You can configure Cura to send your sliced print file directly to the printer but first you will need to configure a connection from the printer profile in Cura to the instance of OctoPrint/OctoPi that is controlling the printer.

In Cura, go to Settings > Printer > Manage Printers...:

Select your printer from the list
Click Activate
Click Connect to OctoPrint

A new dialog will appear listing the available OctoPrint instances:

Click Add to get another dialog where you can manually configure an OctoPrint connection:

Enter an Instance Name that describes the new connection
Enter a the OctoPrint/OctoPi hostname (eg octopi.local) or its IP address in the IP Address or Hostname field
Enter the Port Number (by default OctoPrint/OctoPi uses 80 but if you are running it on your desktop it may be using port 5000)
Enter the Path (by default it will be a single /)
Click Ok

The list of OctoPrint instances should now include the instance you just created:

Select the instance and then click the Open in browser button which should open your OctoPrint server in a browser
In OctoPrint go to Settings and select API and copy the API Key
Paste the API key in the field called API Key in the Cura
