Java - List all network printers on LAN

Question

I need to use Java to get a list of all the IP addresses on the LAN which belong to network printers. I don't need to print to the printers, I just need to find all of them. This is for an android application.

Just to be clear, I'm not trying to find the network printers which are configured on the local machine. I am trying to find ALL the printers which are available on the network.

I've tried http://www.velocityreviews.com/forums/t152882-dynamic-network-printer-discovery-and-administration-via-jcifs-samba-org.html already, and I am having trouble with getting the root smbfile to use that code, as my code will be running on multiple domains and networks so I can't hardcode it, and I can't figure out how to find the current domain using jcifs.

Answer 1

Finding "All" printers is fairly tall order.

However I would suggest using SNMP to walk the known ports.

a good SNMP implementation cat be found at

and this site has a good explanation of what you are looking for
