When I print to either a Samsung CLP-500 or HP Laserjet 2550 my documents do not print central to the page. If I use my HP Desject 960c or 1220c they print prefectly. I have tried printing Word, PDF and Omnigraffle documents with the same results. I am at a total lost as to why this happens, can anyone help? I have the same problem wether printing from my PowerMac or iBook running OSX.3.5. Any help would be great. Thanks.
