[Gimp-print-devel] Left margin must not be less than 9.000000

[Ken M. <zar...@nt...>]

Hi,

I hope this is the right list to ask for help.  I've got an Epson
Photo R360 using 5.3.3 with cups-2.3.3 and gimp-2.10.20.  Ordinary
printing of text and photos appears to be ok, but -

I'm hoping to print some (tiny) signs for a model, white text on
blue background.  At this point I'm guessing about sizes, so I've
set up a page of A4 dimensions in gimp (actually 209.97 x 297.01
millimetres), put a big blue panel across the top part of the page,
and inserted various white text.

But when I use 'print with gutenprint' and tell it to use the image
size, I get: two messages:

 Left margin must not be less than 9.000000

and

 Print options not verified, cannot print.

In gimp, the ruler along the top is labelled to almost 2500
(pixels?) and the blue runs from about 50 to 2575, starting perhaps
25 below the top of the page.

The printer option for 'Shrink Page if Necessary to Fit Borders' was
set to 'Expand (use maximum page area)' and with that a photo
printed with a tiny white frame at the sides.

Changing to 'Shrink' makes no difference, it still reports the same
errors.

Any suggestions on what I'm doing wrong, please, or alternatively is
it a gimp issue ?

Reference the root level of the hard disk:

I always mention the root level for this as each user has their own Library directory.

I don't know offhand where the .xml files are installed on OS X -- can one of the OS X developers
help with that?

There's considerably more detail on how to use them at
http://www.unny.ca/en/article/327/how-to-print-great-b-w-photos-introduction and
http://www.unny.ca/en/article/361/how-to-print-great-b-w-photos-2-redirecting-the-cmy-channels

It will be easiest if you specify exactly what printer you're trying to do this with; it will make
it more concrete.

[Gimp-print-devel] Simulate network printers w/ various protocols

[Ugurcan A. <ugu...@st...>]

Dear devs,

a while ago (2017) I wrote my bachelors thesis about MITM attacks on
network printers.
Thankfully Robert Krawitz helped me out a lot with decoding ESC/P2 print
jobs.

Now I thought to ask you again for an advise:

In cooperation with other universities across Germany we currently work
on a project which has the aim to raise awareness amongst SMBs by
demonstrating attacks and their mitigations in different scenarios.
My current task is to simulate network printers with different protocols
(PS, ESC/P2, PCL) to avoid setting up physical printers. These printers
should be used to print virtually and capture the network traffic. The
captured traffic is then analyzed automatically to extract print jobs
and show the risks of unencrypted printer communication.

I wanted to ask if there is any way to simplify this process with the
help gimp print. Maybe something you also use for testing.
My current approach would be a CUPS server but this would limit me
probably in terms of protocol diversity(?)

Let me know if you need more information.


Best regards and thanks in advance

Hi Matt,
Thanks for the report. Do you know what the original version of gutenprint
was? As far as I am aware, the code for that printer has not been touched
for some years.
First step would be a CUPS debug log to try and find out what
gutenprint/CUPS says they are doing when printing.
Can you please set debug, print a test job, and send me the debug log? You
will likely have to set the max length of the log file to several millions
bytes, else not much will be visible in the truncated log.
Best regards,

(I should say in advance that I am speaking here in a purely personal 
 capacity, and not for any of the other Gutenprint developers..)

I'm the one who wrote that code for inkjetmall; regrettably I was not 
able to finish what I started and get that functionality properly 
integrated into Gutenprint.

What printer were you intending to use this with?  This is a rather 
critical question, because AFAIK that 44" limitation almost certianly 
isn't a limitation of the IJM codebase, but rather with the printer 
families that Gutenprint itself supports.

I'm not sure if we will be able to support custom work on MacOS -- None 
of the active Gutenprint developers have access to, or experience with, 
MacOS systems, and with every release Apple this task more difficult.

Indeed, I don't think we can even generate a MacOS build that functions 
on the current MacOS release!

Also, it is my understanding that Apple intends to completely strip out 
support for "classic CUPS drivers" in the next MacOS release, so any 
efforts we put into supporting MacOS now would likely be wasted.

