Workaround for HP CPU gltich on 10.2.2 System
I have an HP-PhotoSmart printer (but this problem affects several HP models) running 10.2.2. Every time I went to use my computer after a small/long absence, I noticed my mouse was, for lack of a better word, "wispy". When doing a "top -u" in terminal.app, the process "kernel_task" was hogging CPU even on my dual box.

At first I thought it was the screen saver going foobar, so I changed it then completely turned it off. I tried using "ktrace" but this doesn't work with the kernel (can anyone tell me how to "debug" or "trace" the kernel?). Finally, I googgle searched like mad and found this tech note from HP. I also ran across a program called "DealWithHP" which solved it for me; I found the reference and more information on macfixit.com. Here's the original story.

Alternate Work Around for Photosmart Glitch
Authored by: ThatWebGuy on Dec 09, '02 10:28:27AM
Actually, I gave up and took a simple approach that has allowed me to print to my Photosmart 1215 without any problems. I went back to an earlier printer driver that seems to work just fine in Jaguar.

I can't recall where I found the driver (you can't get it from HP). Therefore, I have uploaded the driver and it is available at the following address:

Another solution from Apple

I like the HP blank wall with "did this help?" And a 404 from macfixit? Well I don't get anything from those links (browser problem?) but try this thread on the forums http://forums.macosxhints.com/showthread.php?s=&threadid=7179 I went thru hell to get it right. But the system is working well now and the printer works too! Caution Terminal required!
