It still does not work, even with that new file. I followed steps on that wiki page, and here is the error_log.
Following the steps in wiki, I noticed that there was no file cupsys. I then went to synaptic and installed it (cups was there, just not cupsys), but it did not appear in the location mentioned in wiki page. Thus instead of cupsys restart I had to do cups restart.
