Unfortunately, the iPhone does not have a native option for bluetooth printing.
The only printing options available for the iPhone are AirPrint (built directly into the OS of the phone), which allows you print to AirPrint supported printers over a wireless connection.
The other option is the ePrint Home & Biz app, which also works over a wireless connection, unless you have ePrint set up on the printer. If you have ePrint set up on the printer you can add the email address into the app to print over you wireless cellular signal.
The bad news is, neither of those options are available for your printer.
Here is a list of supported printers for both AirPrint and the ePrint Home & Biz app.
