Is there any prohibition in my friend's work printing labels for wine bottles?

If a woman does not directly engage in a forbidden act, nor directly assist in it, then there is no harm for her in it, nor in what she earns from it. The presence of wine stickers with the company does not affect her, as long as she does not undertake their printing. However, if her work requires her to print materials related to wine and other forbidden things, and she is unable to refrain from doing so, then this work is not permissible for her, due to the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
