I was the proud owner of a Z51 printer, I now own a HP 970 printer, I have talked to lexmark 4 times, sent 2 e-mails, and all I get is the same response, the updated driver's are not ready yet, HP had their driver's installed on the win2000 disc, and the drivers are working fine. I was a Lexmark man, but they screwed up bigtime, I can afford to go out and get another printer, but I'am aware of a lot of people who can't, and are stuck with a new O/S and no lexmark printer to work with it.Lexmark should have seen this coming, they didn't and believe me, I'm spreading the word.........
