1 surprise era, the driver for this printer is installed natively on Windows 7, with view of the level of thunder, Samsung pilot messages display. Second surprise, the print quality and speed, great. 3rd surprise, I launch a print 153 pages, no worries, the imrimante starts scrolls sheet by printing, as this is a big impression I perceived that this printer has a probe against overheating . By the 100th page, it has to cool drive forward, and then resume on until the end. Reasonable consumption of toner. Conclusion I was amazed! Note it is a Samsung, and at a given price for me but good. More than to see the time: Do not forget to register on their website for the guarantee.
