When I was out in June I had hand luggage only, it said specifically on my EJ itinerary that Dalaman did not support online check in so I queued up, some people went straight to the gate with home printed boarding passes and the EJ staff at the gate were calling out names and handing out the Dalaman issued passes. This time they accepted the online self printed ones so I would interpret that as they have changed their system so you should be safe to go to the gate.
