Step 4: See if the drivers are working.
You can tell that you have the correct (Disk-printing enabled) drivers because because you should now have a new "media type" available to you in the printer preferences.
If you have this option then the drivers are working correctly so you can skip the rest of this step and continue to the next step. If you don't have this option, keep reading. You may need to change some registry keys. But don't worry, it's easy.
a. From Windows' START menu click RUN
b. Type "regedit" (without the quotes of course).
c. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Print\Printers\Canon PIXMA iPxxxx\PrinterDriverData
d. Find "CnmFSI_CDRSWITCH"
e. Right-Click and choose "Modify"
f. Change the value from 0 to 1
g. Click OK and close regedit. When CnmFSI_CDRSWITCH = 1 there will be the extra options for printing on Printable disks.
