Had the same problem. Looking at the output from hp-check -t I found:
hp-check -t ... Current contents of '/var/lib/hp/hplip.state' file: Plugins are not installed. Could not access file: Permission denied
/var/lib/hp actually has permissions 644 after the upgrade to 3.13.2
Changing it manually to 755 (sudo chmod 755 /var/lib/hp) solved the problem for me.
I have reported this also on the hplip bug tracker: https://bugs.launchpad.net/hplip/+bug/1133486
