Digital BW, The Print

Does anyone on this group use a 7500 and Roy's QTR software or print 
with Gimp-Print under OS 10.2.6. I'm having a boarder problem. When I 
have the print centered in the preview it comes out of the printer 
off center. The "Top" of the print that is the part which is first 
fed into the printer is longer than the "bottom" which is the last to 
come out. Any suggestions.
