I do it like this (actually I use EPDF format with PDF, but the
principle is the same):

Start the DSSSL driver something like this:

<!DOCTYPE style-sheet PUBLIC "-//James Clark//DTD DSSSL Style Sheet//EN" [
<!ENTITY %  output.print.pdf "IGNORE">
<!ENTITY %  output.print.eps "IGNORE">
<!ENTITY % html "IGNORE">
<![%html;[
<!ENTITY % print "IGNORE">
<!ENTITY docbook.dsl SYSTEM "/usr/lib/sgml/docbook/html/docbook.dsl" CDATA dsssl>
]]>
<!ENTITY % print "INCLUDE">
<![%print;[
<!ENTITY docbook.dsl SYSTEM "/usr/lib/sgml/docbook/print/docbook.dsl" CDATA dsssl>
]]>
]>
<style-sheet>

then further down:

(define %graphic-extensions% 
  ;; List of graphic filename extensions
  '("eps" "pdf" "gif" "png"))


<![%output.print.pdf;[

(define %graphic-default-extension% "pdf") ;;; just change this to png

]]>


<![%output.print.eps;[

(define %graphic-default-extension% "eps")

]]>

<![%print;[

;; customize the print stylesheet here


then invoke jade with -i output.print.eps or -i output.print.pdf
or -i html or whatever other options you like.
