Digital BW, The Print

I am printing with a 1160 and cone's piezography driver. All of a 
sudden the images are not centered on the paper. I have made the canvas 
the same size as the paper and they are sill not correct. I have check 
the center option with no luck.

I am sure this is not a big deal, I must just be over looking 
something.

Thanks for your help.
