I, too, was unable to find Linux drivers for the Canon MP530 and have since discovered that there are none. My solution was to attach the MP530 to a Windows XP machine and used Samba. I did, have some difficulty in activating all of the MP530's features.
There is, however, a cost-based solution called TurboPrint. Use the following URL to access the TurboPrint homepage:

Send me you email address and I will keep you posted regarding my continuing research efforts.
