It's a CD burner. My presumption (although I haven't tried it) is that if you put a DVD-R into the machine, it will ignore it. At least that's what my CD burner does with DVD-R blanks.
The concept with CD blanks is that the burner can "spell" out text in the unburned outer portion of a CDR. The catch is that it does it in the unburned portion of the CDR. In other words, to use that feature you will lose capacity.
My gut feel, for what it's worth, is that over the next year or two the inkjet printer vendors will begin mass-marketing printers that come with an "adapter plate" that can hold a white-coated CD or DVD as it passes through the machine. Right now you can buy such a machine, but it's $500. Assuming the printer uses smear-proof pigment inks (like Epson), this will solve the label vs. felt pen issue.
The largest duplication facility in Western Canada uses custom made PRINTABLE labels on duplicate DVD-Rs. Not sure what the label is made of but they are sending us a couple of sheets to try. They have not had any dud DVD-Rs returned. I believe they are using Maxell DVD-R blanks (5.00 CAD), not the $.66@ type.
I don't like to adverstise in these forums, but since the topic is up my company makes a printer called the Everest that does silk screen quality print on just about any kind of media (DVD, CD, different sizes, etc.) We also have a lower cost thermal printer call the Prism that does simple color. This labeling is completely secure and will only come off if you scratch it off the media.
phew, $2795 converted to Canadian dollars is out of my league at the moment. Guess I'll have to hope the dupe house's printed labels work. However, if I can ever build DVD duplication into a serious business, that press is exactly what i'd like to have.
Anybody need to know what horses are going to win at the track this weekend?
As an aside, our home now has three inkjet printers--an Epson C80, an HP 700, and a Canon F30. The Epson and Canon have separate ink tanks, which is nice. My favorite is the Epson, which uses permanent "pigment" inks. They won't rub or wash off, and they supposedly won't fade like conventional inkjet inks.
A few years back I had a job which entailed calling on both the laser and inkjet-printer divisions of HP. Seems they had some friendly wagers going among themselves on which color printing technology was eventually going to dominate the market. At this point, it looks to me like inkjet is gradually pulling ahead.
