I have a similar problem. For me, I can not print from a
Macbook. Under some conditions, which I cannot repeat, I have gotten
an error message saying that the printer has only a self signed
certificate. When I convert the pdf to a .ps format, which I think
cannot contain a certificate, I am able to print. I think my problem
relates to Apple/CUPS push toward World Dominance. YMMV
OTOH, it may be a bug in one or more packages that involve certificate
handling. But I am clueless about certificates. It was news to me that
CUPS cares about certificates. (or does it?, I don't know)
