To print only select cells or non-adjacent columns in Google Sheets, you can utilize the “Print Area” feature. First, select the cells or columns you want to print while holding down the command key. Then, go to “File” in the menu, choose “Print,” and select “Selected cells” under the “Print” section. Ensure the correct cells are highlighted in the print preview. This method allows you to print specific, non-adjacent cells or columns, and holding down the command key helps you select multiple areas. Adjust the print settings as needed to tailor the printed output to your preferences.
