I am using a Vista ultimate desktop with HP Deskjet 5550 with Duplexer. I was using this successfully with Windows XP, but having some problems since i upgraded my system to Windows Vista. I installed the printer, installed HPA drivers and even enabled duplexer in the driver, and then select 'double sided' in the finishing properties.
All ok but when i try printing more than 1 page at a time (no matter from whichever application) the first page prints fine but get stuck on the second page. During the second page it sticks into the duplexer, spins it around, then spits it back out the print the other side and the second print gets out upside down! I never had this problem with Windows XP. Is it driver problem? I guess its Vista drivers unable to rotate the page correctly, and as
a result it makes a mess of the print. Any help will be appreciated.
