Set the default printer
If you have more than one printer available, you can select which will be your default printer. You may want to pick the printer you use most often.
Click the icon at the far right of the menu bar and select System Settings.
Right click your desired default printer from the list of available printers, and click Set as Default.
When you print in an application, the default printer is automatically used, unless you choose a different printer for that specific print job.
