Printing & PDF export' plugin for « Gourmet Recipe Manager » 0.17.4

Question

I cannot print any recipe from my installed « Gourmet Recipe Manager ». I keep getting the following error messages. Is this a Ubuntu problem or a specific problem with the Gourmet software ?

My file python.py reads:

sublabel=_("To print, activate a plugin that provides printing support, such as the 'Printing & PDF export' plugin."), )

Where can I get this Printing & PDF export' plugin ?

What's the solution to fix this ?

Thanks in advance.

I see that PDF export works out-the-box in Ubuntu 14.04 LTS (EOL or ESM now) and 16.04 LTS.
The Ubuntu 16.04 LTS has needed file print_plugin.py in place.

But Ubuntu 18.04 LTS and 20.04 LTS do not have this file.
So it is a packaging bug. I reported it as bug 1851016 affecting these Ubuntu versions.

If you really need this functionality you can download packages from 16.04 LTS repository with commands below:

cd ~/Downloads
wget http://archive.ubuntu.com/ubuntu/pool/universe/p/pillow/python-imaging_3.1.2-0ubuntu1.4_all.deb
wget http://archive.ubuntu.com/ubuntu/pool/universe/g/gourmet/gourmet_0.17.4-3_all.deb
sudo apt install ./python-imaging_3.1.2-0ubuntu1.4_all.deb
sudo apt install ./gourmet_0.17.4-3_all.deb

and then pin/lock gourmet package version:

cat <<EOF | sudo tee /etc/apt/preferences.d/pin-gourmet
Package: gourmet
Pin: version 0.17.4-3
Pin-Priority: 1337
EOF

Then you should open Gourmet, click Settings → Plugins, go to Importer/Exporter tab and enable Printing & PDF export plugin if it is not enabled.

Then printing will work as expected.
