How to share a printer on a network in Ubuntu (GNOME)

Sharing a printer on a network in Ubuntu provides a central point for multiple devices to send print jobs, reducing hardware costs and simplifying management. The Common UNIX Printing System (CUPS) handles core printing functions across different platforms, making the printing process consistent and universally accessible. Its robust architecture allows seamless connectivity through port 631 while ensuring reliable performance.

The CUPS environment integrates with various printer drivers and supports both local and remote printing. By leveraging Ubuntu’s default tools, administrators can handle printer discovery, permissions, and network firewall rules with minimal complexity. This combination of CUPS services and Ubuntu’s user interface guarantees efficient workflow for small offices, enterprise settings, or home networks.

Network security and resource allocation are key considerations when sharing printers. Adjusting firewall settings, confirming service status, and properly configuring sharing options in the Settings application all help maintain a secure environment. With these elements in place, users across different operating systems can reliably access the printer without driver incompatibility issues.

1. Open the Settings application.
2. Navigate to the Printers section from the sidebar menu.
3. Select the printer you want to share.
4. Click on Additional Printer Settings.
5. Right-click the printer and choose Properties.
6. Go to the Policies tab.
7. Check the box labeled Shared.
8. Save the changes.
9. Ensure that firewall settings allow printer sharing on port 631.

   $ sudo ufw allow 631/tcp

   Firewall settings are crucial to permit external devices to communicate with the shared printer. Ensure you modify firewall rules with caution.

10. Share the printer’s network address with other users, typically in the format hostname:631/printers/printer_name.
