[cups.development] Sending Print Packets (for lack of a better word) to CUPS

[Michael Sweet]

If you want to print directly, you'll need to do more than stream print data - CUPS (and cupsd specifically) is an IPP-based print server, so you'll need to generate IPP messages and post them using HTTP over the normal CUPS ports.

Some people have setup raw socket listeners via xinetd/inetd that basically pipe their output into lp or lpr, which then generate a Print-Job request for the local cupsd.

Can I simply forward messages to port <cups port> and have it print away?  Or is there a very specific set of parameters/values I need to send once I'm able to open up a socket connecting to the CUPS server on the application side?
