Jan,

thanks for the files. Looking into the input file (test.ps) reveals that the 
page setup section of the (only) page contains the statement
595 842 /a4 setpagesize
which forces the printer to use an A4 page size ignoring whatever  the 
pstops filter might have inserted in the global setup section. Thus the 
PostScript job itself cancels any fit-to-page implementation by the pstops 
filter.
Moreover, the pstops filter does the page fitting by computing the scale 
factor for page fitting from both the specified media size (job options of 
default page size from the PPD) and the job's bounding box. As both of them 
specify A4 page size, there is in fact no scaling to do.

What did you expect instead?
