I am trying to attach a dj 560 to my AlphaStation 200 4/100.  It is running
OSF/1 V3.2.  I have told the lprsetup program that it is a la75of printer 
(at DEC's recommendation).  It now prints text files OK but won't print
PS files either if I send them directly to the printer (lpr file.ps) or
convert them to djet500, cdj550, deskjet or cdeskjet formats using ghostscript.

It spews out a message saying 'file contains unprintable data' and logs it.
Here is a sample of the log:

I want to be able to print colour PS files on this printer.  How do I set it
up?  Your help would be most appreciated.
