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.

I see usb* in mine

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.

Hello all, and thankyou.

I notice that the example given quotes lib64, mine above doesn't have any reference, does this matter? In fact my Peppermint 7 is 64 bit.

Just a thought - did you install the 64-bit cups package?

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 .

Does this matter much?

Regards Ant

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.

Regards Ant

Hello Ant. You probably have, but I'll ask anyway... Have you tried simply enabling the printer? To enable your printer:


Switching to Ubuntu is not going to help as the issue seems to be with CUPS, not with the OS.

@erik2282: Check post #15 where the following status message was reported (in /etc/cups/printers.conf)

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

I hope that helps someone.

That's the unified driver I use for my Samsung CLP320.

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!

Meantime I really do appreciate your assistance.
