I've opensuse version 12.2, and after latest apper cups pushed update to version cups 1.5.3-2.4.1 printing to printer from firefox 17.0 , crome 22.0.1229.94, or konqueror 4.8.4 rel-2, results in "/usr/lib/cups/filter/pdftops failed"
I can print to file .pdf or ps OK,
Print to printer from libre office, even M$ office on wine, also Adobe pdf viewer or Okular just fine. I've tried almost all available printer drivers for my HP990c and the results are the same.
I just can't print to printer from web browser!
