How to press tofu 
Determine if you need to press the tofu at all. 
Silken tofu does not need pressing, as it is softer and used more often in blended dishes. Firm and extra firm tofu almost always needs to be pressed, as it's density allows it to keep more water when cooking.

Choose from:
 1). Press the tofu to incorporate it into a blend. The difference between firm and semi firm tofu will depend on the brand and make.
 2). For more delicate, more traditional tofu recipes, however, pressing may be necessary. Firmness is measured in pounds or more in grams.
 3). On the flip side, tofu that fits tightly into the microwave doesn't need pressing at all. For example, cheese or bread is lightly covered in tofu to withstand in the microwave.
 4). Whether or not to press tofu depends, more often than not, on how you plan to cook it : Blending, mixing, or raw: don't press. Frying, grilling, baking: press as much water out as possible.
The answer is:
4).
