Abstract:
Systems and methods for printing are described. One example is a tension module for a printer including a throughput roller including a length to diameter ratio of at least 10:1 and a material on the surface thereof having a friction coefficient value less than 1. In addition, the module includes a plurality of pinch rollers arranged parallel to the throughput roller and, the pinch rollers supporting the throughput roller and providing a pressure on a print medium when passed along the throughput roller. Further, the module includes a motor to rotate the throughput roller. Still further, the module includes a tension lever including a plurality of stops, each of the stops being associated with one of a plurality of tension settings. Manipulation of the tension lever between two of the stops adjusts the pressure between the throughput roller and the pinch rollers on the print medium.
