Yes I know that Firefox ignores Window's 'default printer' setting, and I have used Firefox for years, and it always knew the correct printer. Today it suddenly picked a different printer (a fax virtual printer). I changed it to the correct printer, printed up the form, closed Firefox, opened it back up, and it DID NOT remember the last printer used. Then I searched the online answers and did the about:config thing, and there was no "print.print-printer" setting (despite using the printer with Firefox for years). there was a "print-printer" setting, and it listed the CORRECT printer.
