Why are you asking me this?

You have a specific question that I do not feel qualified to answer. You should post your message on one of the forums. Sorry.

Hi --
My previous printer was an HP6122, a duplex printer. It still works, but once I changed one of my Pcs to a Vista64 OS, the printer no longer would function with a laptop running XP. I went through a l-o-ng discussion with Project Leaders, etc.,with the bottom line "never the twain (Vista & XP) shall meet.
ANYway, I purchased a network ready HP6988, and Hp sent me a 'duplexer box' to do the duplex chortes. It is an HP5712A. I have it working as a duplexer after a fashion, but it did not come with a uSER'S Guide. Further discussion with HP Project Leaders confirmed that they have no resource to send me one... no source, no PDF files, nothing. Do you, --- or anyone have a 5712A duplexer that I might ask questions to?
I would appreciate help from anyone! Thanks!