We have some work being done to support printing under the new "IPP 
Printer Application" paradigm but it is still in very early stages.

One possible solution to this would be to take a small linux system 
(such as the popular Raspberry Pi), plug the printer into that, and 
print from MacOS over the network.

Which leads to another critical question -- what application(s) are you 
printing from, and do they work via the standard Apple printing APIs?

> Are you interested into this and how much would you charge for such a
> project?

The fancy LUT mapping proof-of-concept work I did for Injketmall worked 
pretty well, but it was mostly tied to Epson printers that spoke a 
specific variation of their command language, and I ran into some major 
challenges trying to make it more generally applicable to other printer 
families.  

Consequently, depending on what printer model/family you intend to use, 
that LUT work might be easy to port over, or it might be much more 
difficult, or it might not even be possible at all.

(Also, If the printer family you wish to use isn't currently supported 
by Gutenprint, that would have to be tackled first)

In a general sense, yes, we like to expand Gutenprint's capabilities.  
However it's not entirely clear what the technical scope of your request 
would entail, even before considering the challenges we face when 
working with MacOS.

While I'm generally willing (time permitting) to do custom Gutenprint 
hacking on a consulting basis, this may be beyond the scope of what I 
can accomplish in a reasonable amount of time.

So let's try and figure out the technical scope of what you need first, 
because that exercise will benefit all of us.

Cheers,

 - Solomon

I've not seen any references to a 'D100'; did you perhaps mean the DX100 
or the DE100?

(BTW, this response isn't only directed at you; yours is the fourth 
 inquiry about these printers I've received this year, and hopefully 
 this way I won't have to repeat myself in another month or so)

Nearly all Gutenprint development is done on a volunteer basis, and 
adding support for the DX100 or DE100 would likely be a substantial 
undertaking.

We do not have access to any programming/protocol documentation for 
these printers, so we would have to resort to reverse engineering to 
figure out what makes them tick.  This isn't inherently difficult but it 
is likely to be quite time-consuming, especially if the output needs to 
be tuned to match Fujifilm's.

Additionally, these are particularly expensive printers -- The DX100 
costs about $2300 with a set of ink/paper -- so we're not going to buy 
one just to tinker with.

So.

If you'd like to see the DX100/DE100 printers supported, you're going to 
have to help us out in some form. At minimum, we will need direct access 
to a loaner printer (and a supply of ink/paper) for a while, and to be 
blunt, work that pays the bills takes priority over volunteer work.

[Gimp-print-devel] Driver development based on Gutenprint

[Aaron C. <aa...@ha...>]

Dear Sir,

My name is Aaron Chan and I am a fine art printer.

For my business, I use a very special ink set call Piezography Ink which 
is a set of ink with different shades of black.
I know the inventor of this ink, inkjetmall, has developed a beta 
version of print driver for think special ink set.
Since his version can only support up to 44" printer, I'm wondering if 
your team would be able to do something similar.
If you could, how much would it cost for such a project.

Basically, what we need is a print drive that can runs on MacOS, capable 
to let us modify the 1-D LUT for linear output with the combination of 
ink and paper.
Are you interested into this and how much would you charge for such a 
project?

Best Regard,

Aaron Chan

[Gimp-print-devel] Printer not working.

[<mad...@li...>]

Good morning,

I've got a Canon BJC-4000 that worked very fine until last July.

Now, after some packages updates it stopped working.

My OS is Debian testing (bullseye), gutenprint is 5.3.3 version (my printer is on the list of supported printers), but when I try to print any kind of document (pdf, txt, odt) the printer start working but the page is blank.

Any suggestions in order to fix this issue?

Many thanks in advance.

Hello Helen,
Very glad to hear gutenprint can help you with your old S9000 printer.

