When you print text or graphics, SAS needs to know where the output should go, how it should be written, and how the output should look. Universal Printing is the default printing mechanism in UNIX. Universal Printing generates both PostScript and PCL files in the SAS windowing environment. For more detailed information about Universal Printing, see SAS Language Reference: Concepts .
Forms printing is an older method of text printing available from SAS. It involves using the FORM subsystem, which consists of the Form window. For detailed information, see FORMS printing in SAS Language Reference: Dictionary .
If you are printing graphics, the output is controlled by native SAS/GRAPH drivers. Refer to the online help for SAS/GRAPH for detailed information about native SAS/GRAPH drivers.
