Don't sell outdoor signage made with this printer unless it is temporary, it's immoral. Use it for indoor signage and banners; you mentioned cut vinyl, use that for making long lasting outdoor signage. If you need outdoor signage that is printed there are so many good wholesale merchant members here that you could sub that printing work out to, eliminate the hassle, make good profit, not stock all that inventory and sell your customer a quality product. If your demand is high you will have plenty of dough to purchase your new printer.
