[CentOS] Printing: network host busy

I have 5.1. The other day I was printing and the job crashed. I cleaned
the /var/spool/cups, but I am still getting the:

network host is busy, will retry in 30sec

It's a dlink print server, that has worked very well for the last 3 years.
I have restarted but the print server and the printer.

Any suggestion?
