Hello, I cannot print from firefox to cups. I use cups 1.4.8-1 and firefox 5.0.1-1. The message in the cups error log is as follows: Returning IPP client-error-document-format-not-supported for Print-Job (ipp://localhost:631/printers/dj5550) from localhost I use the hpijs printer driver to print to a HP Deskjet 5550 printer. Printing the test page from the cups web interface works flawlessly. Printing from the chromium web browser does not work too. The error message is the same. The only way to print a web page for me is to print it from firefox to a PDF file and then print the PDF file from epdfview. This works. The problem existed before the latest cups update with cups version 1.4.6-1 too. I cannot exactly tell when it started. I only remember that some month ago I could print from firefox without problems. Has anyone an idea how to fix this? Regards Markus
