    	I am detecting them, too. I have contacted them by phone, and they say that 
    their mail server has a Jetadmin program that detects printers automatically 
    and about two weeks ago "it started to detect lots of printers all over the 
    world".
    
    	It might be a misconfigured program doing a "discover" to all 192. 
    addresses, (our AS has 194 and 212 address space but have seen only probes to 
    192) but I am not sure (I don't know the program they are using).
    
    	Anyway, I have told them that their server may be compromised and perhaps it 
    is being used to launch attacks (the 20 minute delay looks like a stealth 
    scan). They are going to disable the "discover" feature and we will check if 
    the scans cease.
    
    	I will get back to the list with the result
