I've never had a problem just printing the pass part, though I generally use their app now. Some trivia: Ryanair are not IATA members but discovered that organization had issued them a code of FR, for internal use. Ryanair just started using it on boarding passes and flight information systems and save themselves thousands in IATA membership fees! Easyjet aren't members either but instead use their catchy ICAO code EZY. Their philosophy being that if an airport wants their custom they can damn well upgrade their system to handle three-character codes.
