Whichever way you went about it, you should now see Printers in the System menu and adding a Printer should be fairly straight-forward. If buying new, check the documentation on the box and / or the manufacturer’s website for Linux compatibility.
Ensure the printer is plugged-in, connected to the computer and powered-on. In many cases, that’s all you need to do – the printer will be automatically recognized and configured.
The green circle check mark indicates this is the default printer
For more information and options, right-click the printer’s icon and select Properties
If Printers didn’t recognize your printer, click the [Add] button. Or, go to Server > New > Printer

Allow Printers to search for printer drivers
Make any necessary changes to the printer description and click the [Apply] button
Or, visit your printer manufacturer’s website to find and download an appropriate Linux driver or PPD (PostScript Printer Description).
