HP Deskjet Printer, 5 years old

I was running on 98SE and changed to XP a few months
ago.Printer was ok until just recently when the text
and/or media start to NOT print all the way to the right
side of the document. It probably cuts off about 1/4 inch
or a little less. I doubt if its' the driver because it
was ok when I started to use XP so it's only lately that
I noticed the problem. Maybe an allignment problem but if
it is I don't know how to fix it.

Does any one have any ideas that might fix this?
