Per https://phabricator.services.mozilla.com/D139594#4621637:
I have a general problem on the Canon, the TS-3350 and the MB2100.
I can't print in black and white!
This is valid for thunderbird and Firefox and Firefox-esr.
To print in black and white on linux (with a Canon with the proprietary driver) you have to enable or disable a flag in GtkPrintSettings:
gboolean color = gtk_print_settings_get_use_color (settings, color);
gtk_print_settings_set (settings, "cups-CNGrayscale", (color ? "False" : "True"));
