Using XP, my HP Deskjet 5550 printer allowed me to

Using XP, my HP Deskjet 5550 printer allowed me to set margins of 0.5 inches and the document printed correctly. With my new Vista 64-bit OS, I get a message that the margins are outside the printable area of the page. If I ignore the warning and print the document, the type at the 0.5 margins does not print. If I "fix" the problem, I am stuck with a 0.6 bottom margin, and my text reflows. Is there a solution, other than buying a new printer?
