Primera Technology has released a low-cost thermal CD/DVD printer which prints directly on CDs and DVDs, has an USB interface, and can print text and graphics. The Signature Z1 CD/DVD Printer prints onto the surface of your discs with a tough, waterproof, thermal transfer ink (ribbons are available in black or several other optional colors). This is a handy printer great for labeling your backups or home movies and at $139, it’s the only economical choice I’ve see so far.
