As a cheaper alternative, Is the Casio CW-50, which is about the size of a large cigar box and does nothing but print labels directly onto CDs. It doesn't require special surfaces to print; in fact, bits of the type will get left off if it's fed anything but perfectly smooth CDs.

The CW-50 has a list price of $110, but it sells for about $80 online.

If you don't need to print on CDs, consider an all-in-one printer. I looked at the Lexmark X215, a $499 all-in-one laser printer with scanning, faxing, copying and black-and-white printing capabilities.
