Printing and previewing

i created 2 teststacks, modified your script a little bit for these  
stacks and ended
with a nice, correct yet invisible screenshot of the "printstack"s  
content!

on mouseUp
   put the loc of stack "printstack" into altloc
   set the left of stack "printstack" to 2500  --off screen
   put the windowid of stack "PrintStack" into tWinID
   put "0,0,"& the width of stack "printstack" & comma & the height  
of stack "printstack" into trect
   set the rect of the templateimage to trect
   create invisible image imgname
   export snapshot from rect trect of window tWinID to pictvar as JPEG
   put pictvar into image imgname of this stack
   SHOW img imgname of this stack
   ## optional, but looks better ;-)
   set the loc of stack "printstack" to altloc
end mouseUp

Did I miss something?
