This can happen for multiple reasons.
1. There is too much information in the file (too many nodes or anchor points).
2. The document itself has become overloaded.
3. A component of the file is corrupt.
4. The drivers for Accurip and the Epson have become corrupt.
First, try opening a new document, drawing a simple square and outputting this via your Accurip to Epson printer option. If this prints correctly, this is a sign it is the document itself causing the issue. Try one of the following-
1. Clean up any excess nodes, copy and paste the image into a new document and convert it to curves (highlight and right click the image).
2. Any traced items, try retracing.
3. Any text, try a different font or converting to a bitmap (if possible for the design).
4. Worst case scenario, you'll need to rebuild the entire image.
If the square prints out as text as well, it's the drivers. Click here for further instruction.
