60 | * LPD "mini-daemon" for CUPS. This program must be used in conjunction | |
61 | * with inetd or another similar program that monitors ports and starts | |
62 | * daemons for each client connection. A typical configuration is: | |
63 | * | |
64 | * printer stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd | |
65 | * | |
66 | * This daemon implements most of RFC 1179 (the unofficial LPD specification) | |
67 | * except for: | |
68 | * | |
69 | * - This daemon does not check to make sure that the source port is | |
70 | * between 721 and 731, since it isn't necessary for proper | |
71 | * functioning and port-based security is no security at all! | |
72 | * | |
73 | * - The "Print any waiting jobs" command is a no-op. | |
74 | * | |
75 | * The LPD-to-IPP mapping is as defined in RFC 2569. The report formats | |
76 | * currently match the Solaris LPD mini-daemon. | |
