To add a printer to your Mac Mini, you can follow these steps based on whether you want to connect via Wi-Fi or USB:

**Connecting a printer wirelessly (Wi-Fi):**

1. **Connect the printer to your Wi-Fi network.**
– Most modern printers with a screen allow you to go to the Wi-Fi setup menu on the printer itself to select your home Wi-Fi network and enter the password.
– If your printer doesn’t have a screen, you may need to use the printer manufacturer’s app (such as HP Smart or Epson Smart Panel) to connect the printer to your Wi-Fi.
– If your printer supports WPS, you can press the WPS button on the printer and your router to connect automatically[1][2][3].

2. **Add the printer on your Mac Mini:**
– Click the **Apple menu** (top-left corner).
– Go to **System Settings** (or **System Preferences** on older macOS versions).
– Select **Printers & Scanners**.
– Click **Add Printer or Scanner** (a plus “+” button).
– Your Mac Mini will search for printers on the same Wi-Fi network. Select your printer from the list and click **Add**[1][2][3].

3. **Print normally using the newly added printer.**
– If the printer supports AirPrint, it will show up automatically and doesn’t require extra drivers[3].

**Connecting a printer via USB:**

1. Plug your printer’s USB cable into your Mac Mini.
2. Open **System Preferences > Printers & Scanners**.
3. Click the **+** sign, select your printer under the Default tab (it should show a “USB” kind), and click **Add**[4].

**Adding a printer by IP address (advanced option):**

1. Find your printer’s IP address (check the printer’s network settings or manual).
2. Go to **System Preferences > Printers & Scanners**, click **+**, then select the **IP** tab (blue globe icon).
3. Enter the IP address of the printer and follow prompts to add it[4].

This should cover all typical ways to add a printer to your Mac Mini, whether wireless or direct connection[1][2][3][4].
