I'll try printing after the configuration after sending this.
Swapping in and out HW contributed to the error with s-c-p (Radeon PCI
in, 3COM NIC out). The NIC that was present for eth0 (3Com) was no
longer present and caused the realtech to get the wrong MAC address or
some related failure. Removing all NIC devices from the configuration
via system-config-network and then starting over allowed the printer to
print without freezing.
Leases were tried via dhclient and failed, then were later successful
and s-c-p proceeded to the next step. This is before reconfiguration of
the network cards.
The test page was successful after getting the NIC working correctly.
