For the purposes of taking Discovering the Daisho of Water, do abilities granted by invests count as printed abilities? For example, can I use the Fear 5 from an invested Isawa Orinoko? Could I also, perhaps, use the Range 3 granted by Guidance in War?
Discovering the Daisho of Water: "Battle: Straighten your target Personality. If he has 3 or more Personal Honor, or is Lion Clan, you may take an additional action to use an ability printed on the Personality."
Isawa Orinoko: "Invest : Give Orinoko three +1F/+1C tokens, then permanently give her Conqueror and the ability, "Fire Battle: Fear 5." This Invest cost cannot be reduced."
Guidance in War: "This Spell's Invest effects last while it remains attached to the Shugenja. Invest : This Shugenja has Cavalry. Invest : This Shugenja has Conqueror. Invest : This Shugenja has +2F. Invest : This Shugenja has the ability, "Battle: Ranged 3 Attack.""

If they are actually printed on the Personality, yes. Orinoko's invested Fear 5 is a Printed ability. The Ranged 3 granted by Guidance in War, however, is printed on Guidance in War, not the Personality to whom it is attached.
