Narrative:
I received the VFR flight strip for the PA28 indicating he was flying eastbound at 2500 ft. He was told to proceed on course VFR, but wanted to go northbound. When he turned north on course, he became a conflict with the B737 who had departed behind him. Clearance delivery had thought the PA28 said he wanted to go eastbound, but he said northbound.
