Its not a Win 7 problem. I print PDFs all the time. Reinstall adobe and or printer drivers would be my suggestion.
Yeah, that should only take a couple of hours at most, once you research how to do each step of the process, get it wrong, try again, reboot your computer a few dozen times, etc., etc.
Note: I'm not criticizing you, driftdiver; I think your advice is sound.
What drives me crazy is that pretty much every time I want to print something out (which happens about once every three months) I invariably have to essentially debug the entire printer chain-of-events, which I already did the last time I printed something out.
