• Local Server: runs as user, IPP domain sockets/D-BUS/XPC, only temporary queues, basic spooling and filtering/rasterization, limited job history
• Sharing Server: runs as root, IPP domain/TCP sockets, only permanent queues, advanced spooling and filtering/rasterization, job history and accounting, push/pull/release printing, authentication, web interface, configurability
• Library: libcups, as exists today
