I've noticed a trend recently where I'm having to clear iPrint jobs/shutdown/start printers, and what's usually at the top of the queue (status: 'Processing') is a job with a Google maps URL.

Nothing I do at the printer changes the situation. It doesn't appear to be receiving jobs.

Has anyone else experienced similar problems?

(Printer is a Canon ir3235 copier, clients are Windows 7 with PCL6 x64 drivers)
I'm looking into alt. drivers or to see if it's browser-specific at the moment...
