InDesign- Adobe Print Engine has failed

[CynP]

I have the same problem as someone before but not see the solution... I am getting a message when trying to print: InDesign message is "The Adobe Pirnt Engine has failed to output your data due to an unknown problem." Execl: "Microsoft Excel could not communicate with printer" with a bunch of possibles, non help. And, Entourage: "Not enough memory".

I have done everything I can think of....help.
