I don't see how this pertains to PS. This simply sounds like you never bothered to actually calibrate the printer and its paper transport system therefore operates on wrong assumptions. That or its mechanical systems are damaged. So perhaps spending some time in the driver and the tools that came with the printer might do wonders. For anything beyond that you would have to provide proper system information and details about the printer, anyway, which you haven't doen so far.
Wow. In other words, I'm useless bag of skin. Thanks
