It is still possible for some filter -- most likely from HP -- to add PJL instructions=20 informing the printer of the current date. Of course if you send generic postscript as generated by a unix application direct without a filter then the PJL can't get added. But on the other hand some features of some printers can only=20 be accessed via PJL. Malcolm Kay
