I'm interested in sourcing high-quality white A4 thermal paper rolls for our ongoing projects. We require thermal paper that meets industry standards for both printing clarity and durability. The rolls should be compatible with a variety of printing devices, ensuring optimal performance and minimal downtime. Additionally, could you provide information on your available quantities, pricing tiers for bulk orders, and any customization options you might offer? We're keen on establishing a reliable supply chain, so lead times and shipping details would also be beneficial. Looking forward to your prompt response!
