We have had a sudden problem where we are unable to print anything from open vpms and attempting to print anything freezes the whole program. This includes drug labels from the label printer as well as invoices, certificates etc from the A4 printer. We are able to print other documents on this printer from the same computer (eg Word documents) but not anything from open vpms. When we attempt to print anything from open vpms we get the small grey box with "Please wait..." and the scrolling circle symbol but then it freezes. We are unable to click cancel or navigate away from the screen. The only thing we can do then is close the whole page down and reopen in a new window.

We have never had this issue before. Any help would be greatly appreciated.
