Revived old post, but Newer answer: Use the URL above and substitute the AL-2050CS driver for your AL-1655CS. This compatible driver works great on Win 7 64 bit, including duplex option! Note: I'm network printing, so you may need to play with the port manually.
Took me a couple years of work around to spend the couple hours of trying substitute drivers. Hope this helps someone.
