Starting Cups automaticly

[GerardV]

I noticed that my printer, a HP Photosmart, wasn't found. When i went into System Settings -> Printers, i was told " No Printer services Bad file descriptor".
When i used the HP utility, it will find the printer, but no PDD file, and would not install the printer.
After a bit of Googling, i found that you have to start Cups manually with:

sudo /usr/sbin/cupsd -f

.
Sure enough, after that, the printer showed up in both System Settings and the HP utility.
But it is not persistent and have to issue that command after every restart.
Could this be a bug, and is there a way to make it persistant

It is a wireless printer and i never had problem before with any release, and it was working before with this release, 14.10, but then it just stopped.

So its a bit of a mistery why yours starts and mine doesn't.
It's no big deal, just a bit odd.
I did try to add that command as a shell script in System Settings->Autostart, but that buggered the system a bit and had to boot into Mint to delete ~/.KDE/Autostart.

You should have:

~ $ ls -al /etc/init.d/cup*
-rwxr-xr-x 1 root root 2816 Nov  4 02:53 /etc/init.d/cups
-rwxr-xr-x 1 root root 1961 Jul 28 02:17 /etc/init.d/cups-browsed

Try stopping and starting from a command line to see if you get any errors:

$ sudo service cups stop
$ sudo service cups start

[GerardV]

Ronw,

This the output from that command:

~$ ls -al /etc/init.d/cup*
-rwxr-xr-x 1 root root 2816 Aug 15 03:24 /etc/init.d/cups
-rwxr-xr-x 1 root root 1961 Apr  8  2014 /etc/init.d/cups-browsed
gerard@gerard-Satellite-L750:~$

So that appears to be correct as well.

Stop/ Start command output:

~$ sudo service cups stop
[sudo] password for gerard: 
cups stop/waiting
gerard@gerard-Satellite-L750:~$ sudo service cups start
cups start/running, process 3537

No apparent errors here either.

[oshunluvr]

Anything in dmesg after boot up? Sounds like something is causing it to fail to start initially, but not in the way later.

[GerardV]

oshunluvr, the only references to cups i could find are:

What is a HUP signal and why would it kill cups i wonder.

[oshunluvr]

The first part looks normal to me.

I have read about apparmor blocking cups sometimes. Personally, I always remove apparmor so I can't comment on it much.

Is there anything in /var/log/cups/error_log ?

[GerardV]

oshulover, this is the log from the last couple of days

However, i have rebooted a halve dozen times since, and every time the printer showed up.
A bit of a mistery and a bit annoying that i dit not find a cause. Systemd quirk perhaps?
So i am going to mark this as solved and thanks all you guys for your help and suggestions.

[oshunluvr]

Looks like maybe your hosts file and/or cupsd.conf have something slightly wrong. If you want to trouble shoot further, post those two files and we'll have a look.

I would also re-install hplip and re-run hp-config. Could be a missing ppd file or a mis-configured printer address assignment.

Finally, if some other process is trying to use port 631, that would cause what you're seeing. It's not likely, but possible. To check this, enter this in a terminal:

sudo ss -lpn|grep 631

Output should look like:

tcp    UNCONN     0      0                      *:631                   *:*      users:(("cups-browsed",2046,8))

I have a similar problem. I got my printer installed a working a while back but the other day it stopped working! I tried this command on my computer. As you can see the last colum is different from what you get:

Looks to me like cupsd is running twice.

Try killall cupsd until it returns no process found and then manually start cupsd with sudo service cupsd restart
