best practice to discover the only printers of the entire network

Hello everyone,

I have a question about best practice on discovery schedule to retreive only information on Printer device.

into customer network we are using A ip addresses class (10.0.0.0) to manage the device.

My question is:

What is the best pratice to execute a Discovery on entire network to retreive only printer information, without know ip range address?

Thank you so much!

Regards,

Gaetano

 

EDIT:

I also have a doubt.
Consider the following scenario.

Step 1:
On January 1, 2017, a discovery is made (using an IP range ranging from 10.0.0.1 to 10.0.0.255) and 100 printers are registered with their IP addresses.

Step 2:
Discovery is blocked ... and starts again after 2 years.
1 January 2019, where about 60 printers have changed their IP address (which is defined in a range of different IPs, for example: 192.168.0.1 to 192.168.0.255).

Using the discovery schedule, configured on 1 January 2017, the 60 printers that changed IPs would not be taken into consideration.
For this I would like to understand the best way to discover all the printers on the network, even if these dynamically change the IP address

I believe that the only way that leads to a correct reconciliation is the MAC Address using the Hardware Rule that starts on Printer type CI

Thank you for answer.

If I didn't want to rely on the type of CI to be discovered, but on the IP Ranges. What is a good practice? Have Discovery schedules that cover a not too large number of devices? How many discovery schedules should I have?
