A printing processor receives print job instructions to combine variable printing information and fixed data to build a print job to be printed using a printing engine. The variable printing information is unrasterized-type data. The printing processor evaluates the print job instructions to determine whether the configuration of the variable printing information is compatible with configurations of different fixed data forms (the fixed data forms are rasterized-type data). The graphic user interface displays menu selections of only the fixed data forms determined to be compatible with the configuration of the variable printing information.
