Digital BW, The Print

After reading up on quadtone inks, I decided to pick up a used 1200 
and start making B&W prints.  I am probably making a newbie mistake, 
but every print I've made so far in landscape mode is off center to 
the left by about one-half an inch, despite checking the "center 
image" box in photoshop.  I'm also noticing that the bottoms of my 
page numbers are being cut off in Word.  Did I miss a setting on the 
1200?  What am I doing wrong??!!
