"bang" commands are commands that can be included in a data stream that will change the behavior of Print Wizard in printing a portion of a file. Bang commands are discussed in detail in the Print Wizard manual.
You can split your data into multiple sections to be processed separate from other sections by including bang commands directly in the data stream. As an example, if I wanted to create a PDF of part of a file, fax another part of a file and email another part of a file, I could do this within one print job with bang commands.
