I need to be able to print to my Canon MP530 printer from my Ubuntu 9.04 powered PC. The printer is connected via USB to our iMac. The iMac and PC are hard-wire connected together via our Seimen's Speedstream modem/router.

I've been able to use the printer very well when the PC was operating under Windows Vista using Apple's Bonjour for Windows utility (and intermittently using the same utility with Windows 7 RC). But when I tried to use the CUPS utilities to set up the printer so it would work with Ubuntu everything seems to go very well until the end. That's when I get a message which says, "Missing Driver: Printer 'mp530' requires the '/System/Library/Printers/Libraries/PrintJobMgr/Contents/MacOS/PrintJobMgr' program but it is not currently installed. Please install it before using this printer."

Where can I obtain a MacOS PrintJobMgr driver and how do I install it?

Never mind. The printer works fine under my configuration. No need to find and install any other driver. The error message is a fib designed to fool fools like me.
