### Install Packages ###
echo "### Step 2: Initialize the RPi and Install Packages ###"

# Sync RPI system
sudo apt update -y && sudo apt upgrade -y

# Install
sudo apt install -y cups samba

# Install the CUPS print server and SAMBA file sharing packages. This will take a several additional minutes.

# Add an administrative user for the printer. Replace pi with your username
sudo usermod -a -G lpadmin $USER

sudo systemctl restart cups

### Configure SAMBA ###
