Printing from ML to SL

For a few months when printing from my MacBook to my mini running SL it's been cutting off the bottom of the page. Wasn't a big deal, but now I need it to work. Checked the page and printer settings without luck. If I print the same file from the mini itself it works perfectly. Only thought I have is its an issue with printing from 64 bit to 32 bit? Any thoughts? It's a canon mp480 printer if that helps. Thanks in advance for your help.
