[plt-scheme] set-origin and printer-dc%

Hi there,
 I am trying to plot some large images on a printer, breaking the image onto 
multiple pages. I am puzzled by the behaviour of set-origin.
 On my printer:
 (send printer-dc get-size)
 reports 576x753. I have an image that is let's say, 1152x753. If I try to 
draw it to the printer only the top half appears (as expected). But when I 
try to print the bottom by moving the dc origin:
 (send printer-dc set-origin 0 -576)
 I see that the origin has moved by much less than half. Is there more than 
one coordinate system here? what am I missing?
 Thanks in advance,
