Error message: "document may contain binary EPS file which can cause print failure"

Question

Can anyone help me with this error message?  I have an .indd file that contains about 20 logos and various images.  I was under the impression that using eps / ai / and psd file formats for printing was best in InDesign.  (It is a 25 page document).  When I try to print the document i get the error message that says:
"This document may contain binary EPS files which can caise the print job to fail.  If the printer produces output then the binary datat did not interfere with printing. Do you want to print this document?"
Well - my document did not print for me .. so hwo can I fix this?
Thank you,

There are many ways to fix this.
Re-saving EPS files as AI is fine.
Re-saving EPS files as PSD is a bad plan -- EPS files are vector graphics, and PSD typically aren't. Also, AI files are PDF files that are generally readable by many applications. PSD files, not so much, (though InDesign certainly can).
(You could also re-save as an EPS file without 8-bit/binary data.)
What does the error message mean? Well, EPS files are a type of PostScript file, and PostScript has many ways to store image data. It can be stored as 8-bit data, which is the most space-efficient. It can also be stored as base64 ascii, i.e. just letters and numbers and soforth, which takes up more space (I want to say 130% more?).
Depending on exactly how your computer is connected to your printer, those 8-bit characters can cause problems and may not make it all the way to the printer. If that happens, then you get this problem. The warning message is there to let you know that if you have a non-8-bit-clean printing path, then you may have a problem.
