MrBrutico,

From the output you posted, the problem is this:

*   multilib-strict check failed!

I'm not sure, but you could try the following:

Code: Select all

FEATURES="-multilib-strict" USE="mx920" emerge =cnijfilter-3.90-r2

MrBrutico · Post by **MrBrutico** » Mon Jul 15, 2019 7:11 pm

Thank you! installed but does not print anything

It marks me this error in administardor of printers cupsd "/usr/libexec/cups/filter/pstocanonij"

Fitzcarraldo · Post by **Fitzcarraldo** » Tue Jul 16, 2019 10:15 am

MrBrutico,

Do you mean that the error message is telling you that /usr/libexec/cups/filter/pstocanonij does not exist? What precisely is the error message?

If the error message is indeed telling you that /usr/libexec/cups/filter/pstocanonij does not exist, have you checked if pstocanonij exists in a different directory? If it does, you could try copying it into the directory /usr/libexec/cups/filter/ to see if the driver then works.

EDIT: Looking at the USE flags for that overlay's ebuild cnijfilter-3.90-r2.ebuild listed on https://gpo.zugaina.org/net-print/cnijfilter , another thing to try would be:

Code: Select all

FEATURES="-multilib-strict" USE="canon_printers_mx920 cups -servicetools" emerge =cnijfilter-3.90-r2

What is the current way to print on an Canon Pixma MX925?
There is only net-print/cnijfilter2-5.70 in Portage, and some net-print/cnijfilter-3.80 in the Overlays. IPP and LPD doesn't work.
Canon is providing a cnijfilter-source-3.90-1.tar.gz:
https://www.canon.de/support/consumer_p ... 864-bit%29
On some OpenSuse I'm using the printer succesfully with a version 3.90 and cnij:// device class.

Have you tried gutenprint? They say (website) that the mx9** series is experimental, but they might work.

I have an old mg8200 series and this is what I have installed
net-print/cups-2.2.13
net-print/cups-bjnp-2.0
net-print/cups-filters-1.25.11
net-print/gutenprint-5.3.3

Edit to add: are you printing to this printer locally (usb/?) or network?

Massimo B. · Post by **Massimo B.** » Sun Mar 15, 2020 8:25 am

gutenprint would be an alternative, I tried that years ago. But it was always lower quality and speed compared to the manufacturers drivers. And because those are working well on the other OpenSuse system, I would prefer them. Is there no official ebuild installing the Canon drivers?

I tried to make a copy of the cnijfilter-3.80.ebuild from the calculate overlay, renamed it to 3.90, adapted SRC_URI, disabled the local patches:

Code: Select all

SRC_URI="http://gdlp01.c-wss.com/gds/1/0100005171/01/${PN}-source-${PV}-1.tar.gz"

It loads the tar ball, but fails at building:

I tried all the ipp urls and using the 3.90 .ppd file, 'printer' resolves to the printers IP here:
ipp://printer/ipp/print
lpd://printer/queue
Also http://printer/ipp like mentioned in https://oip.manual.canon/USRMA-0228-zz- ... 0_060.html .
None is working.

I installed the sources from the cnijfilter-source-3.90-1.tar.gz from Canon:

Code: Select all

./autogen.sh --program-suffix=mx920
make
make install

That has installed a new binary /usr/local/bin/cifmx920. What can I do now? The cnijnet:/<mac> is not provided yet in cups, even after restart, eventhough I have additionally installed net-print/cnijfilter-3.80 from the calculate overlay.

Is net-print/cups-bjnp installed?
If i remember it right then it just to:

cnijnetprn --search auto

And use that output to lpadmin like something like this:

Interesting, no I did not have that. is net-print/cups-bjnp always required additionally to cnijfilter? After installing, I get this result

The only combination I got some test page printed now is lpd://printer/queue and Gutenprint PPD. After switching to the Canon PPD, printing fails. Switching back to the Gutenprint PPD, test page printing now also fails with "page margins overlap". I need to delete the printer and re-add it. Anyway I remember Gutenprint was slower and worse quality than the manufacturer drivers.
How can I get those working?

I recently installed the gutenprint to replace the manufacturer's drive and did not notice any difference in print quality and speed. To make it work via the network I installed the avahi.

