FF is driving me batty... I used to be able to print to .pdf or paper just fine, but around 6 months (or so) ago this functionality vanished. Print dialogue appears, allows me to format layout, pages, etc, but when I click "OK"... no joy. The very first time I try to print to .pdf or paper from a fresh install of FF, I get a script warning note; allowing the script to continue brings up the script warning repeatedly, stopping the script... well, stops the script and then nothing productive happens. If printing to paper, no response from the printer (print dialogue doesn't open, no indication of data transfer to the printer). If printing to .pdf, a .pdf file is generated but is "corrupt or in a format Preview doesn't recognize" (also cannot be opened by Adobe). Clicking "preview" has no effect - the "print" dialogue box disappears but nothing else seems to happen. Subsequent attempts produce no script warning but otherwise the same results. I'm currently running FF 3.6.12, Mac OS 10.5.8. Doesn't matter what website I try to print, or whether I use FF's "print" command or a "print this page" option on a webpage. Printing to either .pdf or paper works fine from Safari. Resetting print.print_printer from about:config (by right-clicking and choosing "reset") removes this line completely from the about:config list, and apparently requires me to re-install FF (anyone know how to put that line back in without repeatedly re-installing?). Any brilliant ideas? I don't personally think printing from a web browser should be quite this problematic...
