Printing Press Letters, more purpose

Looking around my island I see that for one reason or another I have upgraded most of my buildings to level five and eagerly await level six... Except for my poor lonely Lettersmith. Stuck at level 1 from the day he was built with no purpose other than the occasional tome he is developing quite the inferiority complex surrounded by such grand neighbors. I am not saying that I want to divert more iron on him rather than weapons, but perhaps in a future provisions house recipe we can use these printing press letters for something before they overflow out of my storehouses. Maybe on the new Steak Recipe buff? Have to stamp USDA Prime on it somehow.