Utilities are not part of gutenprint. There are external open-source
programs (ink, mtink, etc.) for ink level monitoring, but apart from HP
(hp-lip) I do not think there are any vendor-supported cleaning or
maintenance utilities.
Turboprint I understand provides such as service with its printer drivers,
so that might be one good option for you:
https://www.zedonet.com/en_p_turboprint.phtml
According to the S9000 instructions, cleaning can be done either from the
driver, or from the printer itself:
-----
Cleaning the Print Head from the Printer
1
Ensure the printer is on.
2
Hold down the RESUME/CANCEL button until the POWER lamp flashes
once.
Now the POWER lamp starts flashing and print head cleaning begins. Do not
perform any
other operations until the head cleaning finishes.
After print head cleaning finishes, print the nozzle check pattern to verify
that the print head
is clean. If not, repeat print head cleaning. If the head is still not
clean after the third
cleaning, perform print head deep cleaning
----
Note that deep cleaning can only be done from the driver, not from the
printer itself.

Otherwise, manual cleaning would be a good choice if you are able to remove
the print heads.

Hope this helps.

[Gimp-print-devel] Printer driver help.

[Helen T. <ht...@gm...>]

Hi Gutenprint!

I am running OS High Sierra and trying to use a Canon S9000 bubble jet
printer.

At first I downloaded the Canon drivers for snow leopard, and for the most
part, the printer was actually working, but every time I tried to clean the
print heads, I got the 311 error message.

I then deleted all of the Canon drivers and downloaded your 5.3.3 version
with CUPS and all seems to be working once again, except that I now do not
even have ANY printer utility options, so I still can't clean the print
heads - this printer has been sitting in a closet for 10 years, and they
really need cleaning!!  Other than that, I can still print.

Any advice?

Many thanks,

Helen

Can the user specify a page dimension smaller than the actual paper?  If so, this will probably be
needed.

Yes. I've made the get_row function. To clear this out, there's no need for
dimensions variables like left, right, etc. in the cups_image_t structure
now, right? Since it will all be handled by PAPPL and we just have to pass
the data to gutenprint.

Do we have to call stp_print for gutenprint to start printing the job?

And I was asking for the callback function which PAPPL calls to fill the

Hi Fabrizio,
Not sure whether gutenprint can support this printer.
>From the specs
https://www.oki.com/me/printing/products/dotmatrix/24pin/ml5100fbeco/specifications/
I see there following emulation is supported:
ESC/P emulation, IBM ProPrinter emulation, IBM AGM emulation
On Open Printing you can find the following generic ESC/P drivers that
might be what you need:
https://www.openprinting.org/printer/Generic/Generic-ESC_P_Dot_Matrix_Printer
I did not check for IBM emulations.

Hello Moshe,
Good morning, thank you for the notice. Yes, there is unfortunately quite a
backlog of printers that need support added.
I haven't had as much time as I would like to work on adding this, but it
is in the pipeline.
Sorry I cannot give more specifics at the moment.
Best regards,
Gernot Hassenpflug

[Gimp-print-devel] support for Canon TS205 on Raspberry pi

[Moshe R. <mr...@gm...>]

hi,

Gutenprint doesn't seem to support the Canon TS20x series.
Any plans to develop a driver?
I can't print using CUPS from my Raspberry pi.

Thanks!

We really should move this discussion to gim...@li... (gimp-print was the
original name for the project, which started with Mike's print plugin for GIMP and was later renamed
to Gutenprint with the 5.0 release).

For filling the driver data:

Reference the stp_image_t structure defined in include/gutenprint/image.h.  You need to write the
appropriate functions here.  You can see the CUPS driver implementation in
src/cups/rastertogutenprint.c.

Most of these are likely to be pretty simple.  The hard one, of course, is Image_get_row().  This is
called by the core via stp_image_get_row().  This one's going to pull a row of raster data off the
queue and stick it in the provided data buffer, up to the number of bytes specified (so you don't
overflow the buffer) and returns a status (either OK or abort -- that's how a print can be aborted).

The raster format is either 8 or 16 byte (native ordering) K, W (inverse grayscale) RGB, CMY,CMYK,
or KCMY.  There's also a "raw" format, which allows specifying arbitrary channels (currently
supported only for Epson printers, don't worry about that for now).

As for filling in settings, your application does that and does the necessary stp_set_* functions to
set up all the options.

[Gimp-print-devel] Driver for OKI ML5100FBeco Mac OS X

Hi,
any chance to have a driver for that printer ?
Or have a suggestion for a compatible driver that could works with that printer ?
Thanks best regards
