According to src/java.desktop/share/classes/sun/print/PSPrinterJob.java.
In case of desktop printing feature calls following command.
* With banner page
/usr/bin/lp -c -dinfoprt -tJava Printing -o job-sheets=standard /tmp/javaprint324098563
7403973305.ps
* Without banner page
/usr/bin/lp -c -dinfoprt -tJava Printing -o nobanner /tmp/javaprint17598598054218192566.ps
(Note: "infoprt" is printer name)

AIX has two printing subsystem (AIX and SystemV)
According to man page of "lp" command [1].
If printing subsystem is configured for AIX and printer is configured by LPD,
printer backend program is ignored.
If printing system is configured for AIX, printer is configured with printer driver.
Printer driver could not handle "-o job-sheets=standard" or "-o nobanner " option properly.

To avoid this situation,
"lpr" command [2] should be used instead of "lp" on AIX.
