HPLIP

hplip-3.14.4 issue. I could not make hp-setup connect to cups server

Asked by CESAR IZAGUIRRE

I am trying to configure a printer. I run hp-setup, when it comes to "add printer", it says:

"Printer queue setup failed. Could not connect to CUPS Server Is user added to "lpadmin" group(s)" (I already added)

I made the "non-root user" member of lpadmin group,

I would really appreciate your help.

hplip version: 3.14.4 from http://hplipopensource.com
Distro: Back Track 5 R2
Printer: HP Deskjet 2050

In backtrack you have to use a non root user and I do it like that but the problem is at the very end of the process.

Hi,

Sorry to inform you that HPLIP is never tested on Back Track 5 R2 and there is no simple installer provided for the same, however you can try installing it from the source directly. Please follow manual installation instructions of Ubuntu ( http://hplipopensource.com/hplip-web/install/manual/distros/ubuntu.html ) as Back Track 5 R2 has been taken from Ubuntu base code .

The only change I had to do was the location on "Printing" screen. instead of cupsserver.localdomain I put localhost;631
Of course as xyz user and not root :)

Thank you Sanjay! :)
Best regards from Mexico City.

If someone have the same problem don't forget to

1. Open terminal and type sudo gedit /etc/cups/client.conf
2. Copy or type ServerName cupsserver.localdomain.com into text editor, replacing "cupsserver.localdomain.com" with YOUR CUPS server's full domain name (mine was localhost:631)
3. Save the file and that's all
