Correct. When you refer to "printer" I'm assuming you're talking more high-end, and not the corner copy center.
While I've used printers that accept Corel, I still liked to export as EPS.
As mentioned, convert all text to curves. Make sure to save your converted to curves file as a new file, incase you have to make text changes later after the fact.
Also make sure all colors are CMYK, or if you have to hit a certain color, Pantone. But Pantone printing will cost you slightly more.
If you're copying your file to CD, file size really isn't an issue. But if you have to e-mail the file to the printer, EPS files can be huge. Using WinZip, zip the EPS file and you're e-mail will thank you.