You are right. I clean gutenprint and print normal with driveless. Than i said above only avahi was necessary. Thank you.

I have a problem with permissions, trying to use scanner and I just can't figure it out, looked at Wiki but that didn't help with permissions.

Code: Select all

$ lsusb
Bus 001 Device 004: ID 04a9:1721 Canon, Inc. PIXMA MP210

$ sane-find-scanner
could not open USB device 0x04a9/0x1721 at 001:004: Access denied (insufficient permissions)

# sane-find-scanner
found USB scanner (vendor=0x04a9 [Canon], product=0x1721 [MP210 series]) at libusb:001:004

Configured sane-backends from the Wiki, scan app is simple-scan.
I'm in the groups scanner and usb
In short, if I run simple-scan as root it works, but if I run it as user it says that scanner is not detected.

Any help ?

EDIT: Found the solution on previous page with udev rules and that worked!

I still often get this failure after updates. Usually I solve it be re-modifying the printer from webinterface and re-selecting the same PPD file eventhough its version is still unchanged.

If anyone with a Canon PIXMA printer used to use Canon's obsolete cnijfilter-3.20 driver but nowadays has to use the Gutenprint driver (net-print/gutenprint), I have updated the net-print/cnijfilter-3.20 ebuild to get it to build in my Gentoo Testing (~amd64) installation with a local overlay. I have created an additional patch and updated Rev. 3 of the ebuild. The ebuild has to be merged in conjunction with the ecnij.eclass file that user Evert produced in 2022. All necessary files (including ecnij.eclass) are in a tarball that can be downloaded from Gentoo Bugzilla Bug Report No. 130645 Comment 266. The files are listed below:

ecnij.eclass goes in directory /var/db/repos/local/eclass/
cnijfilter-3.20-r3.ebuild goes in directory /var/db/repos/local/net-print/cnijfilter/
The patch files to go in directory /var/db/repos/local/net-print/cnijfilter/files/ are:
cnijfilter-3.20-1-libdl.patch
cnijfilter-3.20-4-ppd.patch
cnijfilter-3.20-7-cups-1.6.patch
cnijfilter-3.40-4-libpng15.patch
cnijfilter-3.70-1-libexec-backend.patch
cnijfilter-3.70-1-libexec-cups.patch
cnijfilter-3.70-6-cups-1.6.patch
cnijfilter-3.70-6-headers.patch
cnijfilter-3.80-6-headers.patch

I am able to merge the ebuild in my Gentoo Testing (~amd64) installation and can print successfully to my PIXMA MP560. I have not tried merging the ebuild for the other models of printer this ebuild is supposed to support, so YMMV.

There is a lot of obsolete CUPS API source code in the Canon package cnijfilter-source-3.20-1.tar.gz dating from 2009, hence the number of patches. However, those existing patches do not cover deprecated CUPS API source code in the Canon package. Future versions of CUPS may drop support for that deprecated source code, so I do not know for how long it will be possible for this latest ebuild to be used.

Again failing after some updates. That whole cups and Canon issue is very very annoying. I tried re-creating the printer configuration, using Gutenprint driver, trying the ipp:// and socket:// addresses.
This is what I get from /var/log/cups/error_log:

With lpd:// is prints a test page, and also a text page from Libreoffice.
But when printing from Gimp, I see it spooling

"Spooling job, 85% complete."

but after 100% nothing happens, no action on the printer. And no error in error_log. Even the finished job doesn't have a failure note.

CUPS is moving towards 'driverless printing'.
If your printer supports wifi-direct or airprint, it supports CUPS driverless printing too.
Hence the filters not being installed by default with CUPS and longer.

Ok, the failing Gimp printing might be a Gimp specific issue. If I save the file as JPG and print from Geeqie, it works.
However lpd://printer/queue seems to be the only working URL for this printer.
Then I tried the canonmx920.ppd downloaded from the customer:
https://www.canon.de/support/consumer/p ... pe=drivers
I can't print any testpage with that and don't see any failure on the print job. The only working driver is "Canon PIXMA MX925 - CUPS+Gutenprint v5.3.4" from net-print/gutenprint.
However it is weak when trying to change any contrast/coloring in the driver settings for fotos. Increasing the contrast to 1.5 for instance makes all black disappear, so I need to keep the default settings.
