I'm looking to purchase POS paper and would like to get some detailed pricing info. Specifically, I'm interested in the rolls that are 57mm wide and 50mm in diameter. Please provide the best company price for these products, along with any available options or bulk discounts you might offer. Additionally, it would be helpful to know about the quality of paper you provide, including any specifications or certifications. If possible, please also share lead times for delivery and payment terms. I'm eager to establish a solid working relationship, so any insights into your product range and pricing structure would be greatly appreciated.
