*) Above displayed settings are meant as guidance to find your optimal print settings. These ranges in settings should work for most printers, but please do feel free to experiment outside these ranges if you think it is suitable for your printer. There is a lot of different type of printers, hot-ends and printer offset that it is extremely difficult to give an overall one-size-fits-all setting.
