Comment 7 for bug 218921

This bug shows the same errors I am getting about hpssd socket connection refused. Also the denied_mask="::rw" section as well, and usblp0 removed. Though printing locally still works after the "usblp0 removed" portion is displayed sometimes.

Sometimes I can print from a remote system, and sometimes I can't. What does happen is that my printer is completely locked up once a print fails, and I have to unplug power to printer, unplug usb, replug power, power up, then replug usb, in that order specifically, to make it not lock up again, then sometimes the first print from a remote system will lock it, sometimes not. And sometimes, after a reboot of the printer that way, it will go ahead and print the remote print job from the queue, the very one that crashed it in the first place. I am not printing from samba remotely, but via http cups server.

disabling app-armor did not product any definitive results, still getting lockups 99% of the time.

I believe this bug to be closely related to https://bugs.launchpad.net/ubuntu/+bug/241781

Many people are hinting at a permissions problem, but I have no idea how to fix something like that.
