Also, you can be discharged from a hospital - and you can say тебя выписали из больницы. And when doing so the doctor can prescribe you a medicine - "выписать" лекарство.
You can also выписать себе журнал (to subscribe, although more often you will hear подписаться на журнал).
Also an artist can work very hard on some details of a portrait, in this case you can say он тщательно выписывает детали.
