I am seeing exactly the same thing. Printtool runs and slowly seems to use up all available RAM - a real leak if I have ever seen one. As you said, killing it releases some RAM but it grows back pretty rapidly. Hope this is something Apple fixes.

I seem to be having the same issue. Printtool grew to over 4GB in size before I killed its process. I noticed it emediately began to re-run in Activity Monitor at a pace of .5MB/Min. This is rediculous. It seems to be associated with PrintCore and its Parent process is launchd. I would like help, if possible, to stop.remove this memory leak.

Yes, definitely memory leak in printtool process in Lion.
My Wired memory (real mem fixed) increases with the size of the printtool process, even when I am doind absolutely nothing. After few days system is horribly slow.
Apple please solve this...

I'm having the exact same issue as everyone else. After being away from the office for nearly a week due to the holiday, when I logged in to my Mac Mini (w/8GB total system memory), I noticed that I had less than 1GB free while running no applications whatsoever! Ridiculous! So I launched Activity Monitor and noticed that the "printtool" process was hogging 2.4GB of system memory. When I killed the printtool process it relaunches using 2.5MB, but then steadily increases at a rate of about 0.5MB per minute. This is a very serious memory leak and Apple needs to get this fixed ASAP.

Same thing going on here. Have an iMac 27" with Lion (10.7.2). Looking at the Activity Monitor, it would appear that printtool is using 1.01 GB of Real Mem and 1.05 GB of Virtual Mem. Note to Apple... Please fix.

I reported in September (reported at Apple as a bug) and it is almost Februrary and I never got a response from them nor has this been cleared up. You would think as a developer they would respond, hmm.

Yes and the more people that report it means there are more votes that this is a problem needing attention. It also gives developers more eyes on the problem.
A single report can get lost if your a developer "Up to your A** in Alligators". Lots of reports makes your Alligator a lot bigger and more noticeable.

+1 for me, exactely the same symptoms.
Activity Monitor shows that printtool is taking 50% of CPU all the time, iMac 24' early 2009, newly updated to latest version of Lion (from latest before of course) last week (early Feb 2012 update).
Killing process makes it relaunch seconds after, memory occupation growing until the iMac is ULTRA SLOW.... Like it takes secondssss just to see launchpad or close program or change from one window to another.
