After engine start; the aircraft flight deck filled with smoke. The pilots ran the appropriate originating and before start checklists at the gate. The paperwork was handed out and the main cabin door and flight deck door were closed. The before start check was finished below the line. Engine 2 was cleared and started successfully. The First Officer waited for 75% NH on engine 2 then began to slowly turn on the bleeds. Engine 1 was cleared and started successfully. The Captain called 'good start' after the starter disengaged. The First Officer then turned on bleed 1. Three to five seconds later the First Officer noted smoke coming from the Captain's gasper vent. The Captain called 'smoke;' and shut down engines 1 and 2 using the memory action items. The flight deck door was opened and the Captain commanded the flight attendants to evacuate the aircraft due to smoke in the flight deck. The Captain then quickly notified Operations; saying 'smoke in the flight deck; we are evacuating onto the ramp' and then immediately shutting down the batteries. The Captain then exited the main cabin door and directed the passengers away from the aircraft; under a covered walkway. Once the passengers were safely off the aircraft; the Captain notified dispatch of the situation and requested fire rescue to check the airplane for hot spots or fire. No injuries occurred.
