Cups server error I cannot resolve

sudo1 · 05-07-2019, 02:36 PM

For about 2 months now, I cannot seem to get my cups server to connect for my hp printer. Using Linux Mint 19 system. I'm fairly new to linux systems. I have researched endless sites and still I'm at a loss. Any help is greatly appreciated. I've attached the screenshots of the errors.

Going to need more info, like printer model and connection method (wireless, usb, etc). Also, do you have the hplip package installed?

sudo1 · 05-07-2019, 02:54 PM

Okay. My computer system is a dell optiplex with linux mint 19 installed. the printer is HP office jet pro. I have tried usb/wireless.I have the hplip package installed.

CUPS server name is showing a path, that doesn't look right

sevendogsbsd · 05-07-2019, 03:02 PM

Agree, should be an IP. What happens when you plug localhost:631 in a browser? what do you get back?

From what I can tell the errors look normal because either the cups server is not running, is not installed or maybe the firewall isn't allowing a connection. What happens when you run the command.

Code:

sudo systemctl start cups

When I plug localhost:631, the address reads as "unable to connect to server localhost:631". I turned off my firewall for a few, and I still receive that "unable to connect" address. When I type "sudo systemctl start cups", and enter my password, it is accepted in terminal and waiting for the next code I think? Cups is not running or is disabled I think.

If nothing happens and all you see is the command line prompt then cups started properly. You can verify by typing in the command

Code:

 sudo systemctl status cups

You can enable cups to start at boot time by running the command

Code:

sudo systemctl enable cups

Now try adding your printer using the printers wizard.

Okay, when I add "sudo systemctl status cups", a list comes up, and at the bottom in red, it says failed.

"Failed to start CUPS"

Can you post the list?

Can you please paste the entire command-output text here please (use shift-ctrl-c to copy it from your terminal and then ctrl-v to paste it here).

If possible, please do that within CODE tags (see https://www.linuxquestions.org/quest...og.php?b=36313).

For example:

Code:

$ sudo systemctl status cups
.... output....

Just a quick note that if you expand your terminal to a larger size (full screen, perhaps), and then run the command again, then it won't truncate the text at the right-hand side as it has done above. In saying that, I'll now hand you back to the safe hands of michaelk to analyse the output.
