Spooler Job That Prints a Banner Page Followed by an
Application-Generated Job (Application Does Not Specify
Printer Language)
The following example demonstrates a spooling application
that prints a banner page. The application was not created
with a PJL-ready driver, so it does not begin and end with
UEL commands, or specify the printer language—the
printer implicitly switches to the correct printer language.
