Narrative:

Air carrier X en route at FL320. I offered a short cut direct pke VORTAC. The pilot asked; 'what do you want us to do after pke?' according to pilot; pke was not on his flight plan. After further investigation; pilot thought his flight plan was: ...KA27S..drk..eed..ubabe.SBONO1.psp; flight plan in the host system was: ...payso..drk.J96.pke..ubabe.SBONO1.psp. As an en route controller; I don't completely understand how clearances are issued on the ground at major airports. But from what I understand; some of these clearances come out of a printer and are not verified verbally/completely from controller to pilot. If this is true; obviously there is a margin for error here; which is not good. If the pilot is flying one route and the computer thinks he is flying a different route; the possibility for operational errors; airspace violations increases.
