So this printjobmgr process was using 50%-90% of cpu! No wonder my fan kept kicking on! I restart thinking that would stop it, but nope. Upon restart it started to print out something I had printed last night but only printed it a bit of the way. I cancelled that from the printer. Then I force quit printjobmgr from Activity Monitor. So was that okay and why was it doing that to begin with?

Wow, almost 3 years later and this issue is still here.

Only happens when print wirelessly through APE/Canon MP530, but it sucks because I want to print wirelessly, not have to get the cord each time (or have my fans running at full blast 24/7). Can't believe they haven't fixed this in 3 years.

Could be completely unrelated.

It could be.

I searched through google for something like "canon mp530 printjobmgr" and this thread was one of the results...

Even if it's completely unrelated, the fact is that it's only the causes that may be unrelated - the problem is still exactly the same. Printjobmgr running at 100% of CPU, making fans run at full speed and the computer get terribly hot/loud, and the only way to end it is to force quit via activity monitor.

So no, it seems like it's a persistent issue regardless of the cause. (And it happens on both mine, my sisters, and my moms macbooks back at home with that printer, so it's not just a single-computer error, it's something wrong with the underlying system).

I am seeing PrintJobMgr run away ant eat all CPU each time something out of the line (paper jam, lack of paper, lack of ink) happens when printing to my Canon i560.

This happened when printing to the Canon i560 which was shared by another machine. It happens now that the Canon i560 is attached to my AirPort Extreme.

Been like this for years!

Yup. After searching through google, it seems like it's mainly a problem with various canons and airport extremes. And the earliest report was from 2004. This needs a fix!
