The Paris and Euro Disney train schedule, i.e the RER A train line, can be found at Paris by Train.
The RER A train travels West to East across Paris, connecting the financial district to the shopping district (Galeries Lafayette) to Gare de Lyon, to the eastern terminus of train line to Euro Disney / Marne La Vallee.
When taking the RER A to Euro Disneyland or refering to the printed schedules, remember that the direction you want is Marne La Vallee — Chessy. On some train line panels, the name Boissy–St-Leger may be shown as well.
To download a schedule of trains running from Charles de Gaulle Airport to central Paris, see the RER B Timetables article at Paris by Train.
The RER B train schedules are separated into two files by direction, southbound leaving CDG Airport would be in direction Antony, Robinson, St-Remy-les-Chevreuse. Going to CDG Airport from Paris (northbound), would be direction Mitry-Claye, Aeroport Charles de Gaulle. Be sure to download the correct schedule.
You may also want to refer to the instructions on how to read the RER train schedule sheet, which can be overwhelming at first glance.
