[socket] Enable Printing system by default

[ovari]

Please set socket=cups to true. This should enable users to print emails.

What do you think?

Thank you

Firefox have this problem a few months ago but now works but not Thunderbird..

@ovari Does it work for you with socket=cups enabled? It doesn't work for me.
For example, Libreoffice doesn't have this option enabled and printing works..

[elgabo86]

@Erick555 This commit resolves printing in Firefox and i think Thunderbird needs the same.

[Erick555]

@elgabo86 does printing work if you switch to system dialog?

For example, Libreoffice doesn't have this option enabled and printing works..

On other hand printing in LO doesn't work for many people out of the box (including myself), see flathub/org.libreoffice.LibreOffice#90 . Printing is complicated issue as there are so many ways to connect to printer (usb, local network, remote network, etc.).

[elgabo86]

@Erick555 no it doesn't work with the system dialog.

Firefox (default and system dialog) and libreoffice can print with a HP printer on USB and a Brother tested with rj45 and wifi.

[elgabo86]

When I choose the system dialog in Firefox i've got this : (and works)

But with Thunderbird, i've got the portal dialog : (And doesn't work)

[ovari]

Does it work for you with socket=cups enabled? It doesn't work for me.

@elgabo86 Unfortunately it doesn't work here either.

[Erick555]

@ovari @elgabo86 could you test this version?

Testing now, can you please advise the instruction to uninstall?

Thank you

[ovari]

@Erick555 how do we open the test version of Thunderbird now that it is installed? Thank you

[elgabo86]

@Erick555 Sadly this version doesn't work too..

@ovari

flatpak run org.mozilla.Thunderbird --branch=thunderbird-origin to run this version
flatpak uninstall org.mozilla.Thunderbird and select the beta version to remove it

[elgabo86]

@Erick555 Just in case, I tested Thunderbird from the flatpak fedora repository and printing works.

[ovari]

could you test this version?

Yes, tested with Linux Mint 20.3 Cinnamon and successfully printed to both a physical printer and a Virtual PDF printer. Thank you very much.

There were two interesting observations:

1. The print dialog came up and when Print button was clicked, the System Print Dialog then came up. Is there a way to enable printing without showing the System Print Dialog (unless it is clicked on)?
2. There were errors shown in the Terminal, output shown below:

$ flatpak run org.mozilla.Thunderbird --branch=thunderbird-origin

However, at least it is now possible to print with Thunderbird.

Thank you once again.

[Erick555]

@Erick555 Sadly this version doesn't work too..

@elgabo86 could you re-check it with recent update. I added some patch that should help.

[elgabo86]

@Erick555

It now works with the last update. Thank you !
