Laserwriter printing

[snelson@icaen.uiowa.edu (Steve Nelson)]

Laserwriter help?  2 questions:

System/Hardware  GS/OS system 6.0.1,  IIGS Rom 1 + 4Meg RAM + ZipGS 8/64

Using a GS/OS pgm like AWGS, or NDA like EGOed,Hermes, etc. I can print
via Appletalk to a LaserWriter II NT, but I can not get a printout on
a LaserWriter 12/640  (after the preparing data, status, etc. messages
a get a brief alert like % % flushing to end of file % %, or something
to that effect).  From P8 and the imagewriter emulator (v1.6) downloaded
into each printer, printing is fine.  It is just GS/OS postscript printing
which doesn't work.  Obviously I am using the net printer control panel
to select printers etc. with no problem.  Does anyone have an explanation
why the newer 12/640 does not work with GS/OS?  Is there a solution?

Which brings up question 2:  I thought I would look at a postscript file
and manipulate it and use Laserbeam to test the 12/640.  But I have forgotten
how to print to a file.  I have a driver for postscript (named PostscriptF
which is a copy of the LaserWriter driver) and have chosen PostscriptF as
a direct connect printer, and I know I am supposed to hold a key down (F?)
when I click the OK button in the print dialogue, but what key?  I've used
f, ctrl-f, shift-f, apple-f, option-f, etc. to no avail.  Postscript.000
etc. files do NOT show up in the drivers folder.  I get a error message
instead.  I know I did this successfully in the past, but now that I want
to do it I can't remember how.  Help, please?

Thanks, and Happy New Year Everbody!
