CUPS - How to reprint jobs?

Maniaxx · 2016-11-06 21:10:27

Hallo,
i want to keep print jobs in CUPS so i can reprint jobs by simply clicking a button in webinterface, As far as i understand this is done by 'PreserveJobFiles' and it is set by default already (1d = 1 day). The webinterface confirms this (sorry for not being in english. I have no clue how to set this).

These standard values (500, 1d) are not set in cupsd.conf as they are standard values. If i set them there explicitly they do change in webinterface as well so i guess standard values should be ok.

The problem is it doesn't work. I can see the jobs listed in the 'print job history' with original file size, date, user and such but there is no control button on the right side to print the job (they are very likely not saved). Also, if i look in /var/spool/cups (i guess that's the folder where jobs are saved) there are sequentially named files (with correct count) but they don't seem to contain any print data, just meta and infodata (they are all around 1k in size - too small).

Anyone know why jobs are not saved/preserved properly here? Does it work for anyone?

Also, whenever i try to change config (on the page of the screenshot above) the service dies and i have to restart it manually. Changes are saved properly though. Anyone suffering from that as well?

Are you using a DE ?

If so, are system-config-printer and cups-pk-helper installed ?

Maniaxx · 2016-11-07 18:34:09

I'm using XFCE. I have none of your mentioned packages installed. CUPS configuration is done via Firefox (http://localhost:631).

Does it work for you?

Edit: I installed the apps.
'system-config-printer' freezes when i try to change that setting. The CUPS service doesn't crash though.

Edit2: These are the last lines of cupsd 'debug' log after crash (by web interface):

Can someone test these commands? Does it crash the service on your side as well?

cupsctl PreserveJobFiles=31d
systemctl status org.cups.cupsd.service

Try as root (sudo cupsctl) if as regular user doesn't work.

Restart service (if necessary):

sudo systemctl restart org.cups.cupsd.service

Eveything in cups /localhost works for me , but i'm not booting with systemd so not using those services .

I can think of a few things to narrow down possible causes though :

- try a different browser
- start another environment then xfce , preferably a windowmanager one instead of a full-blown DE and check if cups works there.

- parts of cups web-interface need root rights, do you have gksu or kdesu installed ?

That's interesting because the bug has been confirmed on a second system.
Just to make completely sure. The command above (cupsctl) does work for you on 2.2.1 without crashing the service getting the '/usr/bin/cupsd' daemon killed?

No errors, but that's without any systemd stuff running .

Please try this:

cupsctl PreserveJobFiles=28d
ps -aux | grep cups

The single command 'cupsctl' would revive the daemon.

That's CUPS v2.2.1?
What version is this exactly? Which source/patches?

Lone_Wolf · 2016-11-14 16:30:16

it's the stock cups-2.2.1-1 from [extra] .

My booting with openrc means 99.9% of systemd doesn'twork ,including all service/socket relatedthings.
It also means i don't have a valid logind/polkit user sesssion .

To mimic that behaviour on a system with systemd as PID 1, I suggest you disable any cups related systemd services.
Start cupsd as root , startX and use cupsctl .
The result should help to narrow down possible causes .
