I noticed that no one in this ip4200 thread has mentioned going to:

"Five Easy Steps to enable the Canon USA models to print directly to
CD or DVD"

I followed the steps to reprogram the ip4200 and made my own CD/DVD
template last year. After printing over 100 full-face DVD labels,
the printer and homemade CD/DVD tray still work perfectly!
Although the center hub seems more precise, using a CD as a cutting
template for the top layer CD "well" results in a tray that holds
the CD/DVD very precisely. To overcome the lack of the additonal
rollers, you only have to push the tray in an inch or two at the
beginning of the disc printing to overcome the resistance of the
printer to the front edge of the cardboard tray. The mechanism
synchronizes the tray position to the three mirrored squares. After
slight calibration adjustment (Acoustica CD/DVD print program), the
printed label alignment is dead-on accurate.
BTW, I bought a used Epson R300 last month to compare the DVD
printing quality to the ip4200 (the R300 sits fine on top of the
Canon printer!).
The conclusion: although both printers can print excellent disc
labels on printable DVD media, the Canon-printed disc prints dry and
is available for immediate use. The Epson-printed disc has to sit
for a few minutes to dry sufficiently for handling.
I like Epson (I still have my Stylus 500, Photo 700, C68, and C88),
but I have to say, with the Canon I have NEVER had to initiate a
head-cleaning cycle, and the printing quality (paper and disc) has
never been short of excellent.
I bought the ip4200 with a PowerShot A410 camera at Staples for $99.
Although I bought the printer for it's disc-printing capability
(after resetting the firmware), I have found myself using it for
it's reliable standard printing several times when the Epson printer
sitting on top of it has "gone bonkers."
And, of course, the Epsons can't print automatically in duplex mode.
Sorry for digressing!
From what I understand, Canon agreed with (or was coerced by) Epson
for Epson to offer the only printers sold in the United States to
have direct CD/DVD printing capability.
I can see why, based on the quality of the disc printing using the
Canon ip4200.
