I'm on Ubuntu 18.04. If I try to print a PDF from the default viewer, it displays a message to say that printing completed successfully, but nothing comes out of the printer. If I open the same PDF in the Chrome browser I can print it from there. How can I troubleshoot this problem?

Edit #1:

erik@laptop:~$ lpstat -t 
scheduler is running 
system default destination: MG2400-series 
device for MG2400-series: usb://Canon/MG2400%20series?serial=B6083B&interface=1 
MG2400-series accepting requests since Sat 13 Oct 2018 12:45:08 AM CEST printer MG2400-series is idle. enabled since Sat 13 Oct 2018 12:45:08 AM CEST

Edit #2:

erik@laptop:~$ lpq
MG2400-series is ready
no entries

erik@laptop:~$ sudo cupsenable MG2400-series

erik@laptop:~$ journalctl $(type -p cupsd)

  • Do you have CUPS (Common Unix Printing System) set up and working? service cups status will tell you. Does CUPS know about your printer? lpstat -t

  • the fact that i can print the PDF just fine from Chrome, isn't that proof that the printer is working? i can print from other apps too, just not the default PDF reader. Oct 12, 2018 at 23:14
  • Generally, editing one's post, and adding the additional information there, rather than in comments, is preferred. I'll do it for you this time.

  • You're missing a line that I see in MY lpstat -t. Right after printer xxx is idle, I see "ready to print". Try lpq, sudo cupsenable MG2400-series. Check the logs journalctl $(type -p cupsd), check more logs in /var/spool/cups/

well. i never found a fix for this. i have established that printing works perfectly fine for everything except for the default PDF viewer. to work around the problem i open the PDF in any other app, e.g. Chrome, and print it from there.

edit. it fixed itself. i had plugged the printer in to a USB hub. when i plugged it directly into the laptop it downloaded another driver and after that it started working.
