Hi Fellow MACers, so here's the latest as of 10/31/2011. I just purchased a MacBookPro O/S Lion and tried to add it to a small business network running Windows XP and an HP 1200n BusinessJet. After 4 or 5 hours on the phone with MyApple Support and the HP Business Support, the most recent HP printer drivers update for LION will not work for any HP printer with a model number lower than 2500. HP will no longer support any of their printers with a model number smaller than 2500 for LION. So, if HP decided not to support my small business, then I have decided not to support HP. I just purchased a new Brother MFC-J6710DW and tossed my HP in the garbage. The Brother is wireless and operates on both Windows XP and Lion O/S with full support for both systems. HP has made some poor business decisions. Maybe Meg Whitman can help fix things there. Sadly, it"s too late for me. I'm a Brother customer now.
