Hello i'm trying to identify all printers on a network.

Based on some research i found that to do so i have to check the sysServices if it does not support L2 and L3 then i should check for printer MIB.

and in some posts i found that by getting the SysObjectID i can know what kind of device i have
can any one tell me how could Ividentify if the device is a printer using the SysObjectID ?

thx in advance.
