I'm running XP Pro SP3, Firefox 3.5.7 and doPDF 7. On a fresh instance of Firefox, I can print successfully to a (network) printer. Then I print to doPDF. Subsequent prints to the real printer result in nothing, not even an error. Other applications, e.g. IE7, don't have this problem. Printing starts working again after a Firefox restart but the missing prints never appear.
Ideas?
