Hello. I have the MBP, PC, iPod Touch and the iPad 2. I am considering to buy a wireless all in one printer from HP or Epson. As you know, each company has their own implementations: HP has: ePrint, ePrintCenter, Print apps Epson has: iPrint, AirPrint, Epson Connect Email Print and Google Cloud Print. Which company has better implementations? Do they function equally well in a multi OS environment?
