How to printer screen on a Mac - answering your questions

"Printing the screen", commonly known as taking a screenshot, is a straightforward process on a Mac. MacOS offers several methods to capture your screen, whether you need the entire screen, a specific window, or just a portion of it. Here's a step by step guide:

Capturing the Entire Screen
1. Press `Shift + Command + 3`: This key combination will capture the entire screen.
2. Find the Screenshot: After pressing these keys, you'll hear a camera shutter sound (if your sound is on), indicating that the screenshot has been taken. The screenshot will automatically be saved to your desktop by default, as a `.png` file.

Capturing a Portion of the Screen
1. Press `Shift + Command + 4`: This turns your cursor into a crosshair.
2. Select the Area: Click and drag to select the area of the screen you want to capture. Release the mouse button or trackpad to take the screenshot.
3. Locating the Screenshot: Like the full-screen capture, the file will be saved automatically to your desktop.

Capturing a Specific Window
1. Press `Shift + Command + 4`, then release these keys.
2. Press the Spacebar: The cursor will change to a camera icon.
3. Select the Window: Move the camera icon over the window you want to capture. The window will be highlighted. Click to take the screenshot.
4. Accessing the Screenshot: The image will be saved on your desktop.

Using Screenshot Utility
MacOS Mojave and later versions come with a Screenshot utility that offers more options.
1. Press `Shift + Command + 5` to open the Screenshot utility.
2. Choose Your Screenshot Type: You'll see options for capturing the entire screen, a window, or a selected portion of the screen. There are also options to record your screen.
3. Take the Screenshot: Click on one of the options and follow the prompts.
4. Editing and Saving: After capturing, a thumbnail appears in the corner of your screen. Click it to edit the screenshot or wait for it to save automatically to your desktop.

Saving Screenshots to Clipboard
- To save any of the above screenshots to your clipboard instead of as a file, add the `Control` key to any of the combinations. For example, `Control + Shift + Command + 3` captures the entire screen and saves it to the clipboard. You can then paste it into a document or image editor.

Additional Tips
- Change Default Save Location: If you don't want your screenshots to clutter your desktop, you can change the default save location using the Screenshot utility or Terminal commands.
- Editing Screenshots: Use Preview or any image editing software to edit your screenshots.
- File Format: Screenshots are saved in `.png` format by default, but this can be changed using Terminal commands.
