A roll-to-roll printer, comprising:

• a first holding mechanism;
• a second holding mechanism;
• a printing mechanism;
• a third holding mechanism;
• and
• a carrying mechanism;
• wherein the first holding mechanism is configured to rotatably support a substrate stored in a rolled form;
• the second holding mechanism is provided above the first holding mechanism, and is configured to continuously collect a protective film which is peeled off from a surface of the substrate;
• the printing mechanism is provided in front of the first holding mechanism;
• the printing mechanism is provided with a printing platform;
• the printing platform is configured to hold the substrate with the protective film peeled off;
• and the substrate is configured to be continuously supported on the first holding mechanism in the rolled form, and continuously transferred across the printing platform from the first holding mechanism toward a front of the printing platform;
• the third holding mechanism is provided in front of the printing platform, and is configured to rotatably support a transfer film stored in a rolled form;
• the carrying mechanism is provided in front of the printing platform, and is configured to attach the transfer film to a printed surface of the substrate to continuously carry the transfer film and the substrate;
• the carrying mechanism is provided with a first clamping roller and a second clamping roller opposite to each other;
• at least one of the first clamping roller and the second clamping roller is configured to be driven by a drive device to rotate;
• and the first clamping roller and the second clamping roller are configured to hold the transfer film transferred from the third holding mechanism and a printed substrate;
• and
• the second clamping roller is provided with an accommodating hole extending in an axial direction of the second clamping roller;
• and the accommodating hole is configured to accommodate a heating member.
