I had a similar problem when, after replacing my Epson 740 with a Canon iP 6700D, found it would not work with Classic. Got round it by making a PDF of the document from the Classic program (in my case QXP 4.1) which can then be printed from Adobe Reader (in 10.4.11 at any rate).
Might be worth looking into if you don't do too many documents in Classic.
