Printing not working with Ubuntu 24.04

[rmerriam]

Attempting to print shows a dialog "Error Failed to Enumerate Printers".

The following is seen from typora -dev:

_Gtk-Message: 15:11:23.515: Failed to load module "appmenu-gtk-module" Gtk-Message: 15:11:23.516: Not loading module "atk-bridge": The functionality is provided by GTK natively.

This is register version 1.9.3. and the OS Ubuntu 24.04. The error occurs for all files and is not new.

relates #6209

Please try https://askubuntu.com/questions/886488/application-installed-as-snap-package-cant-see-printer

Or use the deb / binary version of Typora, instead of snap version

Trying the fix from the link doesn't work.

sudo snap connect typora:cups-control :cups-control
error: snap "typora" has no plug named "cups-control"

I uninstalled the snap version, installed the deb version, reentered license, and tried to print:

$ typora [64771:0218/140916.620192:ERROR:nss_util.cc(357)] After loading Root Certs, loaded==false: NSS error code: -8018 Segmentation fault (core dumped)

Seems to by fixed in current Typora version 1.10.8. Isue may be closed.
