I'm looking to purchase bulk quantities of both black and color toner for our printing operations. We're interested in high-quality products that are compatible with a range of printers, and it would be great to have various options available. Could you provide details on your available products, including pricing, packaging, and any bulk order discounts? Additionally, I'd like to know about the lead times for delivery and any minimum order requirements. If you have samples or specifications, that would be very helpful for us as we evaluate our options. We're aiming to establish a long-term relationship, so any additional information about your company's quality control and support services would be appreciated. Looking forward to your prompt response.
