Chapter 3
Internet Printing Protocol
8 PrintServer for USB with 4-Port Switch
A printer problem has caused the IPP Server to cease •
responding, and a restart (reboot) is required.
The Server’s IP Address has changed. •
The Internet connection for the IPP Server is down. •
Network congestion causes the connection attempt to •
time out.
If using the supplied IPP Client software, there are two
settings—Retry Interval and Retry Count—that can be
adjusted if you have problems connecting to the IPP
Server.
See the previous section, “Changing the IPP Port Settings”,
for details.
