I've been trying to print from my HP PSC 750 but i've been having a port problem. Okay, my real problem is not on OS X, but on VIRTUAL PC FOR MAC v.6.0, and i'm running Windows 2000 Pro, when i try to print, i always get a message saying that a problem occurred while connecting to port dot_004 .... anyway, i've been trying to fix it, but no success until now !
