I've apparently clicked something somewhere that has caused anti-aliasing to be turned off for all images and text in all my PS files. Images that were printing correctly last week now are printing all fuzzy; before printing this can be clearly seen on any part of the file.

Every place I can find that has an anti-aliasing choice (text tool, lasso tool, etc) shows that anti-aliasing is turned on.

I have read everything on anti-aliasing in Help, but I can't find any general anti-aliasing switch that would effect everything.
