The system runs out of RAM
Kill RAM intensive processes, or use swap.
I have installed CUPS on my Raspberry Pi. It was connected to a USB printer and made it accessible via my LAN. It had been working very well until the recent. In these few weeks, somehow the printer does not print.
I entered the CUPS web interface of my Raspberry Pi and tried printing a test page. Funny enough. It claimed that the print job was completed, despite that the printer did nothing.
Then I dig up /var/log/cups/access_log. Here is what's inside.
localhost - - [10/May/2016:14:37:12 +0800] "POST /printers/Canon_MG2400_series HTTP/1.1" 200 422 Print-Job successful-ok
It claimed that the print is a success. Obviously that's not true!
Then I dig up /var/log/cups/error_log. Unfortunately, there was nothing inside.
Then I started trying stuffs like:
None worked! :(
Then I figured out that there is something called LogLevel in CUPS config. I modified it as follows:
And I restarted CUPS. Then I noticed the following messages appeared in /var/log/cups/error_log:
D [10/May/2016:14:37:20 +0800] [Job 136] Error: /undefined in --setpagedevice-- ... D [10/May/2016:14:37:20 +0800] [Job 136] Last OS error: Cannot allocate memory D [10/May/2016:14:37:20 +0800] [Job 136] GPL Ghostscript 9.05: Unrecoverable error, exit code 1 ... I [10/May/2016:14:37:22 +0800] [Job 136] Job completed.
What? Obviously something went wrong! How on the earth could the level of that message merely be a debug? I think that should be at least a warn! More importantly, how come it is called "Job completed"? I think that should be "Job Failed" instead! :<
After that, I increased the swap space. And remote printing starts working again. :D
Took me a few hours to figure that out. I couldn't find this solution in Google. That's why I blog about this. Hopefully someone somewhere would somehow find this blogpost helpful.
UPDATE: I've filed a bug report to the CUPS developers. Hopefully it will be fixed soon.
I have the exact same problem. my printer does make the sound of warming up, getting ready to print but Abruptly stops and no print is coming out of the printer.
The error_log says:

what can i do to fix this?
good. thanks for remind
I had the exact same problem on my Pi Zero, and adding a swap file solved it. Thank you!
