Is HP OfficeJet Pro7740 Laser or InkJet?

UPDATE: I checked the required cartridges and they are definitely InkJet! Shame. I'm looking for a Laser Printer that can use 11 x 17" paper.

On the Apple Store under Printer Technology this printer is listed as Laser, yet HP website says HP Thermal InkJet. Can someone who has this printer clarify this for me? I would wait for responses from both Apple and HP, but someone in the Apple Community might know and respond faster.

Thank you
