Yes, these are new goods.

Yes

Unfortunately not in use with an Apple operating system.

So far I have had no problems using non-original cartridges.

Hello VanErn95 No, the machine can only print. Look for an MFC or DCP, e.g. DCP-L3510, L3550 or MFC-L3730, L3750 or L3770.

Hello, no only print from PC or with App AirPrint.

The following compatible operating systems are listed on Brother's website for the printer: Windows 10, Windows 8, Windows 7, Windows Server 2012R2, Windows Server 2012, Windows Server 2016, Windows Server 2008R2, Windows Server 2008. macOS X 10.11.6, 10.12.X, 10.13.X. Linux CUPS, LPD/LPRng

Hello BetülG The C/M/Y colour toners must remain in the machine! The BK toner must of course be OK (life >1%) for B/W printing. For monochrome printing, it is best to set this in the menu of the printer and also in the printer driver to "monochrome". Greetings

The toners from the TN-243 series fit the bill. We recommend the Brother TN-243 multipack at CHF 162 for the four colours. But please don't be surprised: the toners don't really last long.

The toners are filled. I cannot say whether they are 100% or 75% full. However, with these toners, I can generally print noticeably fewer pages with this printer than with the previous model HL-3150. Otherwise, I am very satisfied with the printer.

Hello Lugur20 There are many small differences. Just do a quick product comparison. Duplex printing: This is also called automatic 2-sided printing. This means that the device automatically prints the front and back sides of a sheet in one pass (if desired). With the simpler device (HL-L3210CW, D missing = NO duplex printing) this is also possible, but the paper printed on one side must be turned manually and put back in the drawer. Greetings

If you look at the compatible first cartridges, they are all single, not just black. I hope this clarifies your question.
