a response from the
printer.  1.3.0 looks like the right device; I'm just not sure how to extract the data from the host
to the printer.

This capture doesn't seem to have any printer data -- just a USB HID 
device and a USB-attached bluetooth device.

I think the capture was attached to the wrong logical bus..

Can you capture the first 16KB or so of the output and send that?  It will be easier for me to try
to interpret (I have tools to inspect the byte stream).  Thanks!

Re: [Gimp-print-devel] Init sequence to disable PW sensor on EPSON

In attacment html file  captured command "load paper" from epson service
utility.
with this command printer load film without any troubles and not checking
with pw sensor
can you tell me what sequences i need to test? Im not sure i can find right
part of sequence by myself

If someone can discover this by decoding the print data (it would probably be in the remote mode
block), I'd be happy to add it.

I know this tricks, but much more easy to rewrite sequence in printer xml
if somebody know what sequence can disable PW

Re: [Gimp-print-devel] Init sequence to disable PW sensor on EPSON

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

There’s a few ways to fix this.

One way could simply be to put OHP Ultra Premium film in there because it’s slightly milky white.

The other thing could simply be that the film needs a white paper behind it when the printer loads the film part (not both film and paper just the paper behind the film so the printer know’s there’s something to load). The XP-15000 printer needs that for film.

You can also put white tape on left and right of film.

Best regards

[Gimp-print-devel] Init sequence to disable PW sensor on EPSON

[Andrew X <68...@gm...>]

Im working with epson L805 and half opaque film and have some troubles when
PW sensor in standard mode (not borderless) trying to check film. With
usual white paper everything works good. I know in other RIP software for
epsons present option to disable PW check. May be i can add some command to
init sequence to disable PW check?

Upstream libusb merged the patch that I added to Fedora, working around
the issue. This means that you have some time to roll out fixes before
libusb actually starts to enforce the new API.

https://github.com/libusb/libusb/issues/1089#issuecomment-1073364149
https://github.com/libusb/libusb/commit/6b29aeb9ca22ed5ea9768020895698bd452c2a85

This will be included in libusb 1.0.26.

Please go ahead. While I had to tweak the patch to apply to git master, 
it's functionally sane and there are no regressions with anything that's

If you didn't, would it be okay for you if I applied the attached patch

[Gimp-print-devel] Cloning command from the Gutenprint web page doesn't work

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

Hi all,

I've tried cloning the repository by the command from the 
http://gimp-print.sourceforge.net/p_Download.php webpage:

git clone git://git.code.sf.net/p/gimp-print/source gimp-print-source

and it ended with following error:

Cloning into 'gimp-print-source'...
remote: Enumerating objects: 57486, done.
remote: Counting objects: 100% (57486/57486), done.

when I used 'git clone https://git.code.sf.net/p/gimp-print/source 
gimp-print-source' from the page 
https://sourceforge.net/p/gimp-print/source/ci/master/tree/, it worked fine.

Is the cloning of git:// target broken or is it just an error on my side?


Thank you in advance and have a nice Friday!

I don't have time for full mentoring (this summer's likely to be quite busy for me), but I can help
provide guidance.  This really is an important project, and I want to see it done correctly (i. e.
not crippled, although I recognize that it may have to be done in stages).

[Gimp-print-devel] Native Gutenprint Printer Application in GSoC - Who wants to mentor?

[Till K. <til...@gm...>]

Hi,

as there is no progress with a native Gutenprint Printer Application I 
have opened this task as a GSoC project idea:

https://wiki.linuxfoundation.org/gsoc/google-summer-code-2022-openprinting-projects#make_a_native_printer_application_from_gutenprint

I want to ask you, whether one of you would like to mentor the GSoC 
contributor on this project.

If so, please tell. I will then invite you as a mentor so that you can 
register.

Sambhav, if you did not participate 2 times in former GSoCs you could 
also participate as contributor and write the native  Printer 
Application. As you probably had already done some initial preparation 
work, you will have already some experience and it will be more easy to 
start with this project. In this case do not ask me for a mentor 
invitation and do not register as mentor as then ypu are no eligible as 
GSoC contributor any more.

Sambhav, if you prefer to mentor someone else on this project, please 
tell and I invite you as mentor.

Hi,

I'm seeing conflicting reports about whether this printer will work with Gutenprint.  It's possible
that the Generic Color Laser or Generic PCL6/PCL XL driver will work with this printer; if you can
try it and it does, please let us know so that we can add it to the supported printer list.

Unfortunately, the HPLaserJet CP1025 uses a printer language that Gutenprint does not support.  There will be no driver forthcoming.
