Did you look at the error/access logs in CUPS? Anything interesting there? I notice in your lpstat output that it shows "accepting requests" and "disabled" occurring at the same time on Saturday. Seems a little odd. On my system with a working printer (HP), there is a usb file in the /usr/lib/cups/backend/ directory so...? If you don't resolve this, you might try re-installing CUPS but that's just a guess on my part. Maybe someone else will have a better idea. Good luck.
As already noted, you're missing a crucial CUPS backend (needed for USB-connected printing). This is normally supplied as part of the cups package. I'd reinstall cups accordingly.

Rep:
Are you trying to print a test page from within cups configuration at localhost:631. You can also start and stop the printer from within cups. You may just need to start it.
Hello Ferrari, I don't recall any options but my cups is about 2.1.2 whereas the ?source has now changed and the latest is about 3.1.2. My Synaptic only mentions, and updates, 2.1.2 .
Hello everyone, thankyou all for your interest and help. Nevertheless I don't feel I've made much progress so I'll try another distro, probably Ubuntu.
I have seen this error: Backend /usr/lib64/cups/backend/smb does not exist! twice in the past month.
What I found is that the symlink between smbspool and smb did not exist in: /usr/lib64/cups/backend
However adding the symlink did not resolve the issue. I had to ALSO go into: /usr/lib/cups/backend
and create the same symlink. Here is what I had to do:
Solution for future CentOS 7 builds:
cd /usr/lib64/cups/backend --If directory does not exist you have to make it.
ln -s /usr/bin/smbspool smb
**and**
cd /usr/lib/cups/backend
ln -s /usr/bin/smbspool smb
Hello all, it's official - bits of my brain have premature senile decay, bit of a drag! This hasn't gone away, I'm just waiting for a chance to pull myself together!
