No, the pdtops filter gets called (as it converts from
application/postscript to 
application/vnd.cups-postscript), but the pstops filter itself
suppresses the PAGE: messages
if the printer's PPD contains at least on filter statement (it the
assumes the ppd-specified
filter(s) create these messages).
