Since i updated my users to 9.4 they are having trouble printing labels from usps.com. When a user clicks the 'print label' button a print dialogue should pop up. This only works for the account that I used to apply the update. If any other user logs in (restricted or admin) they only get a blink of the screen and no print dialogue pop-up. Unchecking the 'show pdf in browser' option is a workaround, but my users want it to work as it had been before the update. Suggestions?
