This is happening to all my users. I uninstall Reader, run Acro Cleaner, restart, reinstall, run a test print and it works properly for a while, but then it gets an automatic update and the user can no longer print. For one user, I have had to run the above procedure 4 times today for just one user.
Something is broken and it needs to be fixed ASAP. I support over 80 users so this is unacceptable.
