Having a problem printing to HP Printer. Seems to have started recently, ( I haven't upgraded the RAM nor have I added new programs) Window pops up with message "invalid page fault spoolss.dll stack fault. I have tried to update the spoolss.dll library and that doesn't work. I can print from some files on the computer but if I try to print off the internet this message appears. Also I lose the printer and have to restart the computer to get it back. I think this is probably something easy to fix, but not for me. HELP
