An information processing system includes a generation unit and a reconstruction unit. The generation unit generates a data source including data to be referred to at a time of printing for a variable portion in which data to be referred to is variable for each record. The reconstruction unit acquires the data source and reconstructs print data that is variable for each record. The generation unit executes processing of determining a largest size based on a size of data to be referred to for the variable portion to generate stub data of the determined size, of generating the print data by using the stub data, and of generating the data source for each record. The reconstruction unit executes processing of reconstructing the print data by overwriting the stub data in the print data with the data in the acquired data source.
