I use the HP LaserJetP1102w, Its larger than the Canon Printer but it works.
This may work with your canon printer. I google airprint printers and found this link.
Perhaps "Printopia" can resolve this issue. It's a piece of software that resides on the Mac (PC?) and allows iPads to print to non-airprint printers.
You can also send the reports as PDF's from the iPad using mail.
