printing from a Mac to a 4019 laser printer

[Jane Shilling RBA5 7278]

	Has anyone been able to print from a Macintosh to a
4019 IBM laser printer?  
	I have been having problems setting this up.  Our laser 
printer is connected via the parallel port to an x-station.  The
host is a RISC 6000/530 running 3002 with AIX 3.1.  The printer
is set up as a PostScript printer.  The trouble is that it doesn't
print files from the Mac, which I think is due to it not understanding
the PostScript that is generated.  The Mac is connected on an Apple Talk
Network via a multigate (apple talk - ethernet converter) to a Sun4/260.
The 530 is connected via ethernet to the Sun4.
	We have had success printing PostScript files which have 
been generated via d2ps (converting a dvi file to PostScript).
	Does anyone have any ideas on how to get this working? 

	Thanks,
