The LR3 error I was getting was “?:0:Attempt to Compare number string” and could no longer access the Develop module. Deleting the Preferences file fixed it!! The step by step instructions here are GREAT! Thank you!!

The tip to find the preference file, since it is hidden in windows, was priceless.
Thanks

Thx Rob for replying to me. I tried both and no luck. It prints fine from CS3 so it is LR 2.7. Any other suggestions would be welcomed. It’s almost like it’s stuck on a setting some place. I’m on SP 2. Is it possible that I need to upgrade to SP3 in order for it to work properly?

Well, it won’t hurt and it is free, but in my experience, most printer related problems boil down to the printer driver. Replacing the preferences is a good first step and fixes a lot of odd problems. If it doesn’t solve the problem in this case the next thing I would do is uninstall/reinstall the latest printer driver.

Before I go in and start playing around, I need to know if this will help me with my problem. I just recently upgraded to LR 2.7 from 2.6. All was working fine in 2.6. Now the only image that prints out correctly is one that is set to print at 8×10. If I select 11×14 as my cell size to print, the image prints at 7×9. Same if I select 4×6. Something is stuck some where but as I said would like to know if messing with my preference file will help me>

This tip really saved my bacon. A power failure corrupted my LR catalog location, and deleting the Preferences file seems to have given me a chance at a fresh start. Many thanks!
