CUPS - Remove Password Prompt

Question

I have a printer installed on an ubuntu server (12.04 LTS)

I can print items with no issue, but it always prompts for a username and password, which is super annoying.

I tried everything I could find about it online but nothing seems to remove the prompt.

I set DefaultAuthType to None in /etc/cups/cupsd.conf, still a prompt.

also just read this post:

Cups is always asking for password when printing on a certain printer

but that didn't help either sadly, though for me I only have one printer so I'm baffled on what to do now.

Thanks.

EDIT:

Here is what my CUPS files look like:

printer.conf

Solution

Try to change in /etc/cups/printers.conf

AuthInfoRequired none

I have installed hp2015 and don't have problem

<DefaultPrinter hp2015>
UUID urn:uuid:c7c39f9e-7dc7-3a45-7531-fc4222d08420
AuthInfoRequired none
Info hp2015

</Printer>

and this is my cupsd.conf

You can check your part of /etc/cups/printers.conf and /etc/cups/cupsd.conf. I don't have problem with authorization when printing.

AuthInfoRequired isn't on there, so I'll try to add that tonight when I have access to my server (its a home server so its not publicly broadcasted) and see if that does it.

that didnt work either, I altered my question to include what my config files look like.

Try to replase your cups.conf with my. Restart cups and try to print.

Could you correct your line breaks?
