A pneumatic nozzle‐based printing technique that can control the crystallization of small molecule organic semiconductor thin films during deposition is reported. By tuning the printing speed and the substrate temperature, large‐sized organic crystals are grown along the printing direction, resulting in field‐effect mobility enhancement by 50 times compared to spin‐coated films for 6,13‐bis(triisopropylsilylethynyl)‐pentacene. Furthermore, silver electrodes using the technique to fabricate printed flexible inverters with a gain as high as 16 are printed.
