On Monday morning, my local printer (Xerox Phaser 3320) would not accept jobs ("printing stopped"). I have access to network printers (all Xerox), and had the same experience with them. I have now spent the better part of yesterday and today trying to solve this problem: everything was working fine until I got the weekend's updates. (At least, I was printing just fine on Friday.)
I have scoured this site, Unix.SE, and the internet for "filter failed" problems, but can't find a solution that works in my case. I've tried deleting and re-installing the printer several times, from Settings, and sudo system-config-printer, and http://localhost:631/, and also checked cables, etc., all to no avail.
I have tried using the PPD suggested by the system, as well as the one available from the Xerox site.
I have Win7 in a Virtualbox on this machine, and can (!) print to this printer from Virtuabox.
With the latest re-install, I tried printing a test-page (from the install device settings window), and get this in /var/log/cups/error_log:

I note the problem with libqpdf.so.18, and this is what the location shows:
$ ls -al libqpdf*
lrwxrwxrwx 1 root root 17 Aug 18 15:06 libqpdf.so.17 -> libqpdf.so.17.0.0
-rw-r--r-- 1 root root 751928 Aug 18 15:06 libqpdf.so.17.0.0
lrwxrwxrwx 1 root root 17 Sep 16 04:12 libqpdf.so.18 -> libqpdf.so.18.1.0
-rw-r--r-- 1 root root 784600 Sep 16 04:12 libqpdf.so.18.1.0
Beyond that, however, I don't know what this problem might represent or how to fix it.
I am running (full disclosure) Ubuntu Gnome 17.10 but hope I don't have to wait weeks for some help with this problem. (Please!) I would welcome any suggestions or guidance on further diagnostic steps.
