A320 CREW HAD TRACK DEV DEPARTING RWY 22R AT BOS.

Narrative

WE RECEIVED OUR CLRNC VIA ACARS; BOTH PLTS REVIEWED THE CLRNC AND AGREED THERE WAS NO DEP SID; MOST PROBABLY DUE TO RWY AND DIRECTION OF FLT. SITTING #3 FOR DEP ON RWY 22R BOS; THE OTHER ACFT WERE GETTING HEADINGS AS THEY DEPARTED AND I ADVISED THE FO (PF) WE WOULD PROBABLY GET A HARD L TURN AFTER TKOF. WE WERE NOW CLRED FOR TKOF; THE TWR FREQ WAS BUSY DUE TO OTHER RWY TFC AND TFC HOLDING SHORT ARE RWY; NO HEADING GIVEN. AFTER AIRBORNE TWR ADVISED; 'CONTACT DEP' (STILL NO HEADING). I CONTACTED DEP AND SHORTLY THEREAFTER THEY ASKED OUR HEADING. I ADVISED RWY HEADING AND THEY ASKED WHAT HEADING TWR ASSIGNED; I ADVISED NONE. WE WERE THEN GIVEN A 090 DEG HDG AND A SHORT DISCUSSION ABOUT THE LOGAN TWO SID. AT THIS TIME I REVIEWED THE PRINTED ACARS CLRNC AGAIN AND FOUND THE LINE I HAD MISSED BEFORE LOGAN 2 DEP. CORRECTIVE ACTION. HOW COULD BOTH PLTS MISS THE SAME LINE ON THE ACARS PRINTOUT OF THE CLRNC? SOME SUGGESTION FOR THE PRINTOUT; PUT IT IN CHRONICLE ORDER. PUSH AND TAXI INFO ON TOP THEN DEP INFO; THEN ENRTE INFO; ETC. DON'T PUT CAF; (CLRED AS FILED) WITHOUT INSERTING THE SID. THINKING BACK TO OTHER BOS DEPS THE TWR ALWAYS GAVE US THE SID HEADING WHEN TAKING OFF AND USUALLY AGAIN WHEN CHANGING TO DEP. I DON'T KNOW WHY WE DIDN'T GET THAT INFO THIS TIME BUT IT WOULD HAVE HELPED CATCH OUR ERROR.
