What's the deal on these? How does one print onto the DVD disc itself
There are presently three forms of consumer disc printing i'm aware of
1. Inkjet
Basicly offering a stright path and a disc tray the printer prints
directly to a disc. This is an option with Epson printers, the r200,
r300, and r800. Canon printers in the US don't officaly support this
feature, but most of the market outside north america does. This
feature can be enabled in Canon printers if you so desire, a tray can
be made from cardboard, or an epson tray, or you can order one. The
ip3000/4000/5000/6000/8500 and mp750/760/780 support this feature and
can be enabled in the US. The newer printers like the ip4200/5200/6600
and mp800 look like they do as well but no one I know of has tested it.
Ebay is presently the only known resource for canon trays, expect to
spend $30ish on one.

Partsnow did carry the tray for $15ish shipped, but no longer have the
part in stock.
2. Thermal ribbon
Casio and Primera offer dedicated cd printers that employ the use of a
thermal ribbon. Such printers are usually limited to one color at a
given time, and the ribbons tend to cost more than inkjet ink. But
unlike inkjet they are waterproof and don't nessicarly require special
discs to print on.
3. Lightscribe
These are discs that on the label side have light senative media that
permits a properly equiped dvd drive to etch a monochrome image. This
process is slow, the discs are more spendy, but totally water and rub
proof.
What you are looking at at costco are inkjet printable. These TDKs are
costco are not hub printable, as in you can't print to the center hole.
The DVD-R, the ones marked made in Taiwan/Japan are reported as being
good. The printable part of the disc is excelent.
