I am using the most recent version of Illustrator on a Macbook Air. I am unable to save ANY files as EPS, getting an error message each time. Doen't matter if I create a new file from scratch or open an existing file, make a change and "save as" or even simply resave. Each time I get the error message "Can't save the illustration. Can't print the illustration."
I tried a complete uninstall and then downloaded the latest version and reinstalled. Same result. I don't have the same problem on my office Mac Mini running the same software.
Sorry to hear about your experience. In addition to Larry's question, would you mind sharing the exact version of the app & OS? Are you trying to save it on a local drive or on a network drive?
You may also try resetting Illustrator preferences once by following steps below:
Close all Adobe applications.
Go to locations
Rename Adobe Illustrator, com.adobe.illustrator and Adobe Illustrator 24 Settings folders to Adobe Illustrator.old, com.adobe.illustrator.old and Adobe Illustrator 24 Settings.old
Launch Illustrator from the Creative Cloud.
**Please note that resetting preferences will remove all the custom settings and Illustrator will launch with default settings. This way all your old settings will be saved in .old folders and Illustrator will recreate new folders with default settings.
Let us know how it goes. Looking forward to your response.
