I have just purchased the Canon IP4200 (excellent printer) that definitely does print straight onto CD's and DVD's. Unfortunately I too am unable to use label creator as it only comes pre-loaded with Epsom printers. I have tried all of them and none print the image in the correct place for the Canon. I have had to resort to the Canon provided software which is vastly inferior to EMC.
Does anyone know how to configure EMC to use with a Canon IP4200 - if not, come on Roxio, support more printers!
