I've had this issue since upgrading to 18.04 now, on both Xubuntu and regular Ubuntu, with multiple programs and it's really frustrating.
Whenever I start a print job on my printer (Epson WF-7015), it's a gamble if the document is printed or not. Sometimes, it will print without any issues, other times, the printer will halt halfway through, the print queue will show the job as "paused" and the printout has fading lines as if the ink was empty (however, it's not, this happens with new cartridges).
I can then manually delete the print job and restart it, but I've wasted a lot of high-quality paper already, not knowing if the printing will succeed or not.
Has anybody got any experience with this issue, could help with troubleshooting or offer a solution to this problem?
Here's the output of /var/log/cups/error_log.1, corresponding to the last unsuccessful print:
