I have a jet printer refusing to work after an internal ink leak and cleaning and the replacement of the 4 ink cartridges with a MIR-AUS CISS but my experience is not sufficient to make sense of the CUPS logs.

I have read somewhere that CUPS 1.6 is much better than CUPS 1.5 which I have.

My question is: can I expect to learn something else about the behaviour of the printer if I had CUPS 1.6 installed?

Thank you for your help.

I don't believe there are any diagnostic advantages.

Here's the release notes for CUPS 1.6.x:

See if any changes apply.

Bugs ought to be worked out by now on major distro's I'd think.
