Xerox 701P21091 manual Overriding PDL commands

PDL principles and procedures

In addition to typeface, style, and size, a font can be defined by its orientation:

•Landscape

•Portrait

•Inverse landscape

•Inverse portrait

Custom fonts, signatures, and logos may be ordered from Xerox through your sales representative.

Overriding PDL commands

The system default values are listed in the “PDL command and DJDE summary” appendix. The printing system uses the defaults for parameters you do not specify in the JSL. When you are creating a JSL, you do not have to code the command parameters for which your jobs specify the defaults.

NOTE: Some parameters have no defaults. If you do not specify a value for these, they are not included in the job description. DJDEs do not have default values.

The coding may be further simplified by placing commands common to more than one job at the catalog command level. The PDL processor evaluates user coded commands and applies the highest priority, error free definition to the job for printing. This process, termed the “hierarchy of replacement,” is discussed in the subsequent paragraphs and illustrated in the “Command override sequence” figure.

The following figure shows a diagram of the command override sequence.
