My previous Brother 5050 mono laser printer was incredibly cheap to run and was still working well after 70000 copies (in seven years). The drum was supposed to last only 20000 copies, but I only needed two in all that time, as the drum counter can be overridden to extend its life. The printer mechanism was showing signs of wear, however, and a third drum would have soon be needed so I decided to replace the printer instead.
I'm extremely pleased with its replacement. The HL-5370DW's extra facilities work superbly well. It connects to my wireless network seemlessly - if I print a document to it whilst it is switched off, the job just sits in the computer's printer queue until the printer is powered up. Thereafter, the document is printed in seconds - the printer reconnects to the network and prints without intervention.
The duplex facility also works well, but is switched off by default. (This can be reversed in the printer driver, however. The ability to reprint from the control buttons on the printer was similarly switched off by default, but I've switched that permanently on in the printer driver controls. The reprint facilty also enables control of the number of copies printed from the printer). When duplex is used, printing slows down marginally but there's a great gain in convenience.
Print quality is also very good - text is sharp and the quality of photographs is noticeably better than my previous Brother - which itself was acceptable.
Only two slight negatives. The plastic fold-down tray for the manual feed seems rather fragile, although it does its job adequately - just handle with care! Finally the rear door seems to be needed more than on my old printer, which would print envelopes easily using the normal paper path. Brother recommend that the rear door is opened whilst printing envelopes and card - just allow space behind the printer if you plan to print on either of these media.
In summary, an exceptionally good printer, so far, at a very reasonable price. The cost of consumables for this printer can't be beaten. Oh, I've passed my old printer on to my son, who is well pleased!!
