It's not AirPrint enabled (those that are are listed on this page).
HP's ePrint app says that is supports their :
HP Officejet 4500 All-in-One Printer Series (G510)
HP Photosmart C4500 All-in-One Printer Serie
Otherwise there are third-party printer apps in the store such as Print Central For iPad and Print n Share which might work with it.
