Ok, I'm not exactly sure where to post this, it could go under Mac OSX, Peripherals, and under the macbook sign... so if someone disagrees, sorry.
But alright, my mom and I both have macbooks. I've had mine for a year set up with out Canon printer at home to print wired and wirelessly over airport. My mom got her macbook about a month ago, and I set her up to print wired/wirelessly as well.
I live at college now, and coincidentally have the same exact printer in my dorm room that she uses at home. She called me all last week complaining that her macbook fans were running at full blast all of the time, and after she took it to the Apple store, they gave her a brand new battery to try and solve the heat issue.
Well I got home yesterday for thanksgiving break, and tried printing on the Canon (same model I have at school). For some reason, the airport won't recognize the printer wirelessly anymore, on either of our computers, so we have to print wired.
This is kind of a complicated issue so sorry if it's not making much sense: but after we print wired (from either of our macbooks) our fans start revving at 100%. After a quick google search, I opened up activity monitor and found that a process called "PrintJobMgr" was taking up 100% of the CPU. That is what's making the fans whirl constantly, and I have to go into activity monitor and force quit the process to turn off the fans.
So what's going on here? This is a repeatable issue on both my mom's and my macbooks, but sometimes it stays in activity monitor for just a minute then leaves, and others it will stay until you force quit it, meaning your fans are running and your computer is burning your legs until you quit it.
Anybody have any clue what to do? It seems like it's a Canon-related issue, but the google search I found had someone using a Canon and 10.3 and this exact problem was happening. And why won't this printer show up under the Airport menu when it did just under a month ago? I am completely baffled by this whole situation.
Thanks so much for your help guys, it's really appreciated.

Yup.
It seems to happen every time I print, but then it goes away if the print was successful. If the print fails, however, it stays running in the background then heats up your macbook and blares the fans until you manually quit it from activity monitor.
I'm sure it's no use calling Apple, cause they'll blame Canon and you know Canon will blame Apple.

Did the problem occur coincident to anything else? 10.4.11 update, Leopard install, anything?

I thought it was Leopard, but my mom said she's been having this problem since about a week after she got her computer (right when she got the printer...) It seems to be OS irrelevant, as when I searched on google, the post that gave me the tip to check Activity Monitor was someone using 10.3 and it was from like a year or two ago. But they did mention it was a Canon printer as well.
