Dynamic pattern transfer printing systems and method are provided, which decouple the design of the trench patterns on a source substrate for pattern transfer printing, from the resulting metallic paste lines patterns transferred to a receiving substrate, such as PV cells. The receiving substrate may be moved forward (along the scanning direction of the laser illumination used to transfer the paste from the trenches onto the receiving substrate) to reduce the pattern pitch with respect to the source substrate, and/or the receiving substrate may be moved backward (against the scanning direction) to increase the pattern pitch with respect to the source substrate. For example, dynamic pattern transfer printing may be used to accommodate different widths of the substrates for more effective pattern transfer, and/or to enable one-to-many pattern transfer technologies with high wafer throughput. Also, pattern transfer sheet with separate multiple groups of trenches are provided.
