connected LAN and printer is set to DHCP mode as well, then it will use the internal pre-set address
(IP: 10.0.0.1, Subnet Mask: 255.255.255.0) automatically.
It is suggested that printer’s IP set to static in actual usage, which can cut down the time when
initializing the Ethernet interface as the printer is turned on and prevent IP conflicts (The dynamic
address used in printer may conflict with another one). The network segment part of the IP address
and Subnet Mask must be the same as those of PC connecting with a printer. For example, the
address of working PC is 192.168.0.1/255.255.255.0 (IP/Subnet Mask),then which of printer should
be set to 192.168.0.x/255.255.255.0（x=2~254 and should avoid the IP in used. It is not restricted
for NetFinder to search printers in the same network but different segment parts (can not stride
gateway). Relative glossary of IP address may refer to corresponding information.
2) Setting printer’s IP address
Select the printer information to be modified (black frame appears), click “Assign IP” button. Set the
IP in the dialog box appearing.

Check the “Use DHCP” if need to assign dynamic address, the settings above will be disabled
automatically. Please make sure there is a DHCP server in the network, or the printer can not
receive an effective IP address.
When to specify static address, uncheck “Use DHCP” and fill in “IP address”, “Subnet Mask” and
“Default Gateway”. If there is no gateway in the network, fill 255.255.255.255 in the “Default
gateway”. “IP address” and “Subnet Mask” should obey the assigning rules of local LAN (Ethernet),
please enquire the administrator of networks which the printer connects to for more details.
Click “OK” to send address setting information to the specified printer. The printer takes response
after “Close this window on success” is checked, and then this dialog is closed automatically. Select
“Reload Timer” then the software will wait for the printer’s response. Generally, printer will take
response in a circle time if network connection is correct.
Click “Cancel” if you abandon the modification.
Click “Search” in the main interface again to update printer information after modifying the printer’s
IP address.
3) Report printer’s IP address
Report the printer’s IP address, which will be used in the section “Newly-install printer network driver”
or “Upgrade-install printer network driver (setting driver’s network port)”.
2.11.3 Installing Printer Network Driver
The ways of installing network driver are divided into Newly-install way and Upgrade-install way
according to whether the PC installs the printer driver or not.
If the printer driver hasn’t been installed on the PC, adopt Newly-install way whose steps are shown in
“Newly-install printer network driver”.
If the printer driver has been installed on the PC, adopt Upgrade-install way whose steps are shown in
“Upgrade-install printer network driver”.
1. Newly-install printer network driver
1) Click “Start” →“Settings”, select “Printers”.
2) Click “Add printer”, then come out a window of “Add Printer Wizard”, click “next”.
3) Come out a window of “Add Printer Wizard”, then please read the select direct carefully. Such as,
select “Local or Network Printer”, then click “next”.
4) Come out a window of “Select the Printer port”, select a port you want your printer to use. For
example, select “Create a new port”, select “Standard TCP/IP Port” in the port, click “next”.

5) Come out a window of “Add standard TCP/IP Printer Port Wizard”, click “Next”.
6) Come out a window of “Add Port”, enter the IP address reported by the “Setting printer’s IP address”
in the “Printer Name or IP Address” column. Take IP address “192.168.0.240” for example. “Port
Name” is created automatically after finishing filling in IP address.
7) Come out a window of “Additional Port Information Required”, select “Custom” in the “Device Type”,
and then click “Settings”.
8) Come out a window of “Port Settings”. Affirm that “Port name” and “Printer name or IP address” are
correct, “Protocol” is “RAW” and “Port Number” is “9100”, click “OK”.
