If you live in North America, to print on ink-jet disks, I can recommend the Epson printers - although careful study of 'what's available' will tell you Epsons are about it! If you're in Europe, there are Canons and Epsons that are roughly equivalent.
In North America, I enjoy the Epson Artisan 700 series - which are now replaced by the new Expression Premium 600 and 800 series.
I can still find Epson Artisan 700s from the Epson Store as Refurb Units, often in the $70-90 range. At this price, buy two because they each contain $70 worth of ink, and IF you get a bad refurb unit, you've got a replacement immediately! Very handy.
The Artisan 800 series is the same unit except with an auto-sheet-feeder attached on top. If you do a lot of page scanning, then perhaps this is useful. It's not to me so I avoid the 8's.
The new Expression Premium 600s and 800s have direct-on-disk printing - the lower-numbered unit (400s? 300s?) don't, so be careful when you're shopping. Every few months, the Expression Prem 600s will be on sale for $99 - and normally are $30-50 more.
The Artisans have an "escalator feed-tray" for direct on disk printing. While this felt flimsy at first, after thousands and thousands of print-jobs, they are wonderfully durable and incredibly precise.
The new Expression series returns to a manually-fed 'tray' and, while we used the original R and RX series, the tray-feed rollers are "the first thing to go" - where the rollers eventually became too slicked-up to feed a slick plastic tray for accurate printing. That will take a couple of thousand feeds, maybe twice that many, but that's usually 'the death' of tray-feeders.
The Artisan is a LARGE printer, to warn you. It will take a 2-foot-square amount of desk space. Large! The Expressions are almost as wide but a few inches shallower, so they fit more easily.
