The 
simple-print-port
 function prints the output pane specified by 
port
 to the default printer, unless specified otherwise by 
printer
. The arguments of 
scale
 and 
dpi
 are used to determine how to transform the output pane's coordinate space to physical units. Their meaning here is the same as in get-page-area, except that 
scale
 may also take the value 
:scale-to-fit
, in which case the pane is printed as large as possible on a single sheet.
The background color of the pane is ignored, and the value given by 
background
 is used instead. This defaults to 
:white
.
If 
interactive
 is 
t
, a print dialog is displayed. This is the default. If 
interactive
 is 
nil
, then the document is printed to the current printer without prompting the user.
