CUPS 3.0

CUPS 3.0

CUPS 3.0 eliminates printer drivers and moves to a new modular architecture:

• cups-local:
  • Commands: lp, lpr, lpstat, cancel, etc.
  • Local Server: runs as user, IPP domain sockets/D-BUS/XPC, only temporary queues, basic spooling and filtering/rasterization, limited job history
• cups-sharing:
  • 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
• libcups:
  • Library: libcups, as exists today
  • Tools: ippeveprinter, ippfind, ipptool, ipptransform

Both the local and sharing servers are based on PAPPL.
