Enable Network Printer Sharing with Ubuntu Linux computers

Having a shared printer within a computer network is a nice thing to have. Since all computers within the network can access a remote printer to print documents. Maintenance cost is much more cheaper and easier since you only need to service only a single printer within a network.

Here’s how to enable Printer sharing with Ubuntu (or other Linux based computers) through GNOME :

At the computer with the printer

Administer Printers Ubuntu
  • First at the Desktop, go to System->Administration->Printing. A dialog will appear
  • Go to Server Settings, and check the “Share published printers connected to this system” checkbox

    Administer Printers Ubuntu

  • You may, optionally select “Allow users to cancel any job”
  • Click Apply, and close the dialog

At the client computer(s)

Network Printer Sharing Ubuntu, using Samba

  • From the Desktop, go to System->Administration->Printing. A dialog will appear
  • Check “Show shared printers from other systems” checkbox. Click Apply
  • Repeat the first step, this time click “Refresh Printer Queues” button. You shall see the list of shared printer from the server computer
  • Repeat this on other computers on the network to share the printer

That is all to it! Now you can print documents across your computer network.
