If you want to View or Print all formulas in excel cell, you can select that cell and view the formula in formula bar. You can also view the formula of selected cell by pressing the F2 Key.
But if you want to see the formulas in a sheet, you can go to Formulas Tab and click on Show Formulas. It will show all the formulas in that sheet instead of formula results. You can also use the keyboard shortcut [Ctrl+~] for this function. If you print that sheet same formula will be printed.
