Methods for converting an image to source script are provided. Generally applied to thermal printers, the methods may assist users in reproducing or amending a label without actual source script. In one embodiment, a mobile device comprising a software application may be able to scan an image, for example a barcode label. The software application may use an image processing library to recognize smart object fields in the captured image, including text, barcodes, image and shapes and then may translate the smart object information to a printing language script automatically. The application may provide the capability to a user to adjust the parameters specific to each of the identified smart objects. Once the user makes the necessary changes, a script file may be generated based on the updated smart object information. Then, the label may be sent to a printer from the application itself.
