I followed the detailed instructions in the post at this link by Luis Alvarado which explained in detail how to share a printer in Ubuntu 12.04.

Everything worked as it was supposed to after following the directions.

My problem is, when I go back to Printers-Server-Settings, I get the following dialog;

CUPS server error There was an HTTP error: Not found.

Printing still seems to be working but if I want to stop the print server for this printer, how do I reverse the settings I turned on if I can't get to them?

In case it matters, this installation of Ubuntu has HPLIP 3.14.6 installed on. I assume CUPS is also installed since I see a webpage show up if I go to http://localhost:631. I believe it said 1.53 I think.

I am new to Linux so if any other info is needed, please don't hesitate to let me know.

Thanks for any and all help.

Do you mean running Printing and then choosing Server-> Settings? – Elder Geek Aug 6 '14 at 20:57
I am sorry for not being clear. Yes, I went to the Gear icon in upper right, then selected Printers (I believe that is what it was called - I could also find the same by going to the Gear then selecting System Properties I think and then selecting Printers) and from here went to the upper left of the screen where it showed Printing I think. This displayed 2 menus, one being Server. Under this Server menu is where I found the Settings. When I try to open this menu item, this is where I am now getting the error message. – CBR954RR Aug 7 '14 at 14:56

I had this problem as well; from what I've seen it is a recent problem with CUPS that will be patched soon. In the meantime, I was able to do everything I needed by:

1) Pointing my browser at localhost:631, this will bring up CUPS' web interface. 2) Clicking the 'administration' tab. this will give you the ability to edit all options found in printers-server-settings.

808style, Thanks very much for this tidbit of info. I appreciate it very much. Since I don't much at all about Linux, what I can't find when doing a search, I turn to folks like you to enlighten me. Thanks again for your help. – CBR954RR Aug 19 '14 at 15:06
