[cups] Printing CCITT and JBIG2 encoded images fails

[Michael Sweet]

Emilio,

The CUPS error_log will show which filter(s) are used for the job, at which point you can determine which packages are involved. IIRC the cups-filters PDF to PostScript filter (which will likely be invoked for this driver) can be configured to use either, so look at the /usr/lib/cups/filter/pdftops script to determine which program is getting used.

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.
