hello forum,

I use debian lenny (kernel 2.6.26-2-686)

I am a bit confused when it comes to printing. If I issue the command 'lpstat -p -d' I get a list of available printers. When I look at the list that cups knows at http://localhost:631/ it is a completely different set.

I print with the lp command, which is part of the cups-client package. The printer I can use are the ones that lpstat lists, but I cannot find this list in a config file.

Have I installed two conflicting packages? What must I do to add a printer?
Right now I use the cups web interface, but the added printers only appear in the web interface and in /etc/cups/printers.conf. Both lp and lpstat know nothing of the new printer......

any hint welcome!

Do the printers appear in CUPS at http://localhost:631?

You could try using the 'ipp' protocol in the cups web config.

thank you both for your reply.

Using the web interface http://localhost:631/, I had added exactly two printers using the ipp protocol. These two printers are the only two that appear in the CUPS printer list and are the only printers that appear in /etc/cups/printers.conf.

The lp command doesn't know these two printers and the lpstat command listst 4 other printers. These 4 printers I can use with lp, but I cannot find a config file where they are defined nor can I remember how I added them. They don't appear in /etc/printcap. Applications like iceweasel and oowriter show me the same printers when I issue a print command.

It seems I have installed two printing systems, but I do not know enough of printing to know where to start.....

Maybe this is relevant info:
I found this in the acces.log from cups:

Probably the errors are part of the problem and explain why lp doesn't see the printers that are added in the web interface? Still I don't understand where the printers that lp is aware of are coming from....

Ruud

OK, found it.
The printers that lp found where the ones that were defined on the server as deffined in /etc/cups/client.conf. I changed the client to my local machine et voila: the lists were the same.
The lists of printers on the client were not available via localhost:631/printers, but via http:my.server.nl:631/printers.
Spent some time on it, but will never forget the answer to this question
