Cups running on Ubuntu 15.10 server and so far so good.

When an OS X device tries to print through the ubuntu cups server, I get this error:

IPP client-error-not-authorized for Create-Job

On the OS X device in the print job I get the message:

Hold for Authorization

Made the standard tweaks to cupsd.conf and printers.conf (see below), but no joy.

Any cups experts have any advice?

Thanks

I noticed there was a continuous error 'Create-Job client-error-not-authorized: The printer or class is not shared!' in the CUPS errors logs when a print job was queued on the local PC printer queue. I removed the HP laserjet 6MP printer under CUPS admin again and installed it as ‘Share This Printer’ with the settings. This time I used the PCL 6 driver with its default options. That fixed it. A print test job worked from the PC. Re installation of the IPP printer was not required on the PC.

After MUCH searching found the problem.

In printers.conf changed

AllowUser all

to

AllowUser

and yes, that is all that I needed to change...weirdo!
