Office inside the inkjet printer is actually very good, but they would say that some people are using inkjet printer at the time did not know how to operate, I think they are very attention steps of it, so that it does not know how to operate it, in my opinion inkjet printer operation is the easiest, do not know how they do, if not very concerned about their job, then there will be such a problem, I do not want to let yourself kind of problems, so that I will note that, under normal circumstances I would not let people say the same thing twice, and I think that seems to be nothing necessary.
