It's quite a while ago that Apple MacOS 10.7 has shipped, but Kyocera has also in March 2012 still no functioning drivers for color prints on this device in stock. The expression on the FS-5150DN C takes place painfully slow (one page A4 can easily take 15 minutes), and if you want to print multiple copies, the lame procedure is repeated for each sheet. The quality would be quite appealing. The hotline is a loss, a sent in for inspection file is since 2 weeks at Kyocera Support for troubleshooting, no answer so far.
