wholesale on demand printing is a business model where entrepreneurs sell custom-printed products, such as T-shirts, mugs, or posters, without holding inventory. In this model, products are printed on demand, only when an order is placed. Wholesale on demand printing suppliers handle the printing and fulfillment processes, allowing dropshippers to offer a wide variety of customized products with minimal upfront investment. This model is especially popular in the apparel and merchandise industries, as it allows for personalized items without the need for mass production.
