I'm trying to set up new MacBooks and encountering several problems, the most annoying is the fact that older HP printers can't be added.

yeah... I read that and Creative Suite 2 does not work at all! Older HP printers always are a problem when Mac updates OS... HP never

puts out new drivers...

No, I bought 5 new iMacs for the YB teacher. She's gonna be angry... We use HP exclusively, so that is a major problem. Pain in my rear..
