From: Ron Johnson on 3 Apr 2010 20:40 I know that lpr is BSD and lp is SYSV, so lpr is needed for compatibility, but when comparing the man pages, lpr seems to only be a "half-the-features" lp. -- "History does not long entrust the care of freedom to the weak or the timid."

It seems to have less options, yes. But both ("lp" and "lpr") are included in CUPS so I see no problem here, we can use whichever best suits our needs.

Right. But, absent old or cross-platform scripts which need to run on both Linux and BSD, what *benefit* does lpr have over lp? -- "History does not long entrust the care of freedom to the weak or the timid."

In todays systems I fail to see a clear difference on both :-? This article may help: *** 8.17 Printing Protocols (lpr and lp) http://docstore.mik.ua/orelly/networking/firewall/ch08_17.htm The System V lp printing system doesn't really have a remote printing component. When it does remote printing, it usually does it by handing the job off to a BSD lpr printing system, or by using the BSD rsh command (which is often called remsh on System V systems, because such systems have another program called rsh that does something else entirely). *** Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
