samba - Mar 2006 - reference docs

I found this:
http://technet2.microsoft.com/WindowsServer/en/Library/78a4be20-3f57-4b8d-a921-
ac5d93665ff41033.mspx
It?s a reference document saying that microsoft print server with hardware 
like the HP/Compaq DL560 or DL580 with 1.5GB RAM, high-performance disks and 
sufficient network throughput can host approximately 1,500 printers, serving 
5,000-10,000 customers.

Maybe could I find some information like this about samba/cups print server?
