If you are new to ChaletOS, this tutorial will show you how to add, connect and install printer driver on ChaletOS 16.04. I am using Brother MFC-9330 CDW laser printer connected to my network. The steps is pretty much the same with any other printer. Step 1 is to connect your ChaletOS to the network. Then, open Settings | Printer.
Click Add and select Printer
Since here we want to connect to network printer, click the Network printer and you should see your network printers listed here. Click one of the printer you want to connect and press Forward.
Now select the printer driver. ChaletOS should recognize your driver automatically. Select gutenprint driver, and it will download list of supported printers.
Once completed, you can start using your printer from ChaletOS.
