Print speed and quality tests
Brother advertises print speeds up to 30 ppm in both black and white and color for the HL-4570cdwt and I found that to be accurate during our testing. When printing two copies of our 40-page black and white text document in Normal mode, the HL-4570cdwt averaged print speeds up to 30 ppm with a first page out in eight seconds and an overall print time of three minutes. It took half the time – a minute and a half – to print a single copy of our 40-page black text document.
I saw no difference in speed when printing color documents; the first page out was just as quick – around eight seconds – and an average print speed of 30 ppm. I did notice a slight speed reduction when the HL-4570cdwt had to switch drawers (I intentionally let the 250-sheet drawer run out) because of a slight pause, around 15 seconds or so.
The print quality was good when printing in both blackand white and color. I printed a full color brochure on the HL-4570cdwt and scanned it in for viewing purposes. The colors were bright and varied and the text was crisp.
I also noticed an occasional pause in the middle of very large jobs, almost like the printer was catching its breath. It usually lasted 15 to 20 seconds and slowed print speeds down only slightly. In the end, the printer usually made up for the pause in the overall print times.
The HL-4570cdwt does offer automatic double-sided printing (duplexing). It took just under three minutes to print our 40-page black and white text document double sided with a first page out in about 20 seconds and average print speed of 8 ppm (16 pages double sided).
A Toner Saver mode is also offered standard with the HL-4570cdwt. There were no print speed increases or decreases to mention but the draft quality was quite good. I would recommend users print using the toner saver mode as much as possible when printing in black and white or when printing rough drafts in color.
The Brother HL-4570cdwt is Energy Star qualified and after running our energy tests I can see why. The HL-4570cdwt uses the same amount of energy as many all-in-one inkjets I’ve reviewed in ready and sleep modes and the print energy usage was very consistent.
In ready mode, with the LCD backlit, the HL-4570cdwt pulls about 9 W of energy. When it drops into sleep mode, with the LCD dark, the HL-4570cdwt pulls in about 7 W of energy.
Whether printing black and white or color documents, the HL-4570cdwt was incredibly consistent, staying in a range for 500-600 W throughout the print job. The only time we saw higher number was when the printer was warming up before printing with spikes near 900 to 1000 W of energy. But this pull of energy lasted only the length of processing, which was typically a few seconds.
During the actual warm up of the printer – after it’s been turned on or connected to power – the energy usage was high, spiking at about 1000 W. It typically took less than a minute for the HL-4570cdwt to warm up.
