Kim, I agree with the others, you should bill her for the prints. If she refuses to pay, then end the business with her. She can't get it done cheaper than you do if you charge her the actual cost, so she'll come running back and beg you, I bet. She may try to get another to do it, but that person will get fed up with her in no time!

When John worked for a friend who owns a Bar, this guy wanted him to print A3 posters, but he was a really nice guy and bought the printer, as these posters were the only jobs he needed it for.

Good luck! I hope new customers will come your way!
