You seem to assume that when the slow printing occurs, some printing-related process wold be consuming a lot of CPU. That is not the case.
I've just observed a superslow printing. It would print a line, then wait like 10 seconds, then print another line, etc. By the time I had found this bug report again (because I remembered you asked me to post the output of some command if it occurred again) printing was already finished. So I couldn't check top (which now I know is what I was supposed to check), but I can tell cpu usage had not become high because when it does, I notice the increase in the cooler fan speed. I printed another document so that I could try what you ask but then the printing happened at a normal speed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1262308 Title: Printing has become super slow.
