Roberto,
I do not know if it will make you feel any better (sarcasam) but I just bought an HP B209a a few days ago and in the store there was an HP sales rep and an Apples sales rep 3 feet apart and they got arguing if the printer would work or not. The HP guy said to go on and buy it because it would work. Well, it does not obviously!!!!
Anyway, apart form all the valid concerns posted, from recycling to buy a new USD150,00 printer, the fact that 2 companies like Apple and HP come to the market with a new standard and do not clearly know what to do is very troublesome. Worst yet is that we, consumers, are paying for it.
Secondly, all this said "support" that we seem to be getting but at the end of the day the guy who is giving it (yeah, I do not particularly care for your name) is saying it cannot be done. Well, a printer is hardware and, provided that the supplier - HP and apple -are willing, any software can be installed and I am sure that ePrinter drivers could also be installed as well. If the suppliers are willing.
Finally, the HP iPrint at the Apple store is neat, but it would be even better if did not crash most of the time and actually work with other type of files other then pictures.
Oh! You all are wondering why I do not take the printer back and get my money. That is what you get when you live in developing nations like Brazil (by the way I am brazilian) where the shop where I bought it, FAST, HP and the newly stablished Apples Store are pushing to each other the blame for the wrong sale and I will be stuck with the wrong product.
So, the best thing to do is not to buy HP again.
