Finding an inexpensive CD printer can be problematic.  Epson makes some caddy based all in one devices which contain a scanner and inkjet printer or just the inkjet printer alone. Epson seems to keep discontinuing the models so it's a bit difficult to speak of a specific models performance.   Caddies are a plastic template that holds a CD or DVD and moves through the printer feeder like an envelope with the disc held in place as the ink jet print head passes over the inkjet printable disc.  

Two entry level CD/DVD printers available in the marketplace are the DYMO DiscPainter and the CD Dimensions DISCPRINTER thermal disc printer. The two represent different printer technologies available today. the Dymo relies on ink jet technology and the DISCPRINTER uses thermal transfer technology. Even more unique in the case of the DiscPainter is the radial printing technology incorporated into the DYMO DiscPrinter.

Typically a CD DVD printer puts down ink in a back and forth method, starting from one end of the disc to the other. Radial printing starts in the center and works it's way out in a concentric circle. This can make printing much faster especially when the text or graphics is around the hub area. There is always a trade-off and in the case of the DiscPainter it has a lower resolution then a standard CD printer. Almost all inkjet CD printer units are 4800dpi vs. the DiscPainter which prints at 1200dpi.

The DISCPRINTER thermal printer by CD Dimensions (and very similar to the Teac P-11 and the now discontinued Primera z1 printer, Primera part number 56300). The only difference is the price. The DISCPRINTER by CD Dimensions uses zone printing. That is it prints in 4 rectangular zones only. For simple disc labeling this is all you really need. Unlike the DYMO DiscPainter and other ink jet printers the Teac P-11 & CD Dimensions DISCPRINTER can only print in single colors: Black, Red, Blue and Green. However it does not require special inkjet printable media like the DiscPainter. Nor do the ribbons dry out like ink does.

It's important to remember that these disc printers are not production units and they do fill an important function in a occasional print job where a automated unit is not required.
