my i550 is no CPU hog anymore 
- Version: updates, 8/24/2008 01:42PM PST
wouter_greetje_dotmac
Before this update my i550 (even when not pluged in) took up to 90% op my CPU usage, without using anything. After this update, the i550 doesn't even show up in activity window (as it should be because the printer is not in use.) So no more fans at more than 6000 rpm, battery life back at almost 4 hour and no overheated CPU (before at or over 70°C, now 50°C)
Excesive processor use under Tiger - Version: updates, 11/9/2005 09:35PM PST

At least some Canon printer drivers are serious processor hogs when used with Tiger.
Users of i560s, i960's and some ip4000's have reported on the Apple discussions boards that the drivers for these printers consume all available processor capacity when printing. This can be checked using Activity Monitor. Look for the %CPU utilised PrintJob Mgr in the Activity Monitor window set to show "Active Processes" while printing.
I have discussed this matter with various other Level 4 members of the Apple discussion boards, who report the same effects.
The latest Canon drivers (as of 11th November, 2005) for the i560 (my own printer) do nothing to overcome the problem. It is common to see a print job take up 85% of processor capacity on my imac G5 2 GHz. Printing causes an immediate CPU temperature rise of 10 to 15 degrees Celsius. This can., on occasion, bring an iMac G5 CPU up to very close to its maximum rated temperature and can cause slowdowns in other programs.
Some users have reported that if a print job is "hung up" in the background when printing to one of these printers, the issue can persist. until the print job is removed. Resolving this issue has fixed their overheating problems with imac G5's, resulting in a general operating temperature drop of several degrees.
Later printers (such as the ip4000R and ip4200 series do not seem to be affected. Some earlier ones may be, however.
These are generally excellent printers, but clearly need drivers revised for proper compatability with Tiger.

i950 installer crashes under 10.3.2 - Version: updates, 2/24/2004 05:15PM PST
Kee Hinckley
Looks like a Java incompatibility. On top of that I can't print to a remote i950 printer (even though I shouldn't need to install anything on my machine). That crashes the application I'm printing from.
