Okay. This helped quite a bit. Was able to install the 2530 printer at the IP address via CUPS, but it will not respond to any print request. Print jobs appear in the queue (lpq), but never leave. I resort to lprm them to clear the queue.
From the CUPS URL you gave,
http://localhost:631, there is a button to release the job, and after selecting this, it still does not print. I wonder if this is related to what I see in printerdrake, the printer shows up as "Configured on other machines" rather than "Configured on this machine". Could it be that the printer software is not really a compatible CUPS server?
Your URL for openprinting.org seemed to confirm that this printer will work with Linux, but I cannot get it working yet. Will keep investigation and trying.
