Trying to install 32-bit Canon printer driver in Xubuntu 20.04, but fails

[ardouronerous]

My printer is a Canon PIXMA iP2770. The official driver is 32-bit only and while there is a driver in CUPS called Canon iP2700 series - CUPS+Gutenprint v5.3.3, it's lacking in features such as draft mode.

I created this tutorial for myself for installing the printer driver in 18.04, however, this tutorial no longer works in 20.04. These are my failed attempts to install the dependencies:

Enable 32-bit support:

sudo dpkg --add-architecture i386
sudo apt-get update

Attempted to install libtiff4:

sudo gdebi libtiff4_3.9.7-2ubuntu1_i386.deb
Reading package lists... Done
Building dependency tree        
Reading state information... Done
Reading state information... Done
This package is uninstallable
Dependency is not satisfiable: multiarch-support

According to the error message, libtiff4 needs multiarch-support, so I downloaded two versions, the 64-bit and 32-bit versions:

multiarch-support_2.27-3ubuntu1.2_amd64.deb
multiarch-support_2.27-3ubuntu1.2_i386.deb

Tried to install multiarch-support (64-bit):

sudo gdebi multiarch-support_2.27-3ubuntu1.2_amd64.deb
Reading package lists... Done

Trying to install libtiff4 again wielded the same results: Dependency is not satisfiable: multiarch-support

Tried to install libtiff4 again, but same result: Dependency is not satisfiable: multiarch-support

I also tried to install libpng12:

I think the multi-arch thing is for installing packages and distributing them https://wiki.debian.org/Multiarch/Implementation

But what if you already have the i386 libs in your binary's LD_LIBRARY_PATH? Since you don't need to compile (cross compiling is tricky) can we do something like you did for audacity in your other thread to bypass the whole installation process and get it to work?

I suppose for driver instead of using a script to start like audacity you should export PATH and LD_LIBRARY_PATH to your .bashrc or .profile like so

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/your/driver's/lib/dir

export PATH=$PATH:/path/to/your/driver's/bin

[ardouronerous]

You mean, download all the i386 dependencies needed to run the printer driver and package them like I did with Audacity? I can try that.

Last year, I gave up on trying to install the printer driver and went to VM instead, so I removed 32-bit from my machine, but I'm running into a bit of a problem trying to re-enable 32-bit support though:

sudo dpkg --add-architecture i386
sudo apt-get update

I don't see i386 in sudo apt-get update's output, did Ubuntu remove all 32-bit repos?

Yes. Except that you want the driver to be activated automatically when the device is plugged in so you don't want to start it with a script like audacity, so you have to export the environmental variables in your .profile or .bashrc.

I don't think it shows the i386 packages separately, also some i386 libs might have been removed from the repo even though the 86x64 version is still available. You can check easily if you have installed synaptic, just open it and check architecture in the left hand panel and it will show you all i386 packages.

OP, try these:

Okay, I saw i386 packages in Synaptic, so the 32-bit repo is downloaded into my system.

How do I download all the dependencies I need for my printer driver though. I managed to do this with Audacity with this command:

sudo apt-get install --download-only audacity

Then I copied all the dependencies from /var/cache/apt/archives directory. How can I do this with deb files?

[monkeybrain20122]

OK I downloaded it, the deb.tar.gz file contains two .deb files. If you extract them there are two sub-directories data and control, the control files tell you what the dependencies are, e.g

Package: cnijfilter-common
Version: 3.30-1
Section: graphics
Priority: optional
Architecture: i386
Depends: libc6 (>= 2.3.4-1), libcupsys2 (>= 1.2.1) | libcups2, libpopt0 (>= 1.7)
Installed-Size: 304
Maintainer: Canon Inc. <sup-debian@list.canon.co.jp>
Description: IJ Printer Driver for Linux.
 This IJ Printer Driver provides printing functions for Canon Inkjet
 printers operating under the CUPS (Common UNIX Printing System) environment.

There is another one for the other .deb

Now the structures of these files look complicated, even after assembling the libs you may not be able to get it to work. Not sure if you can symlink them if you are able assemble all the pieces. This looks a lot more complex than audacity. Not sure whether you need anything in "resources".

[ardouronerous]

Do you have a link to where I can download the deb for the driver?

Sorry, please see my edit.

[monkeybrain20122]

If you look through install.sh, you may be able to figure out which piece goes where if you have resemble all the libs and make the symlinks to the system accordingly. This is going to be tedious.
