The IPP is the native protocol of CUPS: Therefore no extra daemon is needed to receive IPP print jobs. The CUPS daemon listens for IPP requests on port 631. Port 631 is the default port for the IPP. Depending on its configuration it also accepts SSL-encrypted IPP, usually on the SSL-port 443. IPP clients can be other machines running Windows, GNU/Linux, Unix, or MacOS X with CUPS.
On the Windows computer, go to Control Panel->Devices and Printers and choose to ‘Add a printer’. Next, choose ‘Select a shared printer by name’ and type in the location of the printer:
ipp://hostname:631/printers/printer_queue_name
