Hi, Can anyone tell me if TK represented at the Airside Star Alliance "Transfer Desk" at Frankfurt Airport upstairs near the B-Gates?

I am on a trip that starts at YVR-FRA on LH, and connects to the next flight as LH (at FRA), and finally followed by a 3rd segment which is on TK (all on same ticket). In the event that I can't get the TK boarding pass issued by LH at YVR checkin, I am hoping to get it at FRA airport before my next connection so that I don't have to go landside. TK website shows that I cannot issue an online boarding pass for the departure airport where I am flying out with TK. Thanks!
