The TCP/IP address ranges for printer detection can be entered here. Two methods for automatic recognition of the network printing systems are available.

For recognition of the network printing systems, please enter the TCP/IP addresses or address ranges into the input fields of your preferred detection method. For accepting your configuration settings please click the 'Apply' button.


Source Identifier

Chose the desired source identifier here for which you want to configure the following parameters. Please note that network ranges and IP addresses for printer detection of source identifiers must not overlap.


Schedule

Within this menu it can be specified which timeframes and time intervals should be used from the FSM client software for automatic search of new printing systems within the configured TCP/IP addresses or address ranges, and whether new recognized printing systems should be automatically monitored by the FSM client software.

By clicking the 'Search now' button, an immediate search and detection process can be initiated.


Network Ranges

Here you define networks and network ranges, in which the FSM client will search for printers. A network is defines by its IP address and its subnet mask. Within a network, a finite number of host addresses exists. Example:

Host address:   192.168.178.100     
Network address:   192.178.178.0     
Subnet mask:   255.255.255.0     

The address in the example above describes a class C network. The beginning part with 192.168.178 - built of 3 bytes - always remains constant, while the last byte addresses from 1 to 254 devices. Values 0 and 255 are reserved. The constant part is the network address, consisting of 3 bytes, that is 24 bit. This allows writing the network address using 2 different notations:

Network address:   192.168.178.0     
Subnet mask:   255.255.255.0     

or using the CIDR notation (Classless Inter-Domain Routing) :

Network address:   192.168.178.0 / 24  

First enter the network address or a host address within the network, e.g. the host address of the computer on which the FSM Client software was installed. Your network administrator will give you the corresponding subnet mask or CIDR number. One of both will be sufficient to enter, the other one will be calculated automatically.

More examples for CIDR notation and subnet masks:

CIDR   Subnet mask      Available host addresses  
/8       255.0.0.0       max. 16.777.214  
/12       255.240.0.0       max. 1.048.574  
/16       255.255.0.0       max. 65.534  
/20       255.255.240.0       max. 4094  
/21       255.255.248.0       max. 2046  
/22       255.255.252.0       max. 1022  
/23       255.255.254.0       max. 510  
/24       255.255.255.0       max. 254  
/25       255.255.255.128    max. 126  
/26       255.255.255.192    max. 62  
/27       255.255.255.224    max. 30  
/28       255.255.255.240    max. 14  
/29       255.255.255.248    max. 6  
/30       255.255.255.252    max. 2  

Then chose the scan method. A broadcast usually will only work if FSM Client and printers are residing in the same network. Broadcast has the advantage of sending out one data packet only to make all devices answer. In case a network is attached via a router, it is most probable that this router will block broadcasts into this network. Then you have to use Brute Force. This will connect to all possible host addresses explicitly.

Using Brute Force method the number of addressed devices might be reduced by restricting the search range. Therefore enter a From IP address and a To IP address. The search then will only go through this restricted range of addresses. Using the button 'Add' you may add several partial ranges of one network as also several complete networks.

Searching sends an UDP package for printer identification and waits for a response of a potential printing system. Usually printers answer on SNMP queries made on UDP port 161 and use the SNMP community named public. If you want to detect SNMP Extenders for local printers set the UDP port to 51950. The buttons 'Std.' and 'Ext.' will set the content of the UDP port edit field to the required value.
