Installing a printer in OS X

I use a wireless printer configured with a dynamic IP address, so I often have to re-install it when its IP address changes. 

Installing a wireless printer in OS X is straightforward.

Go to System Preferences/Printers & Scanners and click the "+" button for you to add a printer.

Open the IP tab.

Before starting the installation, get the IP address for your device from your router's configuration page (check the "Connected Devices" page) .

Refresh the page to make sure you have the correct IP address.

Some routers have a functionality called DHCP Reservation, allowing you to assign a static IP to a certain device.

Sadly, it's not supported in my case; if so, you could see an outdated network configuration until you refresh the page.

Ping the IP address you see in your router's page from Terminal. Try to reach it with your browser, as well, and open the printer's configuration page.

If you have a positive response from the above procedures, you're good to go.

Enter the recovered IP into the "Address" field.

Wait for a second. 

If the process is successful, you should see the correct name of your printer in the Use: field.

This might sometimes require a while, as the printer could be in sleep mode.

If the process returns a "Generic PostScript Printer", abort the process and start over.

That printer might work as well, but it's not guaranteed.

After a while, you should be able to see your specific printer model in the configuration page. If you keep getting a "Generic PostScript Printer", restart your router.

At that point, click Add for your printer to be successfully setup.
