What network utility on a MAC can help me see what devices, printers are available, listening etc on my wifi. Netstat does not seem to show me my printer or Android device. For example,

My macbook pro with ip address 10.1.140.255 but I can't see my Android phone with ip 10.1.140.77 or a printer on 10.1.140.95.

Try arp -a instead. Netstat doesn't scan the network, it just provides information about your own device's connection to the network.

Edit: Try ifconfig | grep broadcast | arp -a

When you're on LAN, connecting to an IP involves resolving the IP into a mac address. ARP keeps a cache of all resolved IP addresses. Doing a broadcast ping indirectly triggers a resolution for all IPs on the network.

Considering that some of your devices may be passively just sitting there with no active connections to your computer, you can't find them by examining your computer; you'll have to go actively looking for them. That typically means a network scanner.

Here's a list: https://www.softwaretestinghelp.com/network-scanning-tools/

I like Nmap (https://nmap.org) with the Zenmap GUI (https://nmap.org/zenmap)

Just make sure you do this in your own network. Scanning somebody else's network will trigger alarms and is more than likely illegal.
