Emilio,

If the driver is the same, it is probably a change in poppler or Ghostscript causing the problem.

I am using CUPS 2.2.4, Arch Linux 4.11.9-1 and a Canon ImageRunner C1028i and installed the driver from here: https://aur.archlinux.org/packages/cndrvcups-lb-bin/. Plain text PDFs and PDFs containing JPEG encoded images print flawlessly.
