sorry.. i dont own a canon printer but im using epson t50 to print cd/dvds.
so far i found that verbatim's printable cd/dvds are slightly better. the surface feems slightly smoother. Imation isnt so bad either.. dont get those no brands. and if you do stick the laber onto the cd, some dvdrw/cdrw cant read it or simply cant insert it into th cd tray because of the thickness ie : slot load like macbook/lenovo y series etc
