Very happy with the Brother HL-L6300DW. Yhe only thing that I noticed is that went printing multiple pages, say 50, the printer pauses a lot to, as it seems "catch it's breath" which slows the printing speed. Never had that problem with the Brother HL-5470.

The HL-L6300DW is an extraordinary, best of class laser printer. Cannot think of anything negative to say. The printer does its job spectacularly well. There are no issues with it. I would recommend it to anyone.

I have a tax office and this printer has stepped up to the task. I'm actually still using the "beginning" toner cartridge although it is about done. We go through a lot of paper and I've not had so much as a misfeed. If there is any negative comment I can make it's that the alpha-numeric keypad is a little finicky and could use some improvement.

This is a great printer so far, and remarkable for the price. However, two things stop it from getting a five star rating. One is that, when printing more than about 30 pages at a time, the papers start to mess up. Also, we are a public library, so the off button is right up front, too easily accessible to patrons.

After a few seconds of contemplation, spits out print job very fast. Awkward envelope handling, After printer driver updated, the printer no longer automatically duplexes. Requires saving document as a pdf and picking the 2 sided option in that print screen. Annoying,

Printer worked well with Windows computers. The support for AirPrint is dismal. The printer locks up the iPad / iPhone until after the printer warms up and the print finishes. This is unacceptable. The printer goes into low power mode and does not wake up. The low power, sleep mode, had to be disabled to get the printer to work. I have the printer away and replaced it with an HP 4001 printer that did not have the problems that the Brother demonstrated. Ow power mode

I upgraded from a 6200 and paid twice the price so even though this machine is much slower to begin a print job which I can live with, but the print job occasionally has little black marks over some of the pages. So far it's okay but waiting to see how long before the pages start looking smudgy like the 6200 did right after I replaced the fuser unit or whatever you call it so I was faced with a new one or upgrading to this one. I print 700 or 800 tax returns each season on this printer and don't expect it will last forever like my old HP seemed to but for the price one season isn't that bad.

I love the fact that this printer is fast, and it prints darker text than my old printer (a different brand). Unfortunately, this printer has a problem when it is cold -- i.e., if it hasn't printed anything in a few hours. The first couple prints come out with toner across the top inch of the page. It looks like dirt. I tried wiping the drum, cleaning the fuser wire, and setting the driver to "Improve toner fixing", but no luck. I was hoping a firmware update would fix it by forcing the fuser to heat up a bit more before creating the first print, but the recent firmware update actually made the problem worse.

I previously had the HL-L5200DW and was able to print from the MP Tray by just placing an envelope or piece of paper in it. Now you are required to open up the the back of the printer, make several modifications to the printer settings to print. Forget about printing envelopes from Microsoft Word, almost impossible. Technical support was useless and resolving the issue.

1st printer was smelling hot all the time and started to crinkle the papers. They replaced with a refurbished one in a little over a month it is not printing in spots.
