17 * main() - Process an incoming LPD request...
18 * create_job() - Create a new print job.
19 * get_printer() - Get the named printer and its options.
20 * print_file() - Add a file to the current job.
21 * recv_print_job() - Receive a print job from the client.
22 * remove_jobs() - Cancel one or more jobs.
23 * send_state() - Send the queue state.
24 * smart_gets() - Get a line of text, removing the trailing CR and/or LF.
28 * Include necessary headers...

46 * LPD "mini-daemon" for CUPS. This program must be used in conjunction
47 * with inetd or another similar program that monitors ports and starts
48 * daemons for each client connection. A typical configuration is:
50 * printer stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd
52 * This daemon implements most of RFC 1179 (the unofficial LPD specification)
55 * - This daemon does not check to make sure that the source port is
56 * between 721 and 731, since it isn't necessary for proper
57 * functioning and port-based security is no security at all!
59 * - The "Print any waiting jobs" command is a no-op.
61 * The LPD-to-IPP mapping is as defined in RFC 2569. The report formats
62 * currently match the Solaris LPD mini-daemon.
