In my _working_ CUPS on Jessie, I have :

Listen /var/run/cups/cups.sock

which I find fascinating, as is _NOT_ the IP address of my 
computer, yet somehow it works anyway. The port scan you did a reply or 
two ago showed you had something listening on UDP port 631, but nothing 
on TCP port 631, which is why printing is not working. 

Indulge us, and add a line to your cupsd.conf as follows:

Listen localhost:631

and restart CUPS and see what happens.

Assuming that works, you are going to want to know why it was necessary 
to add it, and I am afraid I have no idea. I can tell you though, for 
what use this is, it is _NOT_ a direct cause of the wheezy --> jessie 
upgrade. I performed that upgrade (a good while ago, to be fair) and did 
not experience this problem. So in the absence of better information I'd 
have to guess something you did or something else you installed resulted 
in this happening to your conf file. I really have no idea what that 
could be though.
