Hm, that is a bit sad. I once configured my Netgear PS101 to have IP
192.168.99. I can ping it - like you:

$ ping -c1 192.168.0.99
PING 192.168.0.99 (192.168.0.99) 56(84) bytes of data.
64 bytes from 192.168.0.99: icmp_seq=0 ttl=30 time=3.15 ms
 
--- 192.168.0.99 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 3.155/3.155/3.155/0.000 ms, pipe 2

A scan against the print server's LPD port shows it open:

$ nmap -v -p515 192.168.0.99

Interesting ports on netgear.dogma.lan (192.168.0.99):

Are you able to connect it in a different network to test connectivity
from a different system? Maybe even a Windows[tm] system and then to use
the Windows[tm] drivers/tools for that device?

Normally I would not suspect a coincidence with a print server break
while switching from FC2 to FC3. The last recommend I can give is to
flush firewall rules with

service iptables stop

to be sure, nothing blocks network traffic. But as you say the print
server states no ports open, this shouldn't be the case at all. So there
leave just the ordinary, basic things: check your cable, switch the
print server off for some time by taking off power (for longer than a
second, time enough that stored power can went away), check ethernet
cable connector fit in the print server plug.

Hope something will help.
