Hi, Printing from Firefox causes a "Print Preview Error" popup box with the message "an error occurred while printing...", and the resulting page is blank - whether printing to pdf or normal printer. NB I'm not trying to print preview but assume that is a background process. Printing in Chrome works fine. Any help will be apprecited. I didn't find the right solution from the Internet.
