[CentOS] [OT] Lexmark T632 info sought

We have a bunch of old Lexmark T63x printers connected to our LAN.  These are
accessed via IPP from our CentOS hosts and via TCP for our MicroSoft work
stations.  Both connections have worked without problems for years.

This past week one of the T632s was replaced and since that time we cannot get
either IPP or TCP to work with it from our CentOS hosts.  It continues to work
for the Windows domain workstations.

I have verified the settings, both printer and network, and everything seems
to match the settings of the original printer.  Nonetheless when the printer
is enabled we get an IPP failure as soon as we send any job to it.

The only thing that I can detect that is different is the printer firmware. 
All of the machines that work have this:

Printer Revision Levels:
Loader 	551.019-0
Base 	551.019-0
Network 	551.087-0
Engine 	E551.413 -0
Panel 	7.02
Font 	8.10H02-U4.0
Tray 2 	10.18-5
Duplex 	23.11-7

The one that fails has this:

Printer Revision Levels:
Loader 	551.019-0
Basic Kernel 	E_YD.014-0
Kernel 	E_YD.014-0
Base 	551.019-0
Network 	551.019-0
Engine 	E551.421-0
Panel 	7.02
Font 	8.10H02-U4.0
Tray 2 	10.18-5

I have no idea what a Basic Kernel on a Lexmark T632 is.  Does anyone know and
if so can you say whether or not this is the source of our difficulty?
