Safari 12.1 not opening print window (SOLVED)

Since Safari 12.1 I have been having a bizarre problem when trying to print anything from the Safari Browser. Usually on Command - P or hitting the print menu option, it opens a new window with a preview and some options for Printing. But since 12.1 nothing happens except a sound alert. After trying all kinds of stuff, it seems to be a bug with Javascript call Window.print() command which Safari does not execute. At last, I did have success doing the following: Go to Safari->Settings->Security and deactivate JavaScript button. Then go to ->Tabs and activate "Open new tabs or window in foreground", then go back to Security and re-activate JavaScript option. After relaunch of Safari the problem disappeared and now I can print again from Safari as ususal. I hope this helps.
