Firefox (flatpak) is crashing when trying to print a document
I am running Firefox (Flatpak) on Debian 12 and I use a Nelko thermal label printer. I had installed nelko-printer-driver previously and had no issues printing on Firefox but, due to an issue with Debian, I had to reinstall Debian 12. Now, when I try to print a document then Firefox immediately crashes. I have tried:
- Uninstalling the Flatpak and deleting app data
- Help > More Troubleshooting... > Clear Saved Print Settings
- about:config > Reset modified printer settings
- Uninstalled/reinstalled nelko-printer-driver
- Restarted

Try Firefox from Mozilla. Download, unzip, and run firefox-bin from the folder and see if you have the same issue.

What desktop? X11 or Wayland? Have you tried testing on a VM or usb live stick?
Okay, it looks like the issue is down to the Flatpak because the .deb worked just fine.
The crash is inside the printer library (libcups). Make sure all your system and flatpak packages are up to date:
sudo apt update
sudo apt upgrade
flatpak update
Flatpak needs a portal for printing:
sudo apt install xdg-desktop-portal
Apt and Flatpak are both up-to-date. xdg-desktop-portal was also already installed:
xdg-desktop-portal is already the newest version (1.16.0-2).

I have the same problem as well. Both the Flathub flatpak of Thunderbird and Firefox crash when you select "Print" from the menu or use the keyboard shortcut "Ctrl + P". No error is given, I can't find much in the system logs either. Wasn't a problem a month back, if I remember correctly.

I don't encounter this crash with flatpak on Ubuntu 23.04 using the default or system print dialog.
I have the following portal packages installed:
xdg-dbus-proxy
xdg-desktop-portal
xdg-desktop-portal-gnome
xdg-desktop-portal-gtk
xdg-user-dirs
xdg-user-dirs-gtk
xdg-utils
Does it still happen when there are no physical printers connected?
Yes, it does. It looks like this is a known issue.

I use X11 (due to my NVIDIA drivers), and it crashes just the same.
Let me install the flatpak and see what happens.
I had no issues printing with the Flatpak version. see screenshot Sounds like a job for strace to see what's happening when Firefox goes boom.
