Antonis, thanks for answering.
My system is as follows:
OS 9.2.1, PS 6.01, 1,5 Gig Ram, 1 Gig allocated to PS.
PS never freezes, even if I have working-files (virtual files ) of 3 
Gig. I can print 2 Gig RGB files via the Epson driver on my 7500, the 
system never freezes, but it may freeze if I print a 150 MB file via 
the Piezo driver on my 1160.
My system HD is a bit fragmented, but the biggest not 
fragmented part is about 5 gig.
If that is of interest, one should assume, that the piezo driver 
spools to the system HD, though PS and the Epson Driver have 
separated scratch disks ??
Thanks Bernd

PS the main question seems to be whether the Piezio drv.  does or does not 
spool. If I remember it well J. Cone once stated, that it does not spool. But why 
then does it delete sometimes huge amounts of data before it starts printing 
???
