Why should you bother to do a STFW while there are people on this list who will feed you today and tomorrow

I don't know what a STFW is, but I guess it is not very nice. Why do you say that? Wade is new, he wants to know what CUPS is, what's wrong with that? The kind of thing you usually find on the web is rather technical, so it is OK to ask for a simple explanation. Linux is supposed to be community where we help each other.

I strongly agree however in order to gain the maximum benefit it is my understanding that the person who needs assistance on a subject

a) has done a preliminary research of information b) either has not found anything related to his question or the information he/she has founded is highly technical the person is confused or is inadequate to solve the problem or answer the question. c) under these circumstances the person who needs further assistance should tell the steps he/she has done so far and where he is getting lost and ask for assistance.

This way it is easier to make suggestions and offer asssistance. I could have easly said Common Unix Printing System, which answers the question in a very vague manner.

Chineese proverb

"Give a man a fish you feed him for today "Teach a man howto fish you feed him for his life"

I prefer the second since I do not like going fishing everyday to feed someone

OK, I agree with the proverb, but with a technical subject like that, I find it nice to give people a starting point. Now that Wade has a general idea of what a printing server, he can STFW with better chance of success. ;-) - -- Thibaut Cousin E-mail : cousin@in2p3.fr Web : http://clrwww.in2p3.fr -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE9yO/fv1vqsTa1E4oRAuQyAJwKGMc+pyFPStbZWM1NeHV1DQMmYgCfQK7d vNFYoPUoYxNe9r/Dr/0T1yc= =5dPG -----END PGP SIGNATURE-----

Thanks for your more friendly answer. I agree with you that someone here can give a nice simple starting point. I too want to know more about CUPS. I have already seen info on it, enough to know that it is a printing system but what I don't know is what is the difference between CUPS and LPRng and why I should use one or the other. After the not-so-friendly reply, I don't know if I would bother to post my question.

First, let's say the CUPS server gives access to much, much more configuration options for your printers. For example, in my lab we have a new printer. A real monster. But with LPRng, I can print only in simplex (one-sided) because all I can do is send a postscript file to the printer through the network (it is called a TCP printer, because it has its own IP address). With CUPS, I can choose the printer model locally on my printer and play with the parameters (recto-verso, for example) remotely. Next, CUPS is much better at using PPD files, if I understood that point correctly. A PPD is some kind of driver, a "Postscript Printer Description". If you have the PPD file of a printer, you can make it work with CUPS. The manufacturer can have that file. It is a text file, so it is the same on Windows, Linux or MacOS. For example, one of my colleague has a Macintosh. The printing system on MacOS is also CUPS. So he got the PPD files from our printers on the Windows server, put them on his Mac and he could print without having any manufacturer CD with Mac drivers. On the server side, CUPS is able to manage printer classes. For example, if you have one printer, instead of having several separate queues for various qualities, you have one "printer class" (your printer) and to make all your sub-queues you need only to provide the parameters that differ from the real printer. I guess a real system administrator could tell you much more than me about it, but I hope you get the idea. The only thing that bothers me with CUPS is its tendency to halt print queues for no reason. Then you need to log in the server and restart them by hand. Oh, that's another good point with CUPS: you can configure and play with the server very easily. Type "http://localhost:631" in your browser, login=root, and you have a web interface for the CUPS server. You can restart queues, configure them, etc. - -- Thibaut Cousin E-mail : cousin@in2p3.fr Web : http://clrwww.in2p3.fr -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE9yRdGv1vqsTa1E4oRAgRpAKCrKN4sQc41bcGnhXtoWTgcGAHwRgCeMQQj xvc1lDgrm+vrlzKoci4N5pw= =lYrN -----END PGP SIGNATURE-----

CUPS is a printing system. What does it mean? In Linux, printers are represented as queues. Each queue can be a different something, you send the file to a server in memory. This server processes the file and sends it to the required queue. It is nice because local printers, remote printers (of whatever kind) just look the same for the user.

This server is CUPS (it could be LPRng, LPD, etc). It is very complex

compared with older systems like LPRng and is able to process documents before they are printed in a very nice way. Some KDE printing features (in the printing dialog) work only with CUPS.

I hope you get the idea. Otherwise just ask again. ;-)

Thibaut: That is the finest answer/description of CUPS I have read! Thank you. I have been searching the web for weeks to get just such an answer. That now gives me a starting point to go back and figure out just how CUPS does what you say it does.

I thank you for being such a gentleman and answering the question.

If my answer was useful to you, then I'm happy! ;-) - -- Thibaut Cousin E-mail : cousin@in2p3.fr Web : http://clrwww.in2p3.fr -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE9yhwKv1vqsTa1E4oRAn/8AJ480qaR+jRPyGqRKHYgeh4UrV8WKACeLMss X8mUCn9BnI/j/n8XSM7ubBQ= =uyW9 -----END PGP SIGNATURE-----

That would be nice but it doesn't work here. As both a user and as root it fails.

Mozilla returns:

The connection was refused when attempting to contact localhost:631

Konqueror returns:

An error occured while loading http://localhost:631:

Could not connect to host localhost (port 631)

This is with SuSE 8.0.

Thanks for the clear explanation.

CUPS is not installed by default in SuSE 8.0. What I said will work only if the full CUPS server is installed (if I remember correctly, there are four packages cups-something to install).

I thought of that after I posted. :( I probably did not install CUPS.

The printer works.

I'll stand still while you hit me with the cluebat.

If you can write a program that does that remotely, I'll bow ;-) The package you probably have is called "lprng". - -- Thibaut Cousin E-mail : cousin@in2p3.fr Web : http://clrwww.in2p3.fr -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE9yiUtv1vqsTa1E4oRAuSUAKDVyiEVlzkYtlnw1AR4K5GcRpuVfACgsJ9G LwJUSEo/7ygrNI/h0bVJdUs= =q5XN -----END PGP SIGNATURE-----

The package you probably have is called "lprng".

You got it: rex@syntax:~> rpm -q lprng lprng-3.8.5-49

Now that you have provided the name I found it in the reference manual.

Thanks,

For future reference, in this case you could have done the following rpm -qf /usr/bin/lpr That would save having to guess at all the possible packages that could be used for printing. It would have returned the package name that contains the file /usr/bin/lpr. -- Kelly L. Fulks Home Account
