I am unable to print any web page content in Fire Fox (FF), however the same web content prints in Explorer. HP 6520 printer acts like it is going to print, but a window pops up saying "an error occurred while printing" and the printer spits out a blank page. I explored FF "about:config" as recommended in various articles; none of the cited issues exist and everything seems okay. I tried resetting FF print to default settings with no change. FF used to print, but at some point it developed this problem. Unfortunately I can't pin point when it started or whether the problem came after an update. It is a major pain to run Explorer to print something.
